摘要：

Scanning force microscopy images of thiol-end-functionalized polystyrene monolayers, end-grafted to gold substrates from good solvent, showed two structural regimes in bad-solvent conditions. At low and moderate grafting densities the experimental results agree with the scaling arguments and can be situated correctly to the corresponding diagram of states for single end-grafted chains and pinned micelles, respectively. A third structural regime, of semicontinuous dimples, has been observed when adsorption was performed from poor-solvent conditions.
