The Use of Cholesterically-Ordered Polymer Networks in Practical Applications

Cholesteric polymer films produced by the photo-initiated polymerization of liquid-crystalline diacrylates containing a small amount of chiral dopant are demonstrated to be applicable as foils to compensate for the wavelength dependence of the transmission of supertwisted nematic liquid-crystal displays and to possess the appropriate thermal behaviour for use as a coating or encapsulation material for low-stress packaging of electronic devices.
