摘要：
Surfactant bilayers adsorbed on TS-l zeolite were used as templates to produce colloidal nanocomposites with a polypyrrole(Ppy) shell. The adsorbed surfactant was cetylpyridinium chloride, and it plays a critical role for attaining both the colloidal stability of the nanocomposites and an enhanced conductivity of the Ppy sheath on the TS-1 core. The observed contact conductivity of the nanocomposites was 5 S/cm for a sample with 8 wt % of Ppy incorporation while bulk Ppy powder had a contact conductivity of 0.03 S/cm.
