| 摘 要： | 采用自洽场理论研究球状胶束和平面衬底间由高分子溶剂诱导的排空效应。这一体系中由二嵌段共聚物形成胶束，而均聚物作为溶剂起到排空效应引发剂作用，当球形胶束接近平面衬底时排空效应将使胶束吸附于衬底表面附近。提出通过改变衬底表面的吸引相互作用调控衬底和本体间的界面结构，从而实现对排空效应的调控。

| Abstract: | In this paper, self-consistent field theory is used to study the depletion interaction between spherical micelles and planar substrate induced by polymer solvents. In this system, diblock copolymers form micelles and homopolymer solvents act as depletion initiators. When the spherical micelle approaches the planar substrate, the depletion interaction will allow the micelle to be adsorbed near the substrate. The structure between the substrate and the bulk is controlled through adjusting the amplitude of the attractive interaction of the substrate, which results in the regulation of the depletion interaction. |
