Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to PCT Application No. PCT / US2020 / 041851, filed July 13, 2020, U.S. Patent Application No. 17 / 000,012, filed August 21, 2020, and U.S. Patent Application No. 17 / 189,637, filed March 2, 2021, the entire contents of each of the foregoing patent applications being incorporated herein by reference.

[0002] (Technical field) FIELD OF THE DISCLOSURE The present disclosure generally relates to thermally stable and solvent resistant conductive polymer composites and methods for making the same. [Background technology]

[0003] Conjugated polymers (CPs) are widely used in all kinds of electronic devices. Doping has proven to be a powerful tool for improving the robust electrical conductivity of conjugated polymers (CPs) at high temperatures and / or in various solvent environments. However, organic doping is generally sensitive to external stimuli such as heat, moisture, and chemicals, which can cause a dedoping process. For example, thermal stress often induces and promotes conformational changes in polymer chains, further resulting in microscale or morphological disorder in conjugated polymer thin films. In doped thin films, this process is often accompanied by the release of dopant molecules, resulting in a decrease in electrical conductivity and degradation of device performance. Molecular dopants such as ferric chloride and F4TCNQ enable stable doping of poly(3-hexylthiophene) under ambient conditions, but their relatively small size makes them prone to diffusion at high temperatures, making them thermally unstable.

[0004] To achieve robust electrical conductivity in conjugated polymers (CPs) using conventional doping methods, designing novel dopants or developing new doping methods requires significant synthetic and processing efforts. Therefore, a simple, efficient design and manufacturing-friendly method for thermally stable and solvent-resistant doped systems is highly desirable.

DETAILED DESCRIPTION OF THE INVENTION

[0042] In the following description, certain specific details are set forth to provide a thorough understanding of various embodiments of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these details. Furthermore, while various embodiments of the present invention are disclosed herein, various changes and modifications can be made within the scope of the present invention in accordance with the general knowledge of those skilled in the art. Such modifications include the substitution of known equivalents for any aspect of the present invention in order to achieve the same result in substantially the same way.

[0043] Unless the context requires otherwise, throughout this specification and claims, the word "comprise" and variations thereof (e.g., "comprises," "comprising") should be interpreted in an open and inclusive sense, i.e., "including, but not limited to." Throughout this specification, the recitation of ranges of values ​​is intended to serve as a shorthand notation for individually referring to each value falling within the range, inclusive of the values ​​defining the range, each value being incorporated herein as if set forth individually herein. In this disclosure, the term "about" can allow for variation of a given numerical value or range (e.g., within 10%, 5%, or 1% of the specified numerical value, or other specified range). Additionally, the singular forms "a," "an," and "the" also include the plural of their referent unless the context clearly dictates otherwise.

[0044] Throughout this specification, the terms "one embodiment," "an embodiment," and the like mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "one embodiment," "an embodiment," and the like in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0045] The present disclosure provides thermally stable and solvent-resistant conductive polymer composites comprising a doped electron-rich host thiophene conjugated polymer and a crosslinked siloxane network.

[0046] Throughout this specification, testing of a "conductive polymer composite" or "composite" refers to testing of a composite thin film formed by depositing the composite on a glass substrate.

[0047] Various embodiments disclosed herein relate to various forms of crosslinkable silane precursors and various electron-rich host thiophene conjugated polymers for forming thermally stable and solvent-resistant conductive polymer composite thin films. The host thiophene conjugated polymers have a low oxidation potential and can be easily doped. The crosslinkable silane precursor requires at least three functional groups to form a crosslinkable siloxane network through a condensation reaction, and also has at least one dopant for the doping reaction. When a solution of the crosslinkable silane precursor is mixed with a solution of the host thiophene conjugated polymer, the crosslinkable silane precursor forms a crosslinked siloxane network within the host thiophene conjugated polymer, and simultaneously, a doping reaction occurs between the crosslinkable silane precursor and the host thiophene conjugated polymer (see Figures 1(A)-(C)). The crosslinked siloxane network is formed by mixing the crosslinkable silane precursor with the host thiophene conjugated polymer. During mixing, the functional groups capable of undergoing a condensation reaction are replaced with hydroxides from the small amount of water in chloroform, thereby generating silanol groups in the solution. As shown in Figure 1(A), a crosslinked siloxane network is formed by the condensation reaction of two adjacent silanol groups in adjacent precursors in solution. In addition, the host thiophene conjugated polymer shown in Figure 1(C) has a low oxidation potential, making it easy to dope. When a crosslinked network is formed within the host thiophene conjugated polymer by mixing a crosslinkable silane precursor with the host thiophene conjugated polymer, the dopant contained in the crosslinkable silane precursor undergoes a doping reaction with the host thiophene conjugated polymer, resulting in the production of a conductive polymer composite material as shown in Figure 1(D). The crosslinked siloxane network constrains the doped polymer, preventing rearrangement of the doped polymer chains and dopant diffusion. Furthermore, since dedoping involves changes in the three-dimensional structure and morphology, the crosslinked siloxane network also contributes to the stability of the dope. Thus, the introduction of a crosslinked siloxane network not only significantly improves the conductivity of conjugated polymers (CPs), but also improves their thermal stability and solvent resistance.

