Molecular Aggregation Structure and Surface Properties of Biomimetic Catechol-Bearing Poly[2-(perfluorooctyl)ethyl acrylate] and Its Application to Superamphiphobic Coatings.

ABSTRACT: The molecular aggregation structure and surface properties of a catechol-bearing fluoropolymer, P(FAC₈-co-DOPAm), which was synthesized by conventional radical copolymerization of 2-(perfluorooctyl)ethyl acrylate (FAC₈) and N-(3,4-dihydroxyphenethyl)acrylamide (DOPAm), and its application to the superamphiphobic surfaces are presented. The crystallinity of P(FAC₈-co-DOPAm) was lower than that of poly[2-(perfluorooctyl)ethyl acrylate] (PFAC₈). The perfluoroalkyl (R_f) groups were ordered on the surface with CF₃ terminals exposed to air, and the R_f ordering was influenced by thermal history: the thermally annealed film exhibited higher R_f ordering than the unannealed one. The surface f
