Fluorocarbon Minimization Via Semifluorinated Copolymer Films by Combining Spin Coating and Ring-Opening Metathesis Polymerization.

ABSTRACT: Per- and polyfluoroalkyl substances (PFAS) are ubiquitous in society largely due to their unique surface properties, but significant health concerns associated with these substances underscore the need for PFAS reduction strategies. We report a method to substantially reduce the amount of PFAS, solvent, and time needed to synthesize a low surface energy polymer film through the copolymerization of norbornene (NB) with 5-(perfluoro-n-alkyl)norbornenes (NBFn) in a single process that combines spin coating with ring-opening metathesis polymerization (scROMP). The unique scROMP approach efficiently integrates polymer film synthesis and deposition into one rapid process, converting monomer into polymer films in <2 min with <1 mL of solvent for a 36 cm² film.
