This investigation studied the transport properties of several fluorinated sulfonated membranes for direct methanol fuel cell applications. First, Nafion® membranes were processed with supercritical fluid (SCF) CO2 and ...

Nafion® membranes commonly used in direct methanol fuel cells (DMFC), are tipically limited by high methanol permeability (also known as the cross-over limitation). These membranes have phase segregated sulfonated ionic ...

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 ...

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, ...

In this study, poly (styrene-isobutylene-styrene) (SIBS) was characterized using thermogravimetric analysis. The thermal behavior of three types of SIBS, with different average number molecular weight, Mn , and polystyrene ...

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 ...

This study describes the synthesis and characterization of sulfonated poly(styreneisobutylene- styrene) (SIBS) polymer nanocomposite membranes, which show antibacterial properties useful for the inactivation of Enterococci ...

Organic solar cells are a very promising technology for use in the renewable energy field. Band gap measurements on liquid phase for different polymers were studied, and the possible radiation harvest and reasoning for ...

The rapid growth of the global population, the industrialization and environmental problems caused by global warming have made it necessary to implement advanced water purification techniques capable of fulfilling the ...
