摘要：

We prepared PPy/CNTs (polypyrrole/carbon nanotubes) composites for easy application in industrial production. Sodium dodecyl benzene sulfonate (SDBS) was used as a surfactant to produce an electrostatic absorption effect on the surface of CNTs. This effect promoted the adherence of pyrrole monomers to CNTs. CNTs were then covered with polypyrrole by chemical polymerization. Microstructures and components of the obtained materials were characterized by transmission electron microscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy. Electrochemical performances of samples were tested by cyclic voltammetry, and galvanostatic charging/discharging by assembling the materials into electrochemical super capacitors. Results showed that pyrrole monomers could attach to the surface of CNTs via the addition of SDBS. Addition of CNTs effectively diminished the size of PPy and also improved electric and mechanical characteristics of the obtained materials. The electrochemical capacitance of the obtained porous PPy/CNTs composite was 101.1 F.g(-1) (organic electrolyte) which was about 5 times that of pristine PPy (about 19.0 F.g(-1)) and about 4 times that of pristine CNTs (25.0 F.g(-1)).
