Synthesis and Frictional Properties of Poly(2,3-dihydroxypropyl methacrylate) Brush Prepared by Surface-initiated Atom Transfer Radical Polymerization

摘要

Surface-initiated atom transfer radical polymerization (ATRP) of (2,2-dimethyl-l,3-dioxolan-4-yl)methyl methacrylate (1) was carried out from an immobilized initiator on a silicon wafer to result in a high-density polymer brush,which was converted to the hydrophilic polymer brush consisting of 2,3-di-hyroxypropyl methacrylate (2) units,successively.The poly(2) brush showed low dynamic friction coefficient in water.
