MATERIALS AND METHODS FOR IMPROVING PROPERTIES OF SPD EMULSIONS AND FILMS

摘要

The invention provides films for use in a suspended particle device (SPD). In addition, the invention provides an emulsifier which forms a film for use in an SPD, and an emulsifier for use in forming a film adapted for inclusion in an SPD. The invention also provides a method for improving stability of an emulsion used in making a film adapted for use in an SPD. The invention further provides a method of reducing coalescence of drops of a liquid suspension medium in an emulsion used in forming a film adapted for use in an SPD. Also provided is a method for improving performance characteristics of a film adapted for use in an SPD.
