Poly(N-vinylpyrrolidone)-modified poly(dimethylsiloxane) elastomers as anti-biofouling materials

► A new chlorosilane surface-initiated atom transfer radical polymerization (SI-ATRP) initiator was synthesized. ► Poly(N-vinylpyrrolidone) (PVP)-modified poly(dimethylsiloxane) (PDMS) elastomer surfaces were first prepared by SI-ATRP. ► The PVP-modified PDMS surfaces possessed significantly anti-fouling property.
