Title (EN) MICROENCAPSULATED THERMOCHROMIC MATERIALS AND USES THEREOF
(FR) MATÉRIAUX THERMOCHROMIQUES MICROENCAPSULÉS ET LEURS UTILISATIONS
Abstract:
(EN) A variety of particles forming microencapsulated thermochromic materials are provided. The particles can include a thermochromic core and a metal oxide shell encapsulating the thermochromic core. The thermochromic core can include one or both of an organic thermochromic material and an inorganic salt thermochromic material. In some aspects, the particles include a dye selected from a crystal violet lactone dye, a fluoran dye, and a combination thereof. In still further aspects, the particles include a color developer selected from a hydroxybenzoate, a 4, 4'-dihydroxydiphenyl propane, a hydroxycoumarin derivative, a lauryl gallate, and a combination thereof. In some aspects, the metal oxide shell is a TiO2 shell. The particles can be used in cements and paints and for a variety of building materials. Methods of making the particles and building materials and methods of use, for example, for removing a volatile organic carbon from a building material, are also provided.
(FR) L'invention concerne des matériaux thermochromiques microencapsulés formés à partir d’une variété de particules. Les particules peuvent comprendre un noyau thermochromique et une enveloppe d'oxyde métallique encapsulant le noyau thermochromique. Le noyau thermochromique peut comprendre l’un ou les deux éléments parmi un matériau thermochromique organique et un matériau thermochromique à base de sel inorganique. Dans certains aspects, les particules comprennent un colorant pouvant être un colorant de type cristal violet lactone, un colorant à base de fluorane, ou une combinaison de ceux-ci. Dans encore d'autres aspects, les particules comprennent un révélateur de couleur pouvant être du hydroxybenzoate, du 4, 4'-dihydroxydiphényle propane, un dérivé d'hydroxycoumarine, un gallate de lauryle, ou une combinaison de ceux-ci. Dans certains aspects, l’enveloppe d'oxyde métallique est une enveloppe TiO2. Les particules peuvent être utilisées dans des ciments et des peintures et pour une variété de matériaux de construction. L'invention concerne également des procédés de fabrication des particules et des matériaux de construction et des procédés d'utilisation, par exemple, pour l’élimination du carbone organique volatil d'un matériau de construction.
