Atom transfer radical polymerization(ATRP)has been employed for the synthesis of a novel fluorinated amphiphlic triblock copolymer PEG-b-PS-b-PFHEM for anti-fouling coatings.The macroinitiator based on poly(ethylene oxide)monomethyl ether was used to prepare an amphiphilic diblock copolymer PEG-b-PSt,which was then utilized to initiate the ATRP of fluorinated monomer perfluorohexylethyl acrylate (FHEA),resulting in an amphiphilic tribloek copolymer.These copolymers were characterized by means of 1H NMR and GPC.The arnphiphilie triblock copolymer surface composes of fluorinated and PEGylated blocks,and the fluorinated surface has critical surface energy,while the PEGylated surface is expected to have a relatively low inteffacial energy when in contact with water.Microphase-separation of both blocks could take place and result in the reduction of protein adsorption and cell adhesion.The amphiphilic fluoropolymer has the potential application as excellent antifouling coatings and antifouling membranes.
