Study of High Performance Sulfonated Polyether Ether Ketone Composite Electrolyte Membranes. [PDF]
Polymers (Basel), 2019 In this study, high performance composite electrolyte membranes were prepared from polyether ether ketone polymeric material. An initial sulfonation reaction improved the membrane hydrophilicity and its water absorbability and thus enhanced the ionic conductivity in electrochemical cells. Protonic conductivity was improved from 10−4 to 10−2 S cm−1 with
