Monolayers and Langmuir-Blodgett films of liquid crystalline polymers

Two series of the side - chain liquid crystalline polysiloxanes (LCPs), chi ral LCPs and photochromic LCPs, were chosen to study their monolayer behavi ors at the air/water interface when they were in pure states or mixed with arachidic acid (AA). Their LB film transfer properties and film structures were characterized as well. The aggregation phenomena in monolayers and LB multilayers were systematically characterized by different spectral and sur face morphology observation methods. The functionality of these LCPs in LB films was preliminarily tested.
