| 中文摘要 | thin films of pst/pmaa and peo-pst-peo block polymers were deposited on a polystyrene substrate by solution adsorption (with or without solvent treatment), and the film surfaces were characterized by means of xps. direct solvent - casting of peo-pst-peo from benzene solutions resulted in pst-rich surfaces, whereas pmaa richer surfaces were obtained for pst/pmaa films cast from dmf solutions. moreover, solvent treatment after casting had profound effect on the film surface composition. treatment with water markedly increased the surface concentration of polar peo segments. in the case of pst-pmaa block polymers, the pst content on the surface increased in the order of water < ethanol < cyclohexane < petroleum ether, the last-named giving films with almost pure pst surface. it is well worth noticing that the bulk composition had little to do with the surface composition for both pst/pmaa and peo-pst-peo block polymers within the composition range investigated when subsequent solvent treatment was applied. |
