摘要
Composites based on poly(diphenylamine)/graphene oxide and gold were prepared by chemical oxidative polymerization using in situ dispersion polymerization technology. In the polymerization, diphenylamine was polymerized in the presence of dispersed graphene oxide in sulfuric acid with ammonium persulfate as an initiator, and HAuCl4 was simultaneously reduced by hydrazine. The gold nanoparticles were well dispersed in polymer-graphene oxide layer sheets. The morphology and nanostructure of the composites were examined by transmission electron microscopy. X-ray diffraction, Fourier transforms infrared, and UV-visible spectroscopies were used to characterize the composites, and revealed the interactions among the components in the composites.
