CA 2593692

Devices are described that include a component comprised of a material having a structure of R1 - C(O) - NX - R2, wherein each of R1 and R2 is independently a saturated alkyl having between 7-22 carbon atoms or an aryl, X is H or C(O)- Y, Y together with R1 forms a ring. The material is characterized by a single, sharp melting point, thus making it suitable for use, for example, in thermo~mechanical actuating devices or in temperature-indicating devices. Also described are compositions comprising two or more materials each having a structure of Rn 1 - C(O) - NH - R2 wherein, nis an identifying integer corresponding to a material in the composition; wherein for each material n in the composition, Rn 1 and Rn 2 are a saturated alkyl having between 7-22 carbon atoms, wherein for each material n Rn 1 and Rn 2 differ by one carbon atom, and wherein the number of carbon atoms in Rn 2 of each material ndiffers by four or less.

L'invention concerne des dispositifs contenant un composant constitué d'un matériau ayant la structure R1 - C(O) - NX - R2, R1 et R2 étant indépendamment un alkyl saturé portant 7 à 22 atomes de carbone ou un aryl, et X étant H ou C(O)-Y, Y et R1 formant un cycle. Ledit matériau est caractérisé par un point de fusion unique, précis, ce qui le destine à une utilisation dans des dispositifs d'actionnement thermomécaniques, ou dans des dispositifs indicateurs de température. L'invention concerne également des compositions contenant au moins deux matériaux présentant chacune la structure Rn 1 - C(O) - NH - R2, n étant un entier correspondant à un matériau dans la composition. Et pour chaque matériau n de la composition, Rn 1 et Rn 2 sont indépendamment un alkyl saturé portant 7 à 22 atomes de carbone et diffèrent de l'ordre d'un atome de carbone, et le nombre d'atomes de carbone dans Rn 2 de chaque matériau n diffère de l'ordre de 4 atomes ou moins.
