Abstract

The invention relates to a preparation method of an alcohol resisting type polyarylether electrolyte film material, and belongs to the technical field of an electrolytic film material. Collagen and polyvinyl alcohol are mixed to be subjected to hydrolysis to form amino acid to be grafted to the surface of a polyvinyl alcohol material; by virtue of amino modification of polyvinyl alcohol and sulfonic acid group modification processing, a macromolecule crosslinking agent with the sulfonic acid group is introduced; next, through thermal treatment, the sulfonic acid group and amino are subjected to a cross-linking reaction to prepare an amino-containing sulfonated polyarylether ketone sulfone / sulfonated polyvinyl alcohol crosslinking film; sulfonated polyvinyl alcohol has high alcohol resisting performance, and meanwhile, the sulfonic acid group and amino can exist in an acid alkali pair form by virtue of an acid alkali effect therebetween, so that proton transmission sites are provided for protons and proton conduction is promoted; and in addition, by virtue of the formed crosslinking network structure, permeation of methyl alcohol can be suppressed effectively, and the prepared electrolyte film material can be excellent in compact structure.

Description

technical field [0001] The invention relates to a method for preparing an alcohol-resisting polyarylether electrolyte membrane material, and belongs to the technical field of electrolytic membrane materials. Background technique [0002] For fuel cells that use polymer membranes as electrolytes to transmit ions and isolate fuels and oxidants, the core component is the polymer electrolyte membrane. Polymer electrolyte membrane materials can be roughly divided into two categories: proton exchange membrane, PEM) and anion exchange membrane. The important role of this membrane is reflected in the fact that its comprehensive performance directly affects the various efficiency and performance indicators of the fuel cell. As the core component of the fuel cell, it plays a very important role. It not only has excellent ability to block fuel and oxidant, but also has good ion conductivity, so that the fuel cell can work normally. Then the polymer electrolyte membrane material with ...
