PS-r-PMMA-OH

PS-b-PMMA-OH,Random copolymers for substrate modification, but instead used hydroxyl(OH)end grafted PS-r-PMMA and identified surface neutrality through contact angle measurements.The use of the OH end group on the random copolymer allows the copolymer to end-graft itself to the silicon oxide layer of the substrate,and therefore immobilizes it.
