摘要
The curing temperature is found to greatly affect the operating voltage, contrast ratio, hysteresis, and response time of the reversed-mode liquid crystal (LC) gels. For the gels using E48 LC host, the optimal curing temperature is around 40-50degreesC. An LC gel with contrast ratio exceeds 2000:1 (at similar to2degrees collection angle), operating voltage lower than 7 V-rms, and response time of about 20 ms is demonstrated. Potential applications of such LC gels for optical switches, displays, and switchable polarizers are emphasized. (C) 2003 American Institute of Physics.
