Problems solved by technology

[0004] At present, it is divided into: perfluorosulfonic acid type proton exchange membrane; nafion recast membrane; non-fluoropolymer proton exchange membrane; new composite proton exchange membrane, etc.; Compared with perfluorosulfonic acid Nafion recast membrane, there is a relatively large gap. Therefore, how to improve the conductivity of polyphenylene ether proton membrane and improve its comprehensive performance is very necessary.

Abstract

The invention discloses a brominated embedded polyphenyl ether proton membrane. The brominated embedded polyphenyl ether proton membrane is prepared from the following raw materials in parts by weight: 0.8-1 parts of octyl isothiazolinone, 7-10 parts of esterified modified zirconium phosphate, 0.1-0.4 parts of brominated hexadecyl trimethylimidazole, 50-70 parts of polyphenyl ether, 3-4 parts of chlorosulfonic acid, 0.1-0.2 parts of dibasic lead phosphate and 1-2 parts of silane coupling agent. Surface modification of zirconium phosphate is performed firstly, and then embedding of brominated hexadecyl trimethylimidazole is carried out, so that embedding stability is improved effectively, and the antibacterial activity of the finished product of the proton membrane is improved.

Description

technical field [0001] The invention belongs to the field of proton membranes, and in particular relates to a brominated chimeric polyphenylene ether proton membrane and a preparation method thereof. Background technique [0002] The proton exchange membrane is the core component of PEMFC, and PEM is different from the diaphragm used in general chemical power sources. Proton exchange membrane fuel cells have become the most competitive clean alternative power source for gasoline internal combustion engines. The materials used as PEM should meet the following conditions: good proton conductivity, small electroosmosis of water molecules in the membrane, and gas in the membrane. The permeability in the medium is as small as possible, the electrochemical stability is good, the dry-wet conversion performance is good, it has certain mechanical strength, good processability, and the price is reasonable; [0003] Proton exchange membrane fuel cells have become the most competitive ...
