Abstract: Crosslinked sulfonated triblock copolymers exhibit lower methanol permeability and good physical strength relative to the perfluorinated proton conductive membranes typically used in Direct Methanol Fuel Cells. Examples of triblock copolymers that can be used as fuel cell membranes include SEBS, SIBS, and SEPS. The chemically cross-linked and sulfonated SIBS, SEBS, and SEPS exhibit lower swelling and tolerate higher sulfonation levels than the un-cross-linked counterparts. These copolymers are easily sulfonated using known procedures and can be manufactured at a fraction of the cost of the typical perfluorinated proton conductive membranes.

Abstract: A fuel cell including an MEA sealed by a multi-block copolymer gasket is disclosed. The self-assembling, nanophase-separated polymer exhibits higher corrosion resistance relative to typical silicone gaskets while providing a better seal of the MEA to the fuel cell housing than PTFE.

Abstract: A water-resistant composite paper, suitable for use as a loudspeaker component, is made from a composition including hydrophobic fibers, stiffening fibers that retain stiffness when wet, and fluorocarbon. In some examples, fibrillated acrylic fibers and glass fibers are used.

Abstract: A membrane electrode assembly includes a polymer electrolyte membrane sandwiched between an anode catalyst layer and a cathode catalyst layer. The area of the anode catalyst layer is less than the area of the cathode catalyst layer. The larger cathode catalyst layer is believed to increase collection of protons from the anode reaction, reduce the corrosive effect of the highly acidic solvated protons in the polymer electrolyte membrane, and allow for small misalignments of the layers during construction of the assembly.

Abstract: A photographic film with a polymeric acid-reacting neutralizing layer comprising a half ester of isobutylene/maleic anhydride copolymer is provided herein. This polymeric acid-reacting neutralizing layer is used to attenuate a photographic film's development process, which is effective under alkali conditions, by lowering the pH of the alkaline processing composition.

Abstract: An image-receiving element for use in photographic and photothermographic dirrufsion transfer film units of the type where the image-receiving element is designed to be removed, or “peeled-apart” from a photosensitive element following exposure and photographic processing. The present image-receiving element comprises, in sequence, a support, an image-receiving layer and a strip-coat layer which serves to facilitate separation of the image-receiving element from the photosensitive element after photographic processing. The strip-coat layer comprises a cationic homopolymer or a copolymer of an acrylate with a quarternary salt functional group. The strip coat provides a glossy image after photographic processing.
