M., Zhou J., Chemcial Industry and Engineering Progress, 2009, 28, 429-436 Key words: Carboxybetaine ester, Hydrolysis, Function switch, Polymer brush, Surface property When DH>50%, the hydrolyzed Glass-PCBMA-1C2 surface exhibits good resistance of protein adsorption and platelet adhesion. Compared with Glass-PCBMA-1C2 surface, with the increase of DH, the protein adsorption of BSA are reduced by 3%, 76%, 93% and 96%, and that of Fg are reduced by 11%, 45%, 90% and 96%, respectively. The results show that when the concentrations of ammonium hydroxide are 0.1, 0.2, 0.3 and 0.4 mol/L, the degrees of hydrolysis(DH) of terminal ester of CBMA-1C2 monomer are 6%, 43%, 56% and almost 100%, respectively. The protein adsorption and platelet adhesion experiments were used to evaluate the interaction between the material surface and the biomolecules. X-ray photoelectron spectroscopy(XPS) and water contact angle were used to monitor the chemical changes and hydrophilicity, respectively. The hydrolysis of PCBMA-1C2 modified surface was evaluated by studying the hydrolysis behavior of CBMA-1C2 monomer under different ammonium hydroxide concentrations. A hydrolysable cationic polycarboxybetaine ester polymer brush(PCBMA-1C2) was fabricated by photografting method with surface-coupled tertiary amine as hetergenous hydrogen donor and benzophenone(BP) as photosensitizer.