[0048] In some embodiments, the crosslinked siloxane network is formed from a crosslinkable silane precursor having the following chemical formula:

[0051] The crosslinkable silane precursors described above require at least three functional groups capable of condensation reactions to form a crosslinked siloxane network. In contrast, silane precursors with two functional groups capable of condensation reactions can form linear siloxane bridges that can bend and twist within the host thiophene conjugated polymer to form a siloxane matrix. While such siloxane matrices are not crosslinked but still constrain the polymer chains to some degree, they can significantly improve the electrical conductivity of the conjugated polymer (CP) (in some embodiments, by four to five orders of magnitude, compared with six orders of magnitude for silane precursors with at least three functional groups). However, their thermal stability is not as good as that of silane precursors with at least three functional groups.

[0054] The crosslinkable silane precursors described above require at least three functional groups capable of condensation reactions to form a crosslinked siloxane network. In contrast, silane precursors with two functional groups capable of condensation reactions can form linear siloxane bridges that can bend and twist within the host thiophene conjugated polymer to form a siloxane matrix. While such siloxane matrices are not crosslinked but still constrain the polymer chains to some degree, they can significantly improve the electrical conductivity of the conjugated polymer (CP) (in some embodiments, by four to five orders of magnitude, compared with six orders of magnitude for silane precursors with at least three functional groups). However, their thermal stability is not as good as that of silane precursors with at least three functional groups.

[0081] Example

[0082] 1. Ability to form cross-linked siloxane networks

[0083] The following various embodiments relate to a crosslinkable silane precursor having at least three chlorine groups, namely, crosslinkable 1,6-bis(trichlorosilyl)hexane (hereinafter referred to as "C6-Si"), and a dioxothiophene random copolymer containing one soluble 3,4-propylenedioxythiophene (ProDOT) unit and three electron-rich 3,4-ethylenedioxythiophene (EDOT) units, namely, a host conjugated polymer (host CP). The dioxothiophene random copolymer has the chemical formula ProDOT1-EDOT3 (PE3). For comparison, two non-crosslinkable silane precursors with one or two chlorine groups, which cannot form a crosslinked siloxane network, were also evaluated. The two non-crosslinkable silane precursors with one or two chlorine groups are referred to as the linear crosslinkable silane precursor (L6-Si) and the flowable silane precursor (F-Si), respectively. The chemical formulas of L6-Si and F-Si are shown below.

[0084] [ka]

[0085] Atomic force microscopy (AFM) phase images of the pure thiophene-conjugated polymer PE3 and conductive polymer composite thin films prepared using various silane precursors, C6-Si, L6-Si, and F-Si, are shown in Figures 2 and 3. As shown in Figure 2(B), the conductive polymer composite thin film prepared from C6-Si and PE3 exhibited clear phase separation between the thiophene-conjugated polymers, whereas this phase separation was not observed in the pure PE3 thin film, as shown in Figure 2(A). On the other hand, as shown in Figure 3, the conductive polymer composite thin films prepared from L6-Si and PE3 (Figure 3(A)) and F-Si and PE3 (Figure 3(B)) both exhibited no clear phase separation. This indicates that L6-Si can form a linear matrix that can bend and twist within the host during thin film processing, and F-Si can form a flowable matrix, but they are unable to form a crosslinked network through condensation reactions within the entire composite. The formation of a cross-linked siloxane network in the C6-Si / PE3 composite is indicated by the characteristic Si-O-Si stretching vibration at approximately 1050 cm, as indicated by the arrow in Figure 4. -1 and 1150cm -1 This is further confirmed by monitoring the presence of IR bands. Due to the lack of trichlorosilyl groups that form a crosslinked network during the condensation reaction, the L6-Si and F-Si composites form linear and fluid matrices, resulting in fewer Si-O-Si stretching vibration bands in their IR spectra. When the host CP solution was mixed with the silane precursor solution, a conductive polymer composite immediately and spontaneously formed in the solution. The solution was coated onto a substrate to form a thin film, followed by thermal annealing at 393 K. Interestingly, the temperature-dependent in situ IR spectra of the C6-Si / PE3 composite were well overlapped before and after thermal annealing at 393 K, as shown in Figure 5, indicating the simultaneous formation of a crosslinked siloxane network at room temperature.

