Abstract

The relationship between dielectric and electro-optical properties of polymer-stabilized blue phases (PSBPs) with different polymer concentration was investigated at low temperature. Dynamics of LC molecular rotation and local reorientation of director in PSBPs are affected differently by polymer network. Through reflection spectra, we found that the ordered structure of PSBPs suddenly decreased at low temperature, and PSBPs with lower polymer ratio and longer chiral pitch maintained the ordered structure until lower temperature.
