Abstract
The present subject matter relates generally to the use of thermally induced self-assembly of surfactants, such as poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) or 4-octylphenol polyethoxylate, to vary the transparency or opacity of a composition containing the same. The compositions of the present subject matter can be used in smart window technologies.
Claims17
A liquid or hydrogel composition comprising,
- a. a thermally induced self-assembly surfactant;
- b. an additive;
- c. a liquid carrier;
- and
- d. optionally, a hydrogel base material,
- wherein the composition becomes opaque at or above an opaque-transparent transition temperature (OTTT).
