Abstract
Description
Technical Field
[0001] The invention relates to the technical field of oil-water separation material and photothermal material preparation, and in particular to a preparation method and application of a conjugated microporous polymer aerogel and a polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel. Background Art
[0002] With the rapid development of modern industry and agriculture, increasingly serious environmental pollution has had a serious impact on the sustainable development of human society, especially water pollution. Among them, marine oil spills and the discharge of industrial oily wastewater not only pose a great threat to the ecological environment and human health, but also cause significant economic losses. Therefore, how to separate oil from water and efficiently recover residual oil in oily wastewater has become a hot issue of concern to everyone.
[0003] Ideal oil-water separation adsorption materials should have excellent superhydrophobicity, strong adsorption capacity and outstanding cyclic stability. In recent years, the development of materials with superwetting surfaces and their application in oil-water separation has received widespread attention. Conjugated microporous polymers (CMPs) have gradually become a research hotspot due to their large specific surface area, high porosity, and strong chemical stability. However, traditionally prepared CMPs are usually in powder form, which is not only difficult to dissolve and recycle, but also may cause secondary pollution. These problems greatly limit the application scope of CMPs in actual use. Therefore, changing the building monomer to prepare bulk conjugated microporous polymer aerogels has become the main research direction.
[0004] Currently, the use of clean and renewable energy to produce fresh water and purify water resources has become a hot topic. Sunlight, as a promising unlimited energy source, can produce fresh water through steam generation, purification and distillation. In the solar-driven interfacial evaporation (SSG) system, the photothermal material converts sunlight into heat, and the substrate simultaneously transfers water to the photothermal layer to generate steam. Based on this idea, the purification and evaporation treatment of oily wastewater needs to be studied. Summary of the invention
[0005] In order to solve the problems existing in the prior art, the present invention provides a method for preparing a conjugated microporous polymer aerogel and a polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel, and also relates to the application of aerogel in oil-water separation, evaporation of oily wastewater, purification treatment, etc.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] Figure 1 The invention provides a preparation route for the conjugated microporous polymer aerogel and the polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel.
[0042] Example 1 Preparation of Conjugated Microporous Polymer Aerogels (TCMPs)
[0043] First, 2,4,6-tri-(3-bromophenyl)-(1,3,5)triazine (546.05 mg, 1 mmol), 1,4-diethynylbenzene (192.25 mg, 1.5 mmol), CuI (50 mg), Pd(PPh3)2Cl2 (150 mg) were added to a round-bottom flask containing toluene (7.5 mL) and Et3N (7.5 mL) in sequence. Then, the round-bottom flask was sealed and protected with N2, and the reaction was carried out in an oil bath at 80°C for 72 hours. After the reaction, the round-bottom flask was cooled to room temperature, and chloroform, toluene, water and methanol were used to wash the solid in sequence. Finally, the solid was placed in a Soxhlet extractor, extracted and washed with methanol for 72 hours, and dried in vacuum at 60°C for 24 hours to obtain a conjugated microporous polymer named TCMPs.
[0044] During the reaction, the molar ratios of 2,4,6-tris-(3-bromophenyl)-(1,3,5)triazine to 1,4-diethynylbenzene were 2:3, 1:1 and 1:2, respectively, and the obtained products were named TCMPs-1, TCMPs-2 and TCMPs-3, respectively.
[0045] Figure 2 In the figure, a and b, c and, e and f are scanning electron microscope images of TCMPs-1, TCMPs-2 and TCMPs-3, respectively. gi is the energy dispersive spectrometer image of TCMPs.
[0046] Figure 2 The microstructure of TCMPs was studied using scanning electron microscopy. Figure 2 af shows that the material presents an intertwined three-dimensional network hollow nanotube structure. The spatial structure of TCMPs-1 is tighter and the branch size is moderate. It is speculated that TCMPs-1 has the best performance. Figure 2 gi is the EDS spectrum of TCMPs, from which it can be seen that C and N elements are evenly distributed in TCMPs.

[0048] Figure 3 In the 13 C NMR was used to characterize the chemical structure and skeleton information of TCMPs. Figure 3 In ab, the results shown at each peak can preliminarily prove that a conjugated microporous polymer has been synthesized. Figure 3 As shown in Figure c, TCMPs-1, TCMPs-2, and TCMPs-3 were subjected to compression mechanical property tests, and the results showed that the materials had good mechanical properties, among which TCMPs-1 could withstand relatively strong mechanical strength. Combined with the scanning electron micrograph, TCMPs-1 was selected as the research object in the subsequent preparation of polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel experiments. Figure 3 d shows that TCMPs-1 has very excellent elastic and mechanical properties.
[0049] Figure 4 In the figure, a is the XRD analysis diagram of TCMPs-1. b is the TGA curve diagram of TCMPs-1. c is the N2 adsorption-desorption isotherm diagram. d is the pore size distribution curve diagram.
[0050] Figure 4 aThrough the analysis of XRD patterns, TCMPs have an amorphous structure, such as Figure 4 As shown in b, TGA was used to prove that TCMPs-1 has good thermal stability. Figure 4 The pore properties of TCMPs were studied by mercury intrusion porosimetry. The BET specific surface area of CMPs-1 was 16.6 m 2 g -1, the total pore volume is 0.002 cm 3 g -1 The pore size is 16.66 nm, indicating the existence of micropores and mesopores in TCMPs-1.

[0052] Figure 5 The wettability of TCMPs-1 was studied by using a water contact angle meter. The water contact angle of TCMPs-1 was 151° and the oil contact angle was 0°. It was oleophilic and superhydrophobic. The results showed that TCMPs-1 is an ideal material for oil-water separation.
