Abstract:
(EN) The invention relates to a thermochromic material comprising at least one biopolymer, at least one natural dye and at least one reaction medium, selected from the group of fatty acids and derivatives thereof, gallic acid and derivatives thereof and mixtures thereof. The thermochromic material according to the invention is completely based on non-toxic, natural products. Processing into materials or molded articles can occur, according to the invention, by means of conventional extrusion technology in the form of flat film, blown film or sheets or multi-wall sheets. The thermochromic material can be used in particular in the food industry and medical technology.
(FR) L'invention concerne une matière thermochrome contenant au moins un biopolymère, au moins un colorant naturel ainsi qu'au moins un agent de réaction sélectionné dans le groupe constitué par les acides gras et leurs dérivés, l'acide gallique et ses dérivés, ainsi que des mélanges de ces derniers. La matière thermochrome selon l'invention est ainsi basée sur des produits naturels ne présentant absolument aucune toxicité. La transformation en matériau ou en corps moulé sous forme de films plats, de films soufflés, de plaques ou de plaques nervurées peut être effectuée au moyen de techniques d'extrusion classiques. La matière thermochrome est en particulier destinée à être utilisée dans l'industrie alimentaire et les techniques médicales.
(DE) Die Erfindung betrifft ein thermochromes Material enthaltend mindestens ein Biopolymer, mindestens einen Naturfarbstoff sowie mindestens ein Reaktionsmedium, ausgewählt aus der Gruppe der Fettsäuren und deren Derivate, Gallussäure und deren Derivate sowie Mischungen hiervon. Das erfindungsgemäße thermochrome Material basiert dabei vollständig auf toxitätsfreien Naturprodukten. Die Verarbeitung zu Werkstoffen oder Formkörpern kann mittels konventioneller Extrusionstechnik in Form von Flachfolien, Blasfolien oder Platten bzw. Stegplatten erfolgen. Verwendung findet das thermochrome Material insbesondere in der Lebensmittelindustrie und der Medizintechnik.
