More and more attention has been paid to the research of membrane materials

with the development of membrane separation

proton exchange membrane fuel cell

and flow battery for energy storage.Poly(phthalazinone ether)s are a kind of membrane materials with excellent performance.Due to the polymer main chains containing aromatic heterocyclic twisted non-coplanar structure

poly (phthalazinone ether)s show good chemical stability

good themal stability

and can be soluble in common membranes casting solvents such as N-methy-l2-pyrrolidone and N

N-dimethylacetamide.Poly (phthalazinone ether)s show promising applications for thermally stable separation membranes and ion exchange membranes.In this paper

the development of poly (phthalazinone ether) s membrane materials and their applications for gas separation membranes

liquid separation membranes

and ion exchange membranes for energy field were reviewed.