[0086] 2. Effect of silane precursor concentration on electrical performance

[0087] The concentration of silane precursor significantly affects the electrical performance of conductive polymer composites. However, conductive polymer composites containing various silane precursors and thiophene conjugated polymers may have different optimal concentrations. Here, we investigated the effect of the concentration of specific silane precursors (C6-Si, L6-Si, and F-Si) on the electrical performance of conductive polymer composites containing a specific conjugated polymer (PE3). Figure 6 shows the electrical conductivities of three conductive polymer composites containing different concentrations of silane precursor: C6-Si / PE3, L6-Si / PE3, and F-Si / PE3. To better visualize the concentration differences, the conductivities are plotted on a logarithmic scale. Among the various silane precursor contents, all three conductive polymer composites exhibited the highest conductivity when containing approximately 56 wt% silane precursor. The conductivity of PE3 was only 10 -6While the conductivity of the three conductive polymer composites was 0.1 S / cm, most of them were above 0.1 S / cm. This significant improvement in conductivity is attributed to the presence of chlorine (a p-type dopant) and silanol (a well-known electron trap). This can be confirmed by the fact that the most phase separation was observed in C6-Si / PE3, which contained approximately 56 wt% silane precursor, as shown in the AFM phase image in Figure 7(B). Excessive silane precursor resulted in a lack of conductive domains in the composite, which resulted in decreased conductivity in all three composites containing approximately 72 wt% silane precursor in Figure 6. This is likely due to insufficient and isolated conductive domains in the composite, as shown in Figure 7(A). In addition, among the three silane precursors (crosslinked C6-Si, non-crosslinked L6-Si, and non-crosslinked F-Si), the highest conductivity increase (up to six orders of magnitude) was achieved with C6-Si / PE3 containing approximately 56 wt% silane precursor. On the other hand, the conductivity increase was low for both L6-Si / P and F-Si / PE3. When containing 56 wt% silane precursor, the C6-Si / PE3 composite with a crosslinked network had the highest chlorine species incorporated among the three composites, resulting in the highest conductivity. Because approximately 56 wt% silane precursor was found to provide the best electrical performance for the conductive polymer composites, we will use approximately 56 wt% silane precursor in all subsequent experiments unless another concentration is specified.

[0088] 3. Doping process

[0089] As shown in Figure 8, the doping process was monitored using UV-vis absorption spectra of pure PE3 and three conductive polymer composites containing approximately 56 wt% of the silane precursor: C6-Si / PE3, L6-Si / PE3, and F-Si / PE3. Each spectrum was normalized by the absorbance at 400 nm. Upon mixing the host CP with the silane precursor, a doping process simultaneously occurs between the dopant contained in the silane precursor and the host CP, resulting in the formation of a crosslinked siloxane network. The chlorine groups contained in the silane precursor act as dopants. As shown in the shaded wavelength region of Figure 8, three critical peaks (a neutral absorption band at approximately 550 nm, a polaron peak at approximately 850 nm, and a λ peak) are observed. max The neutral absorption band at about 550 nm is usually related to the band gap energy required to excite an electron from the valence band to the conduction band. The decrease in the neutral absorption peak indicates that the doping process has increased the conductivity of the polymer. The polaron peak (about 850 nm) and the bipolaron peak (about λ max ) is typically used to indicate the generation of various charge carriers along the polymer backbone upon doping. The neutral absorption peak at approximately 550 nm decreased for all three silane / PE3 composites compared to the PE3 polymer, indicating the doping process occurred in all three composites. The increase in both the polaron and bipolaron peaks further indicates the formation of the doping process in all three composites. Figure 8 also shows that both the polaron and bipolaron peaks increased most significantly for the C6-Si / PE3 composite, followed by the L6-Si / PE3 and F-Si / PE3 composites. This increase corresponds to the abundance of chlorine groups in the silane precursors. The more chlorine groups present, the greater the doping effect, resulting in an increase in both the polaron and bipolaron peaks.

