Abstract

Molecular composites are polymer blends, in which rigid rod-like “fiber” polymers are molecularly dispersed in flexible polymer matrix1,2. To obtain excellent mechanical properties of the composites, fiber polymers must be so isotropically dispersed in the blend system that no phase separation can be observed3,4. Once phase separation has taken place, the molecular composite transforms to a macroscopic composite, and this phase separation is a serious problem in most of molecular composites. In polymer systems containing rigid-rod polymers a phase separation is particularly facile to occurr, since between the rigid backbones a strong van der Waals attraction is present to form a separate phase. To overcome this phase separation problem a number of novel methods has been introduced for making molecular composites with satisfactory properties.
