摘要

Aligned carbon nanombes(ACNTs) were modified with polypyrrole(PPy) via electropolymerization.Because of the large specific surface area and excellent electrical conductivity of ACNTs,continuous electropolymerization was able to be carried out,forming a thick PPy coating on the ACNTs.The resulting nanocomposite possessed a core-shell structure with ACNTs as the core PPy as the shell,and nanoparticles of PPy on the top,and displayed high performance supercapacitance properties.