[0090] 4. Thermal stability provided by cross-linked siloxane network and abundant doping

[0091] As mentioned above, all three different techniques (AFM, IR, and UV-vis absorption) revealed that the conductive polymer composite with a crosslinkable silane precursor (C6-Si / PE3) exhibited both a crosslinked siloxane network and a more extensive doping process compared to the other composites (L6-Si / PE3 and F-Si / PE3) constructed with a non-crosslinkable silane precursor and less chlorine dopant. Correspondingly, the thermal stability of these three composites was tested to investigate the influence of the crosslinked siloxane network and the extensive doping process on thermal stability. - Anions readily diffuse from non-thermally stable systems upon thermal annealing at 100°C (373K), resulting in a decrease in conductivity. If the thermal stability of a composite is good, its conductivity will not change significantly upon heating. Therefore, we investigated the change in conductivity of C6-Si / PE3, L6-Si / PE3, and F-Si / PE3 composites containing approximately 56 wt% silane precursor before and after 1 hour of thermal annealing at 373K. As shown in Figure 9, after 1 hour of thermal annealing at 373K, only the C6-Si / PE3 composite still maintained more than 90% of its original conductivity, demonstrating stable high conductivity. Meanwhile, the other composites with linear and flowable matrices showed little conductive behavior. These results indicate that the crosslinked siloxane network and doping process significantly improved thermal stability, while the linear or flowable silane matrix achieved little improvement in thermal stability. Because the dopant is contained in the silane precursor, the doping process occurs simultaneously with the crosslinking process. Herein, both the processes of doping and crosslinked siloxane network formation can be simplified as the process of crosslinked network formation.

[0092] The electrical thermal stability was further investigated by monitoring the dedoping process of the composites at high temperatures through in situ temperature-dependent UV-vis absorption spectra of the three composites (C6-Si / PE3, L6-Si / PE3, and F-Si / PE3) at various temperatures ranging from 293 K to 453 K, as shown in Figures 10(A)-(C). For each conductive polymer composite thin film, all absorbance values ​​at various temperatures were normalized to the absorbance at 400 nm at 293 K. As shown in Figure 10(A), the C6-Si / PE3 composite exhibited a λ attributed to bipolaron absorption at room temperature. max (approximately 1600 nm) shows a broad signal. maxThe bipolaron absorption peak at λ = ≈1600 nm decreased with increasing temperature. The polaron peak at λ = ≈850 nm increased with increasing temperature to 373, 393, and 413 K, then decreased slightly with increasing temperature to 433 and 453 K (although still higher than the peak at 373 K). The neutral peak at λ = ≈550 nm increased with increasing temperature. The increase in the polaron peak below 413 K is attributed to the formation of polarons from bipolarons exceeding the dedoping process. With increasing temperature to 433 K, the dedoping process dominates over the dedoping process, resulting in a slight decrease in the polaron peak. In the undoped state of conjugated polymers, the neutral peak at ≈550 nm typically dominates. The decrease in the bipolaron peak at approximately 1600 nm and the increase in the neutral peak at approximately 550 nm indicate the effectiveness of the dedoping process. Comparing Figures 10(A)–(C), it is observed that at all test temperatures, C6-Si / PE3 exhibits much higher bipolaron and polaron peaks and a much lower neutral peak than the L6-Si / PE3 and F-Si / PE3 composites. This indicates that C6-Si / PE3 has higher conductivity at the test temperatures. Meanwhile, C6-Si / PE3 exhibits a smaller decrease in the polaron and bipolaron peaks and a smaller increase in the neutral peak than the L6-Si / PE3 and F-Si / PE3 composites. The small changes in the polaron, bipolaron, and neutral peak intensities demonstrate the thermal stability of the C6-Si / PE3 composite.

[0093] Since the intensity of the bipolaron peak and the neutral peak more directly reflects the conductivity of the composite, the optical density ratio between the neutral peak (approximately 550 nm) and the bipolaron peak (approximately 1600 nm) was used to indicate the electrical conductivity and thermal stability of the composite. The smaller the optical density ratio of a composite, the higher the conductivity of the composite. The higher the temperature, the smaller the change in the optical density ratio of the composite, indicating higher thermal stability of the composite. Furthermore, the change in the optical density ratio at various elevated temperatures was evaluated for three silane / PE3 composites (C6-Si / PE3, L6-Si / PE3, and F-Si / PE3). As shown in Figure 11, the C6-Si / PE3 composite had the smallest optical density ratio among the three composites, and also the smallest change in the optical density ratio with increasing temperature. This indicates that the C6-Si / PE3 composite has the highest thermal stability among the three composites. As mentioned above, only the C6-Si / PE3 composite forms a crosslinked siloxane network. The crosslinked siloxane network in the composite effectively confines (confines) the doped polymer, restricting the movement of the doped polymer chains, thereby significantly reducing the morphological changes and dopant diffusion at high temperatures, resulting in improved thermal stability of the conductive polymer composite.

