High-Performance Semicrystalline Poly(ether ketone)-Based Proton Exchange Membrane.

Sinan Feng et al.

ACS applied materials & interfaces, 9(29), 24527-24537 (2017-07-07)

A novel semicrystalline poly(ether ketone) (PEK)-based proton exchange membrane (semi-SPEK-x) has been developed. Through a one-step sulfonation and hydrolysis, a poly(ether ketimine) precursor transforms into PEK and ion-conducting groups are introduced. With an ion-exchange capacity ranging from 1.49 to 2.00
