Method of preparing diazanaphthalene biphenyl type sulphonation polyarylethernitrile electrolyte film material

Abstract

The invention discloses a preparing method of two aza naphthalene biphenyl type sulfonated polyarylether nitrile ion conductive film material, which comprises the following steps: incorporating structural element of formula 1; passing two aza naphthalene ketone biphenyl bis-phenol, dihalogen (or two nitro group) cyanobenzene, 3, 3'-two petroleum sulfonate-4, 4'- aromatic dihalogen (or two nitro group) and aromatic dihalogen (or two nitro group) as monomer; choosing alkali or salt of alkali metal or alkali earth metal; getting the product in non-proton polar solvent through high-heat copolymerization reaction; wherein R1, R2, R3, R4 maybe alkyl group, alkoxy, phenyl group, halogen atom or hydrogen atom. This invention possesses good tenacity, dig intensity, low swelling ratio, which can be used to fuel battery or energy-storage battery or film separating technology domain.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials. It relates to the preparation method of a series of phthalazine-type sulfonated polyarylether nitrile solid electrolyte membrane materials whose sulfonation degree can be precisely controlled, especially related to the technology applicable to fuel cells (PEMFC) or energy storage batteries or other related applications field of solid electrolyte separator materials. Background technique

[0002] Due to the global energy crisis and the deteriorating environment, it is urgent to develop efficient, clean and renewable energy technologies. Proton exchange membrane fuel cell (PEMFC) is the fifth-generation fuel cell developed in the 1980s. It uses hydrogen as the main fuel. It has the advantages of rapid start-up at room temperature, cleanliness, and high energy conversion efficiency, and has attracted widespread attention from researchers. Therefore, PEMFC is the most promising ideal powe...
