This talk will highlight a variety of functional copolymers that can be permanently grafted to any substrate containing C–H bonds to form a durable polymeric film within 1 minute. The general strategy for polymer design includes copolymers of: (1) a functional component (anti-ice, anti-foul, antimicrobial, superlubricating, oleophobic, etc.), (2) a wetting agent for improved surface/substrate uniformity, and (3) a benzophenone moiety that, under mild UV irradiation, generates a densely cross-linked network with covalent attachment to a variety of substrates, including plastics, fabrics, and alkyl-modified glass surfaces. Through molecular design of the chromophore, the kinetics of crosslinking were observed to be one order of magnitude faster than that of previously reported benzophenone-associated cross-linkers, which makes the photochemical crosslinking more attractive for industrial coating applications. In this talk, we demonstrate functional coatings that have excellent durability that are used in a wide variety of applications.
