▎ 摘  要

In this work, the graphene oxide/mesoporous silica/polyaniline (GO/mSiO(2)/PANI) composite was synthesized via in-situ polymerization method. PANI was introduced into the mesoporous channels of mSiO(2), followed by dispersion of PANI-containing mSiO(2) into the interlayers of GO sheets. The morphology, functional groups, and crystalline phases of GO/mSiO(2)/PANI composite were scrutinized. The characterization proved the successful incorporation of the PANI nanofibers into mSiO(2) and the uniform intercalation of PANI-embedding mSiO(2) between the GO sheets. Such unique structure provides the GO/mSiO(2)/PANI composite electrode with an excellent capacitance up to 1218.4 F g(-1) and 92.5% capacitive retention after 1000 cycles. GO/mSiO(2)/PANI composite could be an excellent electrode material for supercapacitor application.
