Surface Redox Initiated Polymerization to Prepare the Poly(N-isopropylacrylamide) Coating

Article Preview

Abstract:

A hydroxylated silicon substrate was modified with 3-aminopropyltriethoxysilane (APTES) monolayer, followed by the surface initiated graft polymerization of the N-isopropylacrylamide (NIPAm). The microstructure of poly(N-isopropylacrylamide) (PNIPAm) coating was examined by X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM), respectively. And the results showed that about 50 nm thickness of PNIPAm coating grafted successfully.
