EFFECT OF SHEAR ON THE PHASE DIAGRAM AND MORPHOLOGY OF PC/LCP BLENDS

摘要

A number of studies have considered the effect of temperature on phase separation of polycarbonate (PC)/liquid crystalline polymer (LCP). In this work, the effects of shear on the morphology and phase separation temperatures of the blends at different compositions are studied. A polarized light microscope was used in conjunction with a shear cell to observe the phase separation temperatures and to monitor the development of the phase-separated structures.
