Abstract
A crosslinked nano-inorganic particle/polymer electrolyte membrane composed of a polymer film substrate, graft molecular chains bound to the backbone skeleton of the polymer film substrate and comprising a vinyl monomer graft-polymerized, sulfonic groups bound to the graft molecular chains, and an inorganic material as nano-scale particles uniformly dispersed within a crosslinked structure ascribed to the backbone skeleton of the polymer film substrate and the graft molecular chains, wherein the backbone skeleton of the polymer film substrate, the graft molecular chains, and the nano-inorganic particles mutually construct a crosslinked structure.
