Surface hydroxylation of polyethylene by plasma polymerization of allyl alcohol and subsequent silylation

Silylation of silica and glass is commonly used to prepare model surfaces for studies of the interactions of biological fluids and tissues with materials. In this work, the silylation of modified polyethylene surfaces has been investigated in the same context. Microwave frequency plasma polymerization of allyl alcohol was used to hydroxylate polyethylene (PE) surfaces followed by treatment with NaBH4 and then with chlorosulphonylphenylethyl …
