| 中文摘要 | we have investigated systematically the morphology of thin films spin-coated from solutions of a semicrystalline diblock copolymer, poly(l-lactic acid)-block-polystyrene (plla-b-ps), in solvents with varying selectivity. in neutral solvents (chloroform and tetrahydrofuran (thf)), a spinodal-like pattern was obtained and the pattern boundary was sharpened by diluting the solution. meanwhile, loose spherical associates, together with larger aggregates composed of these associates by unimer bridges, formed partly due to crystallization of the plla blocks in relatively concentrated solutions. in slightly ps-selective solvent (e.g., benzene), both loose and compact spherical micelles were obtained, depending on the polymer concentration, coexisting with unimers. when enhancing the selectivity with mixed solvents, for example, mixing the neutral solvent and the slightly selective solvent with a highly ps-selective solvent, cs2, loose assemblies (nanorods in cs2/thf mixtures and polydisperse aggregates in cs2/benzene mixtures) and well-developed lamellar micelles were obtained. |
