| Abstract: | In this study,a novel cholesteric liquid crystals(Ch-LCs) solid film with wide-band reflection prop-erty was fabricated by two step polymerization of two polymerizable mixtures with different Ch-LCs monomersunder UV irradiation,respectively.One Ch-LCs polymerizable mixture formed polymer network after polymeri-zation,which defined the initial pitch of the structure.The polymer network was refilled by the other Ch-LCspolymerizable mixture.After UV irradiation,the Ch-LCs film can reflect incident light over t... |
| Keywords: | cholesteric liquid crystals pitch gradient wide-band reflection two step polymerization solid film |
