Chitosan as matrix for bio-polymer dispersed liquid crystal systems

► Polymer dispersed liquid crystal composites based on chitosan polymer matrix were obtained. ► The 4-cyano-4′-pentylbiphenyl liquid crystal droplets have a radial configuration. ► Submicronic droplets were obtained for low content of liquid crystal. ► The micronic dispersion of liquid crystal into chitosan matrix results in a better luminescence.
