AFM images on various surfaces.

Notes: (A) Pristine PDMS, (B) p (DMAEMA⁺), (C) p (DMAEMA⁺-co-0.10 MPC), (D) p (DMAEMA⁺-co-0.25 MPC), and (E) p (DMAEMA⁺-co-0.50 MPC). p (DMAEMA⁺-coMPC) copolymer brush coatings were synthesized by RAFT polymerization in DMAEMA⁺/MPC monomer solution in ethanol in the mass ratio of 1:0, 1:0.1, 1:0.25, and 1:0.5 and the obtained samples were named as P1-0, P1-0.1, P1-0.25 and P1-0.5, respectively.

Abbreviations: AFM, atomic force microscopy; PDMS, poly(dimethyl siloxane); p (DMAEMA⁺-co-MPC), (2-(dimethylamino)-ethyl methacrylate-co-2-methacryloyloxyethyl phosphorylcholine); MPC, 2-methacryloyloxyethyl phosphorylcholine; DMAEMA, 2-(dimethylamino)-ethyl methacrylate; RAFT, reversible addition–fragmentation chain transfer.
