A system and method for an energy storing electrical device includes a first conductive electrode, a second conductive electrode, an electrolyte disposed between the first conductive electrode and a second conductive electrode, each electrode further comprising an integrated first layer and a second layer, and; wherein the second layer comprises a substrate, the substrate comprising a textile portion or a polymer portion and a conductive layer formed by a noble metal disposed on and attached to the substrate.

Described herein are methods for the surface deposition of polyionic species on a substrate surface. This deposition process can be triggered facilely by oxidizing organometallic species present on the surface of the substrate. This approach is quite general, affording quantitative deposition of polyionic species with a wide range of chemical identities (e.g., synthetic polymers, peptides and DNA) and molecular weights. This approach is in addition suitable for surface deposition of several types of functional materials, including proteins (antibodies), nanomaterials, colloids, lipid vesicles, among others.

Cathodic electrocoating composition with improved edge protection and coating appearance are provided. An exemplary cathodic electrocoating composition includes an aqueous carrier, a film forming binder dispersed in the carrier and including an epoxy-amine adduct and a blocked polyisocyanate crosslinking agent; a pigment paste; a water-soluble cellulose ether; and a cationic microgel dispersion which is prepared by a process comprising dispersing in aqueous medium a mixture of a cationic polyepoxide-amine reaction product which contains amine groups selected from the group consisting of primary amine groups, secondary amine groups, and mixtures thereof and a polyepoxide crosslinking agent and heating the mixture to a temperature sufficient to crosslink the mixture to form the cationic microgel dispersion. The water-soluble cellulose ether may be hydroxyethyl cellulose.
