    Nanomatrix channel to prepare high-proton-conductive polymer electrolyte was formed by graft copolymerization of styrene onto deproteinized natural rubber (DPNR) followed by sulfonation with chlorosulfuric acid. The resulting sulfonated DPNR-graft-PS (SDPNR-graft-PS) was characterized by solid state 13C CP/MAS NMR spectroscopy, elemental analysis, and transmission electron microscopy. High proton conductivity of about 0.1 S/cm was accomplished with continuous nanomatrix channel of sulfonated polystyrene. Arrhenius plot for proton conductivity of SDPNR-graft-PS makes possible to consider that the proton-transport in SDPNR-graft-PS with nanomatrix channel, nafion 117 and sulfonated polystyrene occurs in a manner of Grotthus mechanism, in which the proton jump from one sulfonic acid to the other takes place.
