Microchannel Confined Surface Initiated Polymerization



Chang Xu, Tao Wu, Charles M. Drain, J Batteas, Kathryn L. Beers


Surface initiated atom transfer radical polymerization was successfully carried out inside a microchannel, which was formed by placing a patterned poly(dimethylsiloxane) (PDMS) stamp on top of an initiator modified flat silicon substrate. Both surface areas extended with polymer brushes inside the channel and those covered by PDMS retained their initiating capacity, which enables the construction of complex pattern of polymer brushes on surface. By establishing a solution composition gradient inside the microchannel, it is possible for us to study how solution composition will influence the surface initiated polymerization combinatorially, within one experiment
