Abstract
AbstractIn this study, the copolymerization of sulfobetaine methacrylate (SBMA) and acrylic acid (AA) was carried out by atmospheric pressure plasma jet (APPJ) treatment. By applying APPJ on the precursor solutions, OH radicals and the other reactive species were generated to induce the polymerization processes in solutions. The molecular weight and composition of the resultant poly(SBMA‐co‐AA) can be easily modulated by varying the plasma parameters including treatment time and applied power. The anti‐biofouling effects of the resultant poly(SBMA‐co‐AA) against biomolecules including lysozyme, bovine serum albumin (BSA), and L‐929 mouse fibroblast cells revealed excellent fouling resistance. This study demonstrated that APPJ‐assisted copolymerization is a chemical initiator free process and can provide a simpler alternative route for the preparation of copolymers with designated compositions and advantageous functions.
