The invention relates to polymer powders, preferably fluoropolymer powders such as polyvinylidene fluoride (such as Kynar resins from Arkema Inc.), polyvinyl fluoride, and poly-ethylene-co-chlorotrifluoroethylene, useful for a high-solids liquid slurry. The PVDF has a narrow average particle size of from 20 to 100 microns, with less than 20 weight percent of particles outside this range. This powder can be used to form slurries having from 30 to 60 weight percent solids, the liquid slurries formed being free-flowing. The free-flowing slurries are useful in forming membranes in a thermally induced phase separation (TIPS) process.

Disclosed herein is a method of manufacturing a membrane electrode assembly (MEA) including directly depositing a liquid suspension containing a platinum precursor onto an ionically conductive membrane (e.g., proton-exchange membrane) that, when the platinum precursor deposit layer is reduced, provides a layer that will scavenge hydrogen that has diffused back through the membrane due to cell stack pressure differential.

A mechanochromic system comprising a first inorganic/polymer composite layer; and a first elastomer layer bonded to the composite layer to form a composite/elastomer assembly, methods of making, and methods of use thereof are provided.

The present invention relates to a photocatalytic coating film composition and method for producing thereof. More specifically, it relates to an acidic anti-mould and anti-fungal photocatalytic coating film formed by the decomposition and evaporation of the volatile organic base from the photocatalytic coating composition after the application and the drying on substrate. The photocatalytic coating liquid composition consisting of a strong acidic nature of Nafion with pH<2 as an indispensable binder resin; a volatile organic base to neutralize the acidic binder resin temporarily and photocatalysts to generate strong oxidizing compounds which decompose harmful organic compounds and also to provide protection for the acidic environment by decomposing neutralizing chemicals from outside.
