Novel sulfonated ether based block copolymer ionomers as proton exchange membranes for fuel cells applications
This investigation studied the morphology, hydration, and transport properties of different membranes for direct methanol fuel cell (DMFC) applications. First, sulfonated poly(ether ether ketone) (SPEEK) membranes were ...
Functionalization and characterization of Sulfonated Poly (Styrene-Isobutylene-Styrene) membranes for fuel cells and specialty separation applications
In this study, the transport properties of poly(styrene-isobutylene-styrene) (SIBS) block copolymer were determined as a function of sulfonation level (0-94.9 %), counter ion substitution (Ba+2, Ca+2, Mg+2, Mn+2, Cu+2, ...
Poly(styrene-isobutylene-styrene) nanocomposite membranes for fuel cell devices and specialty separation applications
Ionic domains were incorporate into sulfonated poly(styrene–isobutylene–styrene) (SO3H SIBS) in an effort to improve the transport properties of the functionalized aromatic block copolymer. The resulting polymer nanocomposite ...
