Inventor: Yanlei Yu, Li Lin, Weiru Wang, Jixiang Xu

Applicant: Fudan University

Patent No.: ZL 200710038100.3

Abstract：

The invention discloses a new photo-induced deforming liquid crystal macromolecular material in liquid crystal macromolecular material technical domain, which is characterized by the following: choosing ethoxyl group as main chain and azo-benzene derivant as lateral chain with part crosslinking; choosing azo-benzene derivant of monocyclic oxygen group and bicycle oxygen group as monomer; mixing finite quantity light trigger and trigger of positive ion; putting into reactor; choosing proper reacting temperature; copolymerizing the light trigger positive ion under the function of wavelength light; getting the product. This material is a controlled photo-inducer flexural deformation material, which can be used to study driver and artificial muscle.
