Normally Scattering(NS)/Normally Transparent (NT) 고분자 분산형 액정 모드에서 UV 조건에 따른 전기 광학특성 연구
Study on the Electro-Optic Characteristics Depending on UV Condition in the Normally Scattering(NS)/Normally Transparent(NT) Polymer Dispersed Liquid Crystal Mode
초록
Polymer dispersed liquid crystal mode can be classified into two cases, normally scattering mode (NS) and normally transparent (NT) mode according to an initial state. Electro-optic characteristic NS/NT PDLC mode can be improved by controlling the factors to influence the phase separation. In case of NS PDLC mode, we inspected change of a phase separation as a function of curing temperature for the mixture of E7 and NOA65 with different ratios. When the LC concentration is less than polymer such as LC : NOA65 = 40 : 60wt%, the PDLC cell is influenced strongly by the curing temperature. However, when LC concentration is much less than polymer such as LC : NOA65 : 80 : 20wt%, it is influenced slightly by the curing temperature. In case of NT PDLC mode, we observed change of a phase separation as a function of the ratio of the mixture and UV conditions such as curing temperature, UV intensity The cell made with strong UV intensity and curing temperature of
