Computational Modelling of Light-switchable Surface Topograhies Using Liquid Crystal Polymers

Abstract eng:
Liquid crystal (LC) glassy polymers co-polymerized with azobenzenes respond to ultra-violet (UV) light by undergoing anisotropic dimensional changes. Such a light-induced mechanical response can be used to generate topographical deformations when LC films are fixed to rigid substrates. Various topographical changes, dynamically controlled by light, can be produced by controlling the internal distribution of the average orientation of the liquid crystal molecules. In this presentation, we review our recent simulation results of light responsive topographical transformations of LC polydomain coatings [1].
