| Abstract: | Silica particles were first modified by silane coupling agent aminopropyltriathoxy, then PPy/SiO2 nanocomposites were prepared by chemical polymerization. In the text, the structural characteriation and action mechnism of coupling agent were discribed. The research results about conductivity ofnanocomposites indicate that the adding of APS made the increasing of PPy content, conductivity and stability of composite materials. The conductivity of PPy/APS-SiO2 is 38.46 S/cm, which is the highest among those have been reported. |
