Fabrication of triblock liquid crystal elastomer by holography
摘要
Abstract
The preparation method of triblock Liquid Crystal(LC)elastomer films with thermal in-duced contraction was researched and their polarized characteristics and thermal induced contrasctionrates were analyzed.By using the holographic exposure technology,a liquid crystal elastomer with agrid-like structure was prepared.Based on a polarization microscope and a He-Ne laser,grid-likestructure and polarization were detected,respectively.The relationship between the LC molecular a-lignment and the polarization of LC elastomer was analyzed.In addition,the thermal induced contrac-tion rate for LC elastomer was tested.The experimental results indicate that LC molecules are ar-ranged perpendicular to grid-like structure.The deformation rate of thermal induced contraction forthe liquid crystal elastomer can be achieved 12%in the LC phase transition temperature(65-80℃).关键词
