摘要：

Polystyrene-block-poly(2-cinnamoylethyl methacrylate) (PS-b-PCEMA) polymers of different asymmetric ratios, beta, and numbers, m, of CEMA units were synthesized and characterized. In cyclopentane/THF mixtures, the polymers were adsorbed by silica mainly via the PCEMA block in the brush conformation. For samples with beta values greater than 4, their surface adsorption data could be well explained by the theory of Marques et al. for diblock adsorption from micelle solutions in the van der Waals-buoy regime. This represents the first experimental confirmation of such a scaling relation. On silver surfaces, the PCEMA block was the main adsorbing species for samples with small beta and large m, and both the PS and PCEMA blocks adsorbed for samples with large beta and small m values. As polymer brushes are not formed from certain polymers, the data of polymer adsorption by silver did not follow the scaling relation of Marques et al.
