A polarity sensitive electrooptical effect has been observed in nematic liquid crystal–polymermixtures where a gradient of the polymer network density is created by strongly absorbed ultravioletlight. The effect is accounted for by a model based upon consideration of the space chargedistribution caused by the polymerization process. The effect may be of interest for practicalapplications in optical shutters and electrically controlled windows.

Abstract
A polarity sensitive electrooptical effect has been observed in nematic liquid crystal–polymermixtures where a gradient of the polymer network density is created by strongly absorbed ultravioletlight. The effect is accounted for by a model based upon consideration of the space chargedistribution caused by the polymerization process. The effect may be of interest for practicalapplications in optical shutters and electrically controlled windows.File in questo prodotto:
