Abstract

A sulfonated atactic high polymer containing double biazanaphthone is prepared through copolymerizing reaction between biphenol containing double biazanaphthone, sulfonated dihalgoen and dihalogen in the polar nojn-protonic solvent under the action of potassium carbonate. It can be used to prepare the proton exchange membrane with low cost, and high mechanical strength, hydroscopicity, stability and proton exchange capacity.

Description

technical field [0001] The invention relates to a kind of random sulfonated high polymer containing bisdiazinone and its synthesis and application. technical background [0002] With the continuous consumption and depletion of conventional energy sources, and also based on concerns about the continuous deterioration of the environment, researchers and developers from all over the world are turning their attention to more efficient and cleaner use of energy research. Fuel cells have the advantages of high energy conversion efficiency (40-60%), no pollution, and no noise, and will become the preferred energy supply method in the 21st century. At present, the fuel cell has been developed to the fifth generation, that is, the Proton Exchange Membrane Fuel Cell (PEMFC). In addition to the advantages of the general fuel cell, it is also portable, can be quickly started at room temperature, and has no electrolysis. Liquid loss, long life, high specific power and specific energy. ...
