Abstract

The invention provides a novel ferrocene derivative anion exchange membrane and a preparation method thereof. The anion exchange membrane comprises ethyl side chain type polyisatin biphenyl, butyl side chain type polyisatin biphenyl and hexyl side chain type polyisatin biphenyl according to different lengths of grafted side chains. The invention also provides a novel ferrocene derivative anion exchange membrane and a preparation method thereof. According to the method, a polyisatin biphenyl polymer is prepared by utilizing a step-by-step growth polymerization reaction catalyzed by superacid, and the anion exchange membrane containing the ferrocene derivative is prepared by virtue of a nucleophilic substitution reaction. The hydroxyl conductivity of the novel ferrocene derivative anion exchange membrane disclosed by the invention at 80 DEG C is 0.059 S / cm.

Description

technical field [0001] The invention belongs to the fields of polymer materials and anion-exchange membrane fuel cells, and in particular relates to a preparation method of a novel ferrocene derivative anion-exchange membrane. Background technique [0002] A fuel cell is an electrochemical device that converts chemical energy into electrical energy with only water as a by-product. It has become a research hotspot because of its environmental friendliness, sustainable development and huge citation potential. Anion exchange membrane is one of the core components of alkaline fuel cells, and it is also an important factor affecting the performance of fuel cells. Sex still can't meet the needs of daily use. [0003] The main factors affecting the performance of anion exchange membranes are the properties of the polymer backbone and ion transport groups. Zhu et al. (J. Mater. Chem. A, 2019, 7, 6883-6893) synthesized high molecular polymers with excellent chemical and mechanical...
