摘要
综述讨论聚合物分子复合材料的定义、判据、热力学、制备方法和先进性，简要论述聚合物分子复合材料的研究进展和发展趋势。
The progress of polymer molecular composites was reviewed with 29 references. The concept of molecular composites is created to increase the reinforcing efficiency maximum. By dispersing rigid molecules in a matrix of flexible coils at molecular level, no inherent defects in the composites and synergistic properties are expected. The advantages of molecular composites depend greatly on the degree of phase mixing which can be achieved between the rigid rods and flexible coils. There are several ways to improve the degree of mixing, (1) decrease the rigidity of rod like molecules to increase Δ S mix ;(2)chemically bind the two components to limit the distance of separation; and (3)slow the kinetics of segregation process. Finally the progress in molecular composites is briefly summarized.
