▎ 摘　　要

Polyaniline/graphene (PANI/GN) nanocomposites were fabricated via in-situ oxidative polymerization of aniline in the presence of cetyltrimethylammonium bromide (CTAB) modified graphene (CGN) in 1M hydrochloric acid (HCl) solution. The morphology and structure of PANI/GN samples were investigated by Fourier transform infrared spectrum, X-ray diffraction, ultraviolet and visible spectrum, thermogravimetric analysis, field-emission scanning microscope (FE-SEM), and transmitting electron microscopy (TEM). The conductivities of the PANI/GN nanocomposites were measured using four-probe electrical conductivity measurement. The results indicated that the GN sheets disperse into the form of monolayer or stack few layers in PANI matrix. The GN sheets serve as a support material for PANI particles and the structure of GN covered with PANI nanoparticles were confirmed by FE-SEM and TEM. The electrical conductivities of the PANI/GN samples have been improved compared with pure PANI prepared in the similar condition. (C) 2014 Society of Plastics Engineers
