▎ 摘　　要

An insulating polymer, radiation vulcanization natural of rubber latex (RVNRL), was successfully converted into electrically conductive nanocomposite by the addition of reduced graphene oxide (rGO) assisted by sodium 1,4-bis(neopentyloxy)-3-(neopentyloxycarbonyl)-1,4-dioxobutane-2-sulfonate (TC14) surfactant. The starting material, graphene oxide (GO), was initially synthesized by electrochemical exfoliation assisted by TC14 surfactant. Then, GO/RVNRL nanocomposite was fabricated by latex technology. For rGO/RVNRL nanocomposite, the synthesized GO was further reduced to rGO using hydrazine hydrate and showed electrical enhancement up to 1.32 x 10(-3) S cm(-1) compared with GO when composited with RVNRL (8.64 x 10(-4) S cm(-1)). For comparison, rGO/RVNRL nanocomposite assisted by the commercially available surfactant sodium dodecyl sulfate was prepared, and its electrical conductivity was found to be 1.79 x 10(-5) S cm(-1), which was several orders of magnitude lower than those of GO/RVNRL and rGO/RVNRL nanocomposites prepared with TC14 surfactant. C-V measurements taken for TC14-rGO/RVNRL and TC14-GO/RVNRL nanocomposites showed specific capacitances of 95 and 63 F g(-1), respectively. The structural properties of nanocomposites were characterized using FESEM, HRTEM, UV-Vis, micro-Raman, XRD, FT-IR spectroscopy, and TGA studies. This study was the first to report on the success of converting the insulator polymer RVNRL into a conductive nanocomposite assisted by TC14 surfactant. The nanocomposite can be a new electrode material for supercapacitor application.
