▎ 摘  要

Here, we report a fast fabrication process of nanocomposites with better electrical properties by intermixing graphene oxide (GO) and low ammonia natural rubber latex (NRL) polymer via the one-step method (similar to x 10(-5) to x 10(-7) S cm(-1)). In comparison, the nanocomposite synthesized by the two-step method demonstrated lower electrical properties which were calculated to be x 10(-7) S cm(-1). Obviously, the increase in the electrolyte concentrations from 0.01 to 0.1 M SDS did not influenced the electrical conductivity which means the fabrication process also played a role in a successful dispersion of GO in NRL polymer. The electrical testing was carried out by four-point probe instrument and cyclic voltammograms in the range of 0-1 V were measured at various scan rates for all samples using a computerized potentiostat-galvanostat equipped with Gamry software (Gamry potentiostat series-G750, USA). Among all nanocomposite samples, 0.01 M SDS-GO/NRL nanocomposite synthesized via one-step method successfully showed higher capacitance performance which found to be 107 F g(-1).
