Abstract: Nano-cholesteryl liguid crystal material is synthesized by condensation polymerization. Changing the chiral components content and chiral temperature and ad usting the intermolecular nano-pitch lead the polymer to different optical and spectrum behaviour. The sample is synthesized, which has even surface. Its colour changes with the incident ray angle and observation situation. The eXperiments show that the material has an potential application in the field of printing, adornment, false proofand so on.
