TEMPERATURE-SENSING COMPOSITION

Temperature-sensing compositions can include an inorganic material, such as a semiconductor nanocrystal. The nanocrystal can be a dependable and accurate indicator of temperature. The intensity of emission of the nanocrystal varies with temperature and can be highly sensitive to surface temperature....

Beschreibung
Zusammenfassung:	Temperature-sensing compositions can include an inorganic material, such as a semiconductor nanocrystal. The nanocrystal can be a dependable and accurate indicator of temperature. The intensity of emission of the nanocrystal varies with temperature and can be highly sensitive to surface temperature. The nanocrystals can be processed with a binder to form a matrix, which can be varied by altering the chemical nature of the surface of the nanocrystal. A nanocrystal with a compatibilizing outer layer can be incorporated into a coating formulation and retain its temperature sensitive emissive properties. L'invention concerne des compositions de détection de température contenant un matériau inorganique, tel qu'un nanocristal semiconducteur. Ce nanocristal peut être un indicateur fiable et précis de température. L'intensité d'émission du nanocristal varie en fonction de la température et peut être très sensible à la température de surface. Les nanocristaux peuvent être traités à l'aide d'un liant afin de former une matrice, laquelle peut varier par altération de la nature chimique de la surface du nanocristal. Un nanocristal pourvu d'une couche externe compatibilisante peut être introduit dans une préparation de revêtement et conserver ses propriétés émissives thermosensibles.
