Abstract：Comb-type copolymer of poly(maleic anhydride-dodecene styrene)(MASC) was synthesized.A hybrid composite of MASC encapsulating SiO2 nano-particles was prepared based on simple milling.The comb-polymer MASC was characterized by 1HNMR and FTIR.The polymer hybrid MASC-SiO2 was characterized by FTIR,TG,contact angle,TEM and transparency measurement.The results show that the maximum grafting ratios is approximately 21.05%.When the mass ratio of MASC and SiO2is 1∶1,its static contact angle reaches 140°.Adjusting the mass ratio of copolymer and SiO2nano-particles makes the hybrid particles have good dispersibility in organic solvents with different polarities.
