摘要: Mesostructured polyaniline/single-wall carbon nanotube (PAni/SWCNT) composite film has been prepared through electrochemical polymerization/degradation processing. The microstructures of the films are observed before and after electro-degradation. Initial twisty SWCNT bundles broken down linked by polymerization PAni. Both crystalline disordered PAni regions coexist in PAni/SWCNT nanowires. gradually dissolved while basically preserved formation mechanism with special construction proposed. In addition, cyclic voltammetry measurements demonstrate that electroactive performance is enhanced It found specific capacitance electro-degraded reaches up to 848.7 F/g, more than twice over untreated film, which ascribed its profitable charge accessible interface increased available regions.
