Abstract

AbstractThe director configuration, state of liquid crystal (LC) phase aggregation, and the electooptic properties of thin polymer films of poly(methyl methacrylate) (PMMA) containing nematic liquid crystal have been studied. Measurements included scanning electron micrograph (SEM), polarized optical micrographs (POM), and transmittance response of the film with the applied electric AC voltage and frequency. Two types of PMMA with significantly different molecular weight (Mw) were used, and the effects of polymer molecular weight on morphology and electro‐optic properties of the composite films were examined. © 1995 John Wiley & Sons, Inc.
