Sulfonation degree effect on ion-conducting SPEEK-titanium oxide membranes properties
Polímeros, 2017 Polymeric membranes were developed using a SPEEK (sulfonated poly(ether ether ketone)) polymer matrix, containing titanium oxide (TiO2) (incorporated by sol-gel method). SPEEK with different sulfonation degrees (SD): 63% and 50% were used.
