Surface Structure and Protein Resistance of PMMA/PS Copolymer Coatings

Abstract:

PMMA/PS copolymers were synthesized by radical polymerization techniques. And the 1H NMR results illustrate that the molar contents of PMMA are respectively 19%, 53%, 69% and 84%. The coatings of those PMMA/PS copolymers were prepared by spin-coating. The surface structures and protein resistance of copolymer coatings were investigated respectively by AFM and BSA absorption experiment. It is showed that the copolymer coating surfaces have micro-phase separation structure. Furthermore, with the increase in the PMMA content, the surface pattern changes from interpenetration network pattern to island structure that the PMMA-rich phase surrounded by the PS-rich phase. In addition, all coatings prepared in this study, especially the coating with PMMA content of 69%, have good resistance to BSA protein.
