Title (EN) HIGHLY SCATTERING POROUS MATERIAL BASED ON FIBRILLAR, ELONGATED, OR DISK-LIKE PARTICLES
(FR) MATÉRIAU POREUX À FORTE DIFFUSION À BASE DE PARTICULES FIBRILLAIRES, ALLONGÉES OU DISCOÏDES
Abstract:
(EN) The present invention concerns a material, based on fibrillar, elongated, or disk-like colloidal particles, that has a high scattering efficiency, a method that is suitable for preparing such a material, and the use of such a material. The material can be used as, or as a part of, a pigment, paint or protective coating in various industries, but due to its high scattering, and due to the fact that the material appears white even as a thin membrane, it is an interesting option also in the paper and pulp, cosmetic and medical industries.
(FR) La présente invention concerne un matériau, à base de particules colloïdales fibrillaires, allongées ou discoïdes, qui a une efficacité de diffusion élevée, un procédé qui est approprié pour la préparation d'un tel matériau et l'utilisation d'un tel matériau. Le matériau peut être utilisé en tant que pigment, peinture ou revêtement protecteur, ou en tant que partie de ceux-ci, dans diverses industries, mais en raison de sa forte diffusion et en raison du fait que le matériau a un aspect blanc même sous forme d'une fine membrane, il représente une option intéressante également dans les industries papetières, cosmétiques et médicales.
