Farzana Ahmad, Muhammad Jamil, Lee Jin Woo, Young Jae Jeon The Absorption of Block Copolymer: Block Copolymer based Polymer Dispersed Liquid Crystal (PDLC) Film


Abstract:
In this work the properties of PDLC film based on block copolymer film are presented. The FTIR; phase transition temperature properties are studied in order to see the absorption of block copolymer with the LC. Optical microscopic work showed the increase in droplet size with the increase in block copolymer contents. It is found absorption of block copolymer does not increase linearly with the increase in its contents. Moreover a decrease in refractive index is observed with the increase in block copolymer contents. The decrease in refractive index of block copolymer with temperature is interesting for thermo-optical and electro-optical devices simultaneously. Keywords: Polymer Dispersed Liquid Crystal (PDLC); Phase separation; Liquid Crystal (LC): FTIR spectroscopy
