The invention relates to polymeric resin blends containing polyelectrolyte resins blended into a polymer or copolymer matrix. Specifically, the polyelectrolyte resins are (co)polymers without hydrolyzable groups. The matrix polymer is a tough, and highly chemical-resistant (co)polymer, preferably a fluoropolymer. The polymeric resin blend is useful for forming films, and especially films useful for MEAs for use in fuel cells.

A composition and method for controlling the attachment and growth of microbial species on the surface of a coating consisting of adding to the coating formulation polymeric nanoparticles, which have a mean particle diameter of from 1 to 50nm, linked to bioactive molecules are disclosed. The bioactive molecules are linked to the polymeric nanoparticles via either covalent or ionic bonds. The bioactive molecules may either cleave off from the polymeric nanoparticles to become the biologically active molecules or may remain linked to the polymeric nanoparticles, thus making the polymeric / bioactive molecules the biologically active entities.
A particle dispersion liquid includes: an aqueous medium; at least one of a compound represented by Formula (I) and a compound represented by Formula (II), which is dispersed in the aqueous medium; and at least one of: (i) a polymer having alkyl (meth) acrylate as a structural unit, the alkyl (meth) acrylate containing an alicyclic hydrocarbon group having a bridged bond, the polymer having an acid value ranging from 6 mgKOH/g to 100 mgKOH/g, and (ii) a polyester resin containing 20% by mass or more of a unit represented by Formula (F1) in the polyester.
