Abstract
- Poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) and poly(N,N′-dimethyl-(methylmethacryloyl ethyl) ammonium propanesulfonate) (PDMAPS) were grafted on polyurethane (PU) surfaces by one-pot ATRP and click chemistry in order to improve the lubricating and antifouling properties. The successful grafting of PMPC and PDMAPS was confirmed by X-ray photoelectron spectroscopy. The immobilization of zwitterionic polymer brushes significantly improved the surface hydrophilicity and lubricating property of PU. In addition, the protein and bacteria adsorption on the modified PU surfaces were reduced greatly due to the presence of hydrated layer around the zwitterionic groups. The present surface modification approach was simple and versatile for functionalization of polymer surfaces.
