摘要
On the basis of poly(Br-acrylate-alk yne)macroinitiator with two different initiating sites(alkyne and Br),which is obtained by the RAFT homopolymerization of a new trifumctional acrylate monomer Br-acrylate-alkyne,we report here a facile synthetic approach to prepare poly(ethylene glycol)-g-poly(2,2,2-Trifluoroethyl methacrylate)(PEO-g-PFMA)hybrid dual brush polymer by one pot simultaneous ATRP polymerization and"click"reactions.With two different kinds of brashes PEO and PFMA densely distributed on the same unit along the backbone,spin-cast dun film of the hybrid dual brush polymer PEO-g-PFMA exhibited a synergistic anti-fouling property,the PEO brush endow the surface with a non-fouling characteristic while the PFMA brush exhibit fouting-release functionality with their low surface energy.Analysis by protein adsorption and cell adhesion tests provided estimates of the anti-fouling activity of hybrid dual brush polymer surfaces,which was examined to be influenced by the degree of polymerization(DP)of the backbone,the molecular weight of PEO and the PFMA brush length.With compositional heterogeneities,the hybrid dual brush polymer surfaces show considerable ann-fouling performance.
