摘　　要：采用基于金兹堡-朗道理论(Ginzburg-Landau Theory)的元胞动力学方法(Cell Dynamic System)研究光掩膜诱导的聚合物/纳米粒子共混体系的自组装行为。探讨掩膜、光照强度、聚合物组分比、纳米粒子浓度、聚合物-纳米粒子相互作用等因素对体系形貌形成和演化的影响,构建体系结构与相关参数的二维相图,同时分析结构形成的动力学过程,揭示各参数间的相互作用机理,获得了调控复合体系花样结构形成和转变的简便方法,为新型高性能微纳米材料的制备提供参考。Self-assembly behavior of photomask-induced polymer/nanoparticle mixing systems was studied with cell dynamic system method based on Ginzburg-Landau theory.Effects of reaction rate,number of masks,composition ratio,concentration of nanoparticles and compatibility with polymer on morphology and structure of the system were discussed in detail.A two-dimensional phase diagram of the system structure and related parameters was constructed.Interaction mechanism and rules of components in the blend system and photomask regulation were obtained.A simple method was obtained to control pattern structure formation and transformation of the composite system.It provides references for the preparation of novel high-performance micro/nano materials.
