Abstract

Orientationally ordered polymer networks are prepared in spherical and cylindrical geometries by isothermal photopolymerization of diacrylate molecules dissolved in a nematic liquid crystal. Optical polarizing microscopy textures reveal that the network memorizes the nematic director field. Diacrylate concentrations of 2% by weight suffice to create a stable network embedded in the anisotropic liquid crystal environment for temperatures as high as 150 degree(s)C. Polymer networks that are formed under various surface conditions, applied electric fields, and geometrical constraints are characterized with optical polarizing microscopy.
