- Abstract
Amphiphilic fluorocopolymers P(MMA)-co-P(PEGMA)-co-P(DFHM) are prepared via ATRP by hydrophilic poly(ethylene glycol) methyl ether methacrylate (PEGMA), hydrophobic dodecafluorohrptyl methacrylate (DFHM) and methyl methacrylate (MMA). The self-assembled surface is characterized by chemical composition, morphology, wettability and the protein adsorption resistance to bovine serum albumin (BSA). The hemispherical micelles are composed of light semisphere P(MMA)-co-P(PEGMA) and dark semisphere P(DFHM) in CHCl3. With the diameters of P(MMA)-co-P(PEGMA)-co-P(DFHM) micelles increased by the decreasing of fluorine content in MMA/PEGMA/DFHM, as 180nm (14/1/1.2), 230nm (20/1/0.8) and 280nm (14/1/0.4), the surface roughness of films is accordingly reduced as 0.343nm, 0.754nm and 1.01nm. During the film-forming, the fluoride segments migrate onto the film surface to contain rounded-hills or cylindrical-shape distributed morphology. Much high hexadecane contact angle (54.73°-55.41°) and water contact angle (122.74°) of film surfaces are able to indicate the sufficient hydrophilic/hydrophobic surface, but the film by much contain PEGMA content shows an excellent behavior of BSA protein-resistance ( f=-15.0Hz). When the MMA/PEGMA/DFHM is controlled at 20/1/0.8 and 14/1/0.4, the amphiphilic fluorocopolymers obtain much high Td (203.4°C).
