Embodiment 1
[0029] 1) Soak (40cmx300cm) PET in pure aniline solution for 10 hours at room temperature, the characterization results of pure PET film are as follows Figure 1a ;
[0030] 2) Take 25mL of TiCl 4 Slowly added dropwise into 1000mL ice water under vigorous stirring to obtain Ti 4+ colorless transparent solution. Then, 5% ammonia water was added dropwise to the solution to obtain a white precipitate, which was washed several times until chloride ions could not be detected. Then add a certain amount of H 2 o 2 The resulting precipitate was dissolved to obtain a clear orange solution, which was subsequently rehydrated to Ti 4+ The particle concentration is 0.12mol / L. Then, using metal platinum (Pt) as a catalyst, the resulting solution was stirred at room temperature for 24 hours, so that excess hydrogen peroxide was completely decomposed;
[0031] 3) Add the PET film adsorbed with aniline monomer to the titanium peroxide solution prepared above, soak at 80°C for 30 minutes ...
Embodiment 2
[0033] 1) Soak (40cmx300cm) PET film in pure pyrrole solution at room temperature for 12 hours;
[0034] 2) Use a certain amount of 30% H 2 o 2 dissolve V 2 o 5 A clear brown aqueous solution was obtained, followed by replenishment to V 5+ The particle concentration is 0.10mol / L, and then using metal platinum (Pt) as a catalyst, the obtained solution is stirred at room temperature for 24 hours, so that the excess hydrogen peroxide is completely decomposed;
[0035] 3) Add the PET film adsorbed with pyrrole monomer to the titanium peroxide solution prepared above, soak at a constant temperature of 70°C for 12h and obtain V 2 o 5 -PET flexible functional film, the characterization results are as follows Figure 1c , f.
Embodiment 3
[0037] 1) Soak (40cmx300cm) PET film in thiophene solution at room temperature for 15 hours;
[0038] 2) Take a certain amount of metal molybdenum powder (Mo), add H 2 o2 solution, a light yellow transparent solution was obtained, and then replenished to Mo 6 + The particle concentration is 0.05mol / L, and then using metal platinum (Pt) as a catalyst, the resulting solution is stirred at room temperature for 24 hours to completely decompose excess hydrogen peroxide;
[0039] 3) Add the PET film adsorbed with 3,4-ethylenedioxythiophene to the molybdenum peroxide solution prepared above, soak at 60°C for 20 hours to obtain MoO 3 -PET flexible functional film, the characterization results are as follows Figure 1d ,g.
