The synthesis of random brush for nanostructure of block copolymer

Abstract

Polymer brush has been synthesized via conventional free radical polymerization to use a surface active material on the silicon substrate. The synthesized polymer brushes were successfully grafted onto the silicon oxide substrate and the hydrophilic silicon oxide substrate has been changed into the more hydrophobic one. The synthesized poly(styrene-ran-methyl methacrylate) brush grafted silicon substrate could provide poly(styrene-block-methyl methacrylate) with neutral surface.
