The aim of this work is to improve the supercapacitor performance of polyaniline (PANI). Polyaniline nano fibres are incorporated into graphene oxide (GO) layers by interfacial polymerization pathway, wherein PANI fibres are intercalated into GO layers and also cover the GO. PANI–GO hybrid composite is obtained in semi-crystalline form with good conductivity (1.7 S cm?). The specific capacitance for PANI–GO (365 F g?) is found to be higher than PANI (280 F g?). At the energy density of 15 W h kg?, the power density of PANI–GO (632 W kg?) is higher than PANI (283 W kg?). Keywords Polyaniline–graphene oxide Supercapacitor Interfacial polymerization Morphology
