Abstract

The influence of the helical twisting power (HTP) on the morphology and electro-optical properties of normal-mode polymer-stabilized cholesteric texture (NB-PSCT) was investigated. In this study

PSCT was prepared by the means of polymerization induced phase separation (PIPS). The three PSCTs were in same pitch length by controlling the weight ratio of chiral dopants with different HTP

respectively. The investigated results suggested that as the value of HTP increases

the polymer networks become tighter

which leads to the reduction of the threshold voltage and saturation voltage

and the increase of the field-off response time and hysteresis width. It is attributed mainly to the stronger elastic force between the LC molecules and polymer networks.
