中文摘要：

使用自洽场理论研究了二嵌段共聚物体系在一维平行板间和三维球腔内的自组装行为．研究表明，在三维球腔内受限状态下，体系可以形成多种介观结构，这些结构是在本体和一维或二维受限状态下不能观察到的．嵌段共聚物受限在球腔内自组装的相行为非常复杂，结构间的转变比一维平行板间受限状态下自组装结构的转变要复杂得多．

英文摘要：

Self-assembly of diblock copolymers under one-dimensional planar and three-dimensional spherical confinements was studied using self-consistent field theory （SCFT）. Under three-dimensional spherical confinement, the diblock copolymer formed various structures which could not form in the bulk and one-dimensional or two-dimensional confinements. The phase behavior of the diblock copolymer under spherical confinement was found to be more complicated than that under planar confinement.
