WETTABILITY OF HIGHLY FLUORINATED POLYMER-COATINGS

Wettability of a linear polymer is a function of backbone structure, side-chain substitution, and fluorination. For a polymer to be suitable as a thin coating, a convenient method of application is mandatory to insure continuity and adherence to the respective substrate. Wetting properties of highly fluorinated ethylenic and methacrylic polymers are examined. The latter have proven to be effective barrier films for the prevention of liquid spreading in certain applications, and the effect of solvents on the wetting and adhesion of such films and on their stability with a variety of liquids are discussed. © 1978, Taylor & Francis Group, LLC.
