Problems solved by technology

However, the boiling point of the solvent is too high, or sometimes different amounts or types of dopants must be mixed according to different conjugated polymers to achieve better conductivity, which will lead to complicated steps and residual organic solvents when preparing conductive films. In addition, the preparation of the doped conductive polymer solution will have more uncertainties due to the complicated steps

Embodiment 1

[0073] Example 1: Application of Conductive Polymer Solution in Electrolytic Capacitor

[0074] Firstly, an aluminum sheet was oxidized for 30 minutes with a voltage of 40V to form a layer of porous aluminum oxide film. After chemical formation, the test piece was rinsed with deionized water and dried in an oven. Next, drop conductive polyaniline solution (conductive polyaniline (structure such as formula (17) dissolved in hexafluoroisopropanol)) on the porous etched aluminum oxide foil, and then coat it with a layer of carbon glue after it dries. Then send it to the oven for drying to remove the solvent. Then evenly coat a layer of silver glue on the surface of the carbon glue, and then dry it in the oven. Finally, cover the silver glue with gold foil and clamp it with the alligator clip connected to the negative electrode. The crocodile clip connected to the positive electrode clamps the wire, and the capacitance property can be measured. The results are shown in Table 1, w...

[0079] Example 2: Application of Conductive Polymer Solution in Light-Emitting Diodes

[0080] Drop a drop of the conductive polyaniline solution in Example 1 on the cleaned ITO glass surface, and after it dries to form a film, a layer of poly[(2-((2-ethyl-hexyl) -oxy)-5-methoxy-p-phenylene)vinylene](MEH-PPV) (the solution used was dissolving 6 mg of MEH-PPV in 1 ml of toluene). Coated a layer of thickness on the MEH-PPV film by vacuum evaporation Al as the cathode can be assembled into a polymer light-emitting diode with a double-layer structure with a conductive polyaniline film as the hole transport layer. The same method was used to assemble a single-layer structure of polymer light-emitting diodes without conductive polyaniline film. Compare two polymer light-emitting diode components with different structures and measure their current-voltage curve (Current-Voltage Curve) and potential-brightness curve (Voltage-Brightness Curve) respectively (the power supply and curr...

[0085] Example 3: Application of Conductive Polymer Solution in Chemical Sensor

[0086] Drop a drop of conductive polyaniline solution (same as Example 1) on the surface of 10 cleaned polyethylene terephthalate (Polyethylene terephthalate, PET), and make 10 conductive polyaniline films with the same thickness after drying . Prepare 10 cups of L-vitamin C aqueous solution in addition, the concentration is 0ppm, 10ppm respectively -3 ppm, 10 -2 ppm, 10 -1 ppm, 1ppm, 10ppm, 100ppm, 1000ppm, 10 4 ppm, 5x10 4 ppm, and the pH value of the L-vitamin C aqueous solution was adjusted to 1 with hydrochloric acid aqueous solution, and the conductive polyaniline film was immersed in different concentrations of L-vitamin C aqueous solution for three minutes, and the UV / visible light absorption spectrum of the conductive polyaniline film was detected. . The result is as figure 1 As shown, the conductive polyaniline film is used as a chemical sensor, immersed in an aqueous solution of...

Abstract

A conductive polymer solution includes one doped conjugated polymer and one organic solvent. The doped conjugated polymer has electrical conductivity, and is selected from the group consisting of polyacetylenes, polypyrroles, polyparaphenylenes, polythiophenes, polyfurans, poly(3,4-ethylenedioxythiophenes), poly(3,4-propylenedioxythiophenes) (PProDOT), polythianaphthenes, polyanilines, and their copolymers, derivatives and combinations. The organic solvent is selected from the group consisting of a fluorinated organic solvent, mixture solvents containing fluorinated organic solvents, and mixture solvents containing fluorinated and non-fluorinated organic solvents. The organic solvent is mixed with the doped conjugated polymer. A preparation method of the conductive polymer solution is also disclosed.

Description

technical field [0001] The invention relates to a polymer solution and a preparation method thereof, in particular to a conductive polymer solution and a preparation method thereof. Background technique [0002] Since conjugated polymers have the characteristics of polymers and semiconductors or conductors at the same time, their conductive and insulating properties can be reversibly changed by redox or adding acid and alkali, and are often used in solar cells, in the form of conductive polymer films. Capacitors, light-emitting diodes, chemical sensors, pattern etching, corrosion resistance, electrode materials, EMI shielding, electrochromic and antistatic (ESD) components. Generally speaking, commonly used conjugated polymers include polyacetylenes, polypyrroles, polyparaphenylenes, polythiophenes, polyfurans, polybenzothiophenes, poly Anilines (polyanilines, PANI) and their derivatives or copolymers. In order to prepare a conductive polymer film, most of the known techno...