[0053] Example 2 Preparation of polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel (TCMPs-PPy)
[0054] (1) Preparation of conjugated microporous polymer composite aerogels (TCMPs): same as in Example 1.
[0055] (2) First, prepare solution A: 1.37g (NH4)2S2O8 and 25.0mL deionized water are added to a 10.0mL spray bottle in sequence; prepare solution B: 0.42mL pyrrole, 25.0mL isopropanol and 0.92mL phytic acid are added to a 10.0mL spray bottle in sequence. Prepare AB glue: Add epoxy resin A glue (1g), epoxy resin B glue (1g), ethanol (0.5mL) and acetone (0.5mL) into the sample box, mix and stir evenly, and then ultrasonicate for 10 minutes. Secondly, after cooling to 0℃, alternately spray solutions B and A on a melamine sponge with a specification of 2.5×1.5×0.8, ensuring that all surfaces of the sponge are completely coated with polypyrrole. Then, after reacting at room temperature for 1h, wash it several times with deionized water and dry it at 60℃ to obtain a polypyrrole-modified melamine sponge. Finally, AB glue was coated on the two interfaces of the sponge 1.5×0.8, a layer of filter paper was adhered, and then two arched TCMPs-1 were adhered. This composite polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel was named TCMPs-PPy.
[0056] Example 3 Application of the conjugated microporous polymer aerogel and polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel photothermal material of the present invention in oil-water separation, seawater desalination and oily wastewater purification.
[0057] (1) The conjugated microporous polymer aerogel prepared in Example 1 was placed in a simulated oily wastewater device containing floating oil, and the adsorption capacity of TCMPs-1 aerogel for different oils / organic solvents was analyzed by changing the type of oil. In addition, in order to explore the practical application of TCMPs-1, a vacuum-assisted collection device was designed to continuously remove oil spills on the water surface, improve the oil-water separation efficiency, and test its circulation performance.
[0058] Figure 6 Image of TCMPs-1 adsorbing diesel in water
[0059] like Figure 6 As shown in the figure, when TCMPs-1 comes into contact with diesel on the water surface, diesel is quickly adsorbed by TCMPs-1, and the water surface appears transparent blue. The results show that TCMPs-1 can effectively remove floating oil on the water surface.
[0060] Figure 7 In the figure, a is the adsorption capacity of TCMPs-1 for various oils and solvents. b is the efficiency of TCMPs-1 for oil-water separation after 5 cycles.
[0061] like Figure 7 a, using 9 kinds of oil / organic solvents (carbon tetrachloride, toluene, dichloromethane, chloroform, hexadecane, hexane, diesel, dimethyl silicone oil and crude oil) to evaluate the oil-water separation performance of TCMPs-1 aerogel. The adsorption amount of TCMPs-1 aerogel on various oils varies between 9 and 25 times of its own weight, and the adsorption amount of TCMPs-1 is related to the density and viscosity of the oil / organic solvent.
[0062] Figure 8 In the figure, a is a schematic diagram of the vacuum pump continuously separating water and oil / organic solvent. b is a picture of TCMPs-1 continuously absorbing oil in water.
[0063] like Figure 8 a shows that under the action of the vacuum pump, the oil / organic solvent is continuously sucked into the oil collection cylinder through the hose, which greatly improves the oil-water separation efficiency of TCMPs-1. Figure 7 b. After 5 cycles of testing, the diesel / water separation efficiency can still reach over 87%, and it still has good oil-water separation performance.
[0064] (2) The polypyrrole-modified melamine sponge / conjugated microporous polymer composite aerogel prepared in Example 2 was placed in different environments and heated to 1 sun (1 kW / m 2) for 60 minutes. The evaporation performance was tested using a simulated solar test device system in the laboratory. The mass change of water in the system was monitored in real time by an electronic analytical balance, and the temperature change at the top of the material was monitored using infrared photography technology. The evaporation rate and evaporation efficiency of TCMPs-ppy can be obtained based on the slope of the mass-time curve.
[0065] Fig. 9 In the figure, a is the curve of the mass change of pure water, TCMPs-ppy and Sponge under different sunlight conditions. b is the evaporation rate and efficiency of pure water and TCMPs-ppy under different sunlight conditions. c is the curve of the mass change of TCMPs-ppy under different oil-water conditions. d is 1kW m -2 Curve of TCMPs-ppy changing with temperature under sunlight conditions.
[0066] like Fig. 9 As shown in a, at 1kW m -2 Under strong sunlight, the mass change of TCMPs-ppy composite aerogel is more significant, and as the sunlight increases, the evaporation performance of TCMPs-ppy composite aerogel becomes stronger. Fig. 9 b, at 1kW m -2 Under sunlight, the evaporation rate and efficiency of TCMPs-ppy composite aerogel were 1.44 kg m -2 h -1 and 83.27% kg m - 2 h -1 ; at 2kW m -2 The evaporation rate and efficiency under sunlight were 2.08 kg m -2 h -1 and 61.85%; at 3kWm -2 The evaporation rate and evaporation efficiency under sunlight are 2.73 kg m -2 h -1 and 56.32%, while pure water at 1kW m -2 The evaporation rate under sunlight is not obvious, only 15.27%. The results show that TCMPs-ppy composite aerogel has good evaporation performance. Fig. 9 As shown in c, the higher the oil content, the lower the evaporation rate of the material. Fig. 9 d shows that at 1kW m -2 Under strong sunlight, the surface temperature of the material experienced a rapid rise in 10 minutes, reaching 32.3°C at 10 minutes, and then the temperature rise rate gradually decreased, reaching 39.2°C at 30 minutes.
