Fabrication of Polyaniline Silica Nanotubes and Closed Polyaniline Nanotubes Using a Template of Silica Nanotube

摘要

Polyaniline silica nanotubes (PANI@SNT) were prepared by in situ polymerization of anilinium ion adsorbed on the surface of silica nanotubes (SNT),which acted as a template.After polymerization,the silica templates were intensively removed with HF solution to give closed polyaniline nanotubes (PANI-NT).Interestingly,the PANI@SNT showed pH-respon-sive redox reversibility.
