Abstract

Eleven polystyrene-block-poly(2-cinnamoylethyl methacrylate) (PS-b-PCEMA) samples with molar masses varying over 30-fold were prepared and characterized. Each of the samples had approximately equal styrene and CEMA lengths. Ten of the samples formed stable micelles in THF/cyclopentane (CP) with 82% of CP by volume. The micelles deposited from the THF/CP mixture to form brushes on silica surfaces. The adsorption data of the seven samples having relatively high molar masses followed the theoretical scaling relation derived by Marques et al. for diblock adsorption from micellar solution in the buoy-dominated regime.
