Summary
The relationship between the electrooptical properties, morphology and molecular weight of polymethylmethacrylate (PMMA) in PMMA/liquid crystal composite films is clarified. The LC droplet size has decreased with increasing molecular weight of PMMA. The threshold voltage has increased with increasing molecular weight of PMMA in good agreement with a equation of Doaneet al, qualitatively. Electrooptical response characteristics have included fast and slow mode. Thermal motion of PMMA at the interface between PMMA and LC seems to affect response time.
