제목 Color tuning methods of photonic gel films
초록 Characteristics of the devices using photonic gel film were studied. Poly(styrene-b-2-vinyl pyridine) (PS-b-P2VP) lamellar film which has hydrophobic block-hydrophilic block copolymer of 52 kg/mol -b- 57 kg/mol were prepared for photonic gel films. The lamellar structure was 1 dimension photonic crystal. That photonic gel films were swollen by various solutions. Typical swelling solutions are deionized water and low molecular weight alcohols. The reflect color was changed by swelling water which contained a few of metal ions. Likewise, hydrogen ion concentration changing was shown similar effects. The photonic gel film which has Ca2+ ions was max-reflectance wavelength shifted 653nm to 451nm and which has Cu2+ ions was shifted 653nm to 516nm. The more decreased hydrogen ions concentration of swelling solution, the more shifted to short wavelength(789nm to 593nm). We can control color of photonic gel film devices by changing the condition of swelling solution.
