Investigation on the wettability properties of thin films of methacrylic polymers with partially fluorinated side chains

Abstract

SUMMARY Thin films of methacrylic polymers, obtained by copolymerization of perfluorodecyl-and 2-ethylhexyl methacrylate, were prepared by spin coating or by the Langmuir-Blodgett (LB) technique. The permeability to water of these materials was studied by means of the attenuated total reflection (ATR) technique, revealing the strong dependence of the swelling phenomenon on the films' surface composition and structural order. The presence of polar groups on the fildair interface facilitates the wetting of the thin films.

Solubility, Emulsification and Surface Properties of Maleic Anhydride, Perfluorooctyl and Alkyl Meth-Acrylate Terpolymers

“…However, the basic idea of forming amphiphilic terpolymer consisting of maleic anhydride and long aliphatic side chain methacrylate has been reported before [ 9 ], and a very limited number of publications are found reporting successful self-emulsification of fluorinated polymers in water [ 1 ] The creation of water-soluble or water dispersible perfluoroalkyl side chain copolymers is supported by the use of maleic anhydride as a comonomer. Hydrolysis of the succinic anhydride rings in the polymer backbone yields hydrophilic carboxylates [ 10 ] that additionally improve the adhesion to any substrate that may interact with carboxylic acid or carboxylate groups [ 11 ]. This manuscript presents investigations on the solubility, emulsification and the surface properties of coatings prepared from perfluorinated copolymers of the general structure presented in Scheme 1 .…”

Gradient Structure and Surface Property of Fluorinated Polyacrylate and Polyurethane Latex Blend Films

“…[1][2][3][4] However, in most cases poor adhesion and relatively expensive to produce may circumscribe their use. It is one of the important topics of the research on how to make the fluorinated components play a better role and how to increase the bond strength of the material on the premise of maintaining good surface properties of materials.…”
