ULTRAVIOLET RADIATION-CURABLE LIGHT-MODULATING FILM FOR A LIGHT VALVE, AND METHOD OF MAKING SAME

摘要

Provided herein is a film suitable for use as a light-modulating unit for a light valve, which includes a polymer matrix that has been cross-linked by ultraviolet radiation. Preferably, the polymer matrix is a polymer comprising pendant functional groups that can be cross-linked with ultraviolet radiation in the presence of a suitable photoinitiator. The film may be formed by providing an emulsion of the liquid light valve suspension in a liquid UV cross-linkable polymer or oligomer, preferably a polymer, followed by a cross-linking reaction.
