Stimuli responsive polymer surface coating for antifouling effect |
| 초록 |
pH and DTT responsive surface with highly fouling resistance is reported using poly[(hydroxyethylmethacrylate-g-benzoic acid)-co-(dimethylaminoethyl methacrylate-g-2-chloro-3', 4'-dihydroxyacetophenone)] [poly[(HEMA-BA)-co-(DMAEMA-CCDP), P1] as coating material. After that, redox responsive disulfide containing amine end capped Pluronic [Plu-S-S-NH2, P2] was introduced to P1 via formation benzoic imine bond where polyethylene glycol (PEG) plays as antifouling agent. X-ray photoelectron spectroscopy (XPS) and contact angle demonstrated adhesion of P1 and deposition of P2 onto P1 coated substrates. SEM showed reattachment of Hela cells from P2 layered P1 coated substrates (P2-P1) after pretreated at lower pH and higher DTT. This P2- P1 on the substrates can play an essential role as antifouling behavior with well tuned cell attachment and detachment. |
