The Influence of Thermal Property of the Polymer on the Polymer-Stabilized Blue Phase

Abstract A relationship between polymer relaxation property and the stability of a polymer-stabilized liquid crystal blue phase was investigated based on differential scanning calorimetory (DSC) and polarizing optical microscopy under temperature gradient. The polymer-stabilizing effect of the blue phase was enhanced by depressing the thermal molecular mobility of the polymer networks in the BP. Keywords: polymer-stabilized blue phase/glass transition temperature
