Summary
Ethyl-cyanoethyl cellulose [(E-CE)C]/acrylic acid (AA) formed a cholesteric liquid crystalline solution with vivid colors when the concentration is 42–52 wt%. (E-CE)C/polyacrylic acid (PAA) composites with cholesteric structure were prepared by polymerization of the AA in the (E-CE)C/AA liquid crystalline solutions. The layers of ordered polymer chains in the cholesteric phase were inclined during polymerization and the degree of the inclination depended on the polymerization temperature and the concentration of the solution before polymerization.
Key words: Cholesteric structure, polymerization, and selective reflection.
