Abstract
AbstractPoly(methyl methacrylate) (PMMA) brushes grafted from silicon wafer surface were prepared using a reversible addition fragmentation chain transfer (RAFT) technique. 4‐Cyano‐4‐((thiobenzoyl)sulfanyl)pentanoic succinimide ester, a novel RAFT agent, was immobilized on the silicon wafer surface. RAFT polymerizations were then conducted from the silicon surface to polymerize from the silicon surface. Kinetic studies revealed that the thickness of the PMMA film increased almost linearly with the polymerization time after 2 h, indicating that the chain growth from the surface was a controlled process with a "living" character. The PMMA brushes were characterized using ellipsometry, X‐ray photoelectron spectra (XPS), atomic force microscopy (AFM) and contact angle measurements.
