It is well known that a segment of a multicomponent polymeric system such as copolymer selectively adsorb and orient to the surface of the system so as to minimize interfacial free energy in response to an environmental media. Surface molecular mobility of perfluorooctyl (PFO) group of acrylic copolymers, having PFO as a side chain, was investigated via dynamic contact angle and X.p.s. For all copolymers, more fluorine was detected than calculated amount from composition via X.p.s. In addition, the shallower sampling depth of X.p.s., the more fluorine was detected. These sample polymers exhibited a relatively large contact angle hysteresis. Advancing contact angle theta(A) for copolymers increased with an increase in PFO content. Receding contact angles were largely influenced by polar group of copolymers.
