Embodiment 1
[0034] A method for manufacturing a conductive polymer-graphene oxide-porous carbon nanotube composite intermediate layer, comprising the following steps:
[0035] (1) Preparation of graphene oxide (GO@CP) with conductive polymer arrays grown on the surface
[0036]Add conductive high polymer monomer (including but not limited to aniline, pyrrole, etc.) solution. Graphene oxide powder (GO) was then added to the solution at a ratio of 1 mg:1 mL, and ultrasonically dispersed for 1 h to obtain a uniform suspension, called solution A. Add ammonium peroxide (APS) to 1 volume of 1 mol / L aqueous sulfuric acid solution, the amount of which is 4 times that of the conductive high polymer monomer in solution A, and then stir for 10 min to obtain solution B. After incubating solution A and solution B at -5°C for 30min, quickly add solution B to solution A, continue to incubate at -5°C and stir for 12h. The resulting solid was filtered and washed with deionized water until the pH of the...
