聚合物稳定蓝相液晶中温度控制对晶格结构的影响
Lattice structure based on temperature control in polymer-stabilized blue phase liquid crystals
摘要
Abstract
Blue phase liquid crystals(BPLCs)possess several extraordinary optical properties,such as fast response time(sub-milliseconds),Bragg reflection in visible range,optical isotropic property.Meanwhile,polymer-stabilized blue phases LC(PSBPLCs)expanded the temperature range of BPLCs,which makes PSBPLCs have a good application in electro-optical devices.However,photoisomerization perturbs the arrangement of liquid crystal molecules,which induces defects in lattice structures.Herein,we introduce temperature control in photo polymerization.Pure liquid crystal samples and unpolymerized samples of BPLC are tested to find out the relationship between temperature and lattice constants.Based on temperature properties,lattice structures are observed at three different temperature region.Experimental results indicate that the lattice constants of blue phase Ⅰ(BPⅠ)change discretely(about 40 nm)after introducing liquid crystal polymer.Therefore,polymerizing in addition to mid-temperature region could avoid distortion of lattice structures and broadening of spectrum.关键词
