Abstract
The subject matter described herein relates to thermoresponsive switching materials that undergo a thermal transition over a narrow temperature range and to devices, such as actuators, indicators, and sensors, prepared from such compositions.
Claims22
A thermoresponsive switching material (TSM) composition comprising:
- (a) a low molecular weight organic compound (LMWOC) that is a crystalline non-polymeric material having a melting point of about 50-120° C., and
- (b) a strengthening agent having a molecular weight of from about 500 to about 5,000 Da as a minor component, wherein the composition has increased mechanical strength compared to the low molecular weight organic compound-based material and substantially the same melting point and melting point spread as the low molecular weight organic compound.
