主　　题：dip-coating block copolymer thin films supramolecular polymers 

摘      要：This contribution shows the strong influence of using chloroform instead of THF on the characteristics of thin films of supramolecular block copolymers of poly(styrene-b-4-vinyl pyridine) dip-coated in the so-called capillarity regime from solutions containing 1-naphthol or 1-naphthoic *** small molecule content in the dip-coated films was investigated by infrared spectroscopy and the film morphology by atomic force *** was found that the small molecule content in the films is constant with dip-coating rate in the range investigated,but it is higher for 1-naphthoic acid than for *** main morphology observed was in the form of islands and holes,which is typical of flat-on *** findings are related to hydrogen-bonding between the small molecule and pyridine being conserved in chloroform and to the good solubility of both blocks in this solvent,with differences between the two small molecules related to their differing H-bond *** findings contrast strongly with what was observed previously using THF as a solvent,for which the SM content increases with dip-coating rate and the morphologies are mainly spherical and cylindrical in the same parameter range.