[0094] 5. Effect of the number of spacer carbon atoms in the crosslinkable silane precursor on the thermal stability of the composite

[0095] The number of spacer carbon atoms in the crosslinkable silane precursor can increase the rigidity of the crosslinked network, which can further improve the thermal stability of the composite. To investigate the effect of the number of spacer carbon atoms in the crosslinkable silane precursor on the thermal stability of the composite, two other crosslinkable chlorosilanes, namely, monotrichlorosilyl (C M Hexyltrichlorosilane having 10 spacers (C 101,10-bis(triphorosilyl)decane with a siloxane-containing siloxane (C6-Si) was compared with C6-Si. As shown in Figure 12, the conductivity of the three composites was investigated in situ at 353 K for 6 hours. All data were normalized to the corresponding conductivity at time zero. For ease of visualization, the normalized conductivity is shown on a logarithmic scale. The non-crosslinked silane precursor, L6-Si, was shown as a control. As shown in Figure 12, the conductivity of L6-Si / PE3 dropped sharply by almost two orders of magnitude in the first hour and remained at about 5% of its as-spun conductivity under prolonged thermal stress. In contrast, all three C-Si / PE3 composites showed little change in conductivity. C6-Si / PE3 and C6-Si / PE3, which have flexible spacers in the siloxane network, exhibited almost no conductivity change. 10 The conductivity of the / PE3 composite material decreased to about 60% of that of the spin-coated material, while the C M The -Si / PE3 composite maintains its electrical conductivity as spin-coated. M The excellent thermal stability of the L6-Si composite is attributed to the stiffest cross-linked network without flexible spacers in the silane precursor. The large decrease in conductivity of the L6-Si / PE3 composite indicates poor thermal stability due to the lack of a cross-linked siloxane network.

[0096] The effect of the number of spacer carbons on the thermal stability of the conductive polymer composite thin film of the present disclosure was investigated using the 1050 cm stretching vibration, which corresponds to the Si-O-Si stretching vibration. -1 and 1150cm -1 As shown in Figures 13(A) to 13(C), the C6-Si / PE3, C 10 -Si / PE3, C M The IR spectra of the three conductive polymer composites of -Si / PE3 were compared before and after thermal annealing at 393 K for 30 and 60 minutes. As indicated by the arrows in the figure, all three composites exhibited a peak at approximately 1050 cm -1 and approximately 1150 cm -1 It shows a clear IR band. M -Si / PE3 composite material has a peak at 1050-1150 cm-1 The broadest Si-O-Si band is observed between C and C, which indicates the most abundant siloxane network. M The IR spectra of the -Si / PE3 composite overlap each other, which indicates that the composite has the highest thermal stability. M The composites were prepared using the C-Si silane precursor, which has the highest thermal stability. M Due to the introduction of the -Si silane precursor, in all the following experiments, C M -Si silane precursor is used.

[0097] 6. Effect of host CP on electrical performance and thermal stability

[0098] C-Si / P x E y The electrical performance of the composite also depends on the oxidation potential of the CP. To investigate the effect of different host CPs on the electrical performance of the conductive polymer composite thin films of this disclosure, we compared composites made from three different host CPs. These three CPs are similar dioxythiophene copolymers containing soluble 3,4-propylenedioxythiophene (ProDOT) units and electron-rich 3,4-ethylenedioxythiophene (EDOT) units. x -EDOT y , P x E y (x=1; y=1, 2, 3 (separate for the three host CPs)). As shown in Figure 14, M The conductivity of the composites made from the -Si silane precursor and each CP (PE1, PE2, PE3) was compared to that of the pure polymer. After doping with the chlorosilane precursor, the conductivity of all three CPs increased significantly. For ease of visualization, the conductivity is shown on a logarithmic scale. With the pure host CP, the conductivity of PE1, PE2, and PE3 is 10 -7 , 10 -6 , 10 -6 S / cm. By mixing the polymer solution with the chlorosilane precursor, MWhen doped with -Si, the conductivity of PE1, PE2, and PE3 increased by 10 -6 , 10 -1 , and increased to 6 S / cm. The magnitude of the increase in conductivity for PE1, PE2, and PE3 was 10 3 , 10 5 , 10 6 The highest conductivity and the largest increase in conductivity were observed for PE3, which indicates that PE3 is the most susceptible to doping among the three PCs. x E y This is thought to be due to the fact that the increase in the EDOT content in the repeating units of the copolymer reduces the oxidation onset potential and electron gap (Eg) of the polymer.

