Abstract: The present invention relates to a coating composition comprising a fluoropolymer and a dopamine derivative. Further, the present invention relates to a process for coating a substrate, comprising the steps of (a) providing a coating composition comprising a fluoropolymer, a dopamine derivative and a solvent; (b) locating the coating composition on a substrate; (c) heating the coated substrate to remove the solvent; and (d) optionally pressing the heated coated substrate against another material surface to bond these to each other. The present coating composition allows the bonding of fluoropolymers through a process that eliminates the need for mechanical keying and hazardous or costly etching processes.

Abstract: In one aspect, compositions comprising copper-silica (Cu—SiO2) core-shell nanoparticles are described herein. The core-shell nanoparticles comprise copper (Cu) core components and silica (SiO2) shell components encapsulating the core components. In some embodiments, the nanoparticle compositions comprise a continuous aqueous phase and a population of copper-silica (Cu—SiO2) core-shell nanoparticles dispersed in the aqueous phase.
