Abstract
|
Dense and homogeneous grafted polymer layers were anchored from the melt onto a siliconwafer modified with a macromolecular anchoring layer rich in epoxy functional groups. A monolayer ofpoly(glycidyl methacrylate) (PGMA), attached to silicon wafers, served as the macromolecular anchoringlayer. Carboxylic acid- and anhydride-terminated polystyrenes (PS) of different molecular weights wereused for the grafting. The grafted layers did not dewet at elevated temperatures and did not desorb in agood solvent under ultrasonic treatment. Comparison of the results for the grafting to the PGMA primarylayer with literature data obtained for the grafting to the epoxysilane monolayer suggested that therewere many similarities between these grafting processes. The same major trends were observed. However,the grafting to the PGMA layer was much more effective. We attribute the high efficiency of the PGMAanchoring layer in the grafting reactions to the high mobility of the epoxy reactive groups and formationof an interpenetrating zone at the PS/PGMA interface.