[0099] 3 Cs with the same variety of CPs as above M -Si / P x E y The thermal stability of the composites was compared by the conductivity change under thermal stress shown in Figure 15 and the in situ temperature-dependent UV-vis absorption spectra shown in Figures 16(A)-(C). Figure 15 shows the in situ normalized conductivity change measured over 24 hours at 353 K. All data are from the zero C M The conductivity was normalized to that of -Si / PE3. For ease of visualization, the normalized conductivity is shown on a logarithmic scale. After baking at 353 K for 24 hours, C M -Si / PE2 and C M The conductivity of -Si / PE3 was almost unchanged (more than 80% of the original conductivity), but M The conductivity of -Si / PE1 increased slightly during the first few hours and then decreased dramatically after prolonged baking (approximately 19 hours), losing more than 90% of its original conductivity. M -Si / PE2 and C M CM-Si / PE3 shows higher thermal stability than CM-Si / PE1. Figure 16(A)-(C) shows the thermal stability of the three C M -Si / P x E yThe in situ temperature-dependent UV-vis absorption spectra of the composites are shown. For each conductive polymer composite thin film, the spectra at various temperatures were normalized to the absorbance at 400 nm at 293 K. At 293 K, C M The -Si / PE3 composites exhibited very high bipolaron absorption and very low spontaneous absorption, which is due to the C M The polaron absorption peak increased from 293 K to 393 K and decreased slightly from 413 K to 453 K. However, the final polaron absorption peak at 453 K still showed a clearly higher peak and higher intensity than the initial peak at 293 K, which is indicative of the C M This shows that the thermal stability of -Si / PE3 is high. M -Si / PE2 is C M As with -Si / PE3, the absorption peaks tend to change with increasing temperature, and the bipolaron and polaron peaks decrease. M -Si / PE1 shows even lower bipolaron and polaron band absorption and a more reduced polaron band absorption, which indicates a lower electrical conductivity and a lower thermal stability. M -Si / PE3 showed the best thermal stability.

[0100] 7. Solvent resistance of the composite thin film of the present disclosure

[0101] The conductive polymer composite material of the present disclosure not only has excellent thermal stability, but also has excellent water resistance and organic solvent resistance due to the entanglement of polymers within the crosslinked siloxane network. The solvent resistance of the C-Si / PE3 composite material of the present disclosure was confirmed by monitoring the changes in conductivity and UV-vis absorption spectrum before and after immersion in water or organic solvents commonly used in the processing of conductive polymer composites. M As shown in Figure 17, the C MThe IV curve of the -Si / PE3 composite after immersion in water for 1 hour (gray line) is only slightly deviated from the original IV curve (black line) before immersion in water. M The UV-vis absorption spectra of the -Si / PE3 composite before and after water treatment and after 1 minute of chloroform treatment are shown. For each treatment, the entire spectrum was normalized to the absorbance at 400 nm. The spectrum after 1 hour of water treatment showed a decrease of less than 10% compared to the spectrum before water treatment. In addition, the C M The -Si / PE3 composite also showed excellent robustness against organic solvents. After immersion in chloroform, the absorption peak intensity only slightly decreased, which is due to the C M -Si / PE3 composite exhibits excellent solvent resistance.

[0102] C M The excellent organic solvent resistance of the -Si / PE3 composite thin film can be visualized as shown in Figure 19(A)-(C). M The bottom halves of each of the C-Si / PE3 composite thin films were immersed in a chloroform bath for 1 minute. A clear color change was observed with the naked eye between the top and bottom halves of the pure PE3 thin film. However, the C M No significant color change was observed between the upper and lower halves of either the -Si / PE3 composite thin film or the glass substrate. M This indicates that the -Si / PE3 composite thin film has high organic solvent resistance. Similar results were observed in acetone, another commonly used organic solvent. M The excellent solvent resistance of the -Si / PE3 composite thin film was reconfirmed.
