Abstract

Procedimiento de preparación de láminas delgadas de cristal coloidal y producto así obtenido. El objeto de esta invención es un método de preparación de láminas delgadas de cristal coloidal limpio, simple, reproducible, rápido y fiable a partir de suspensiones de partículas esféricas coloidales de tamaño micrométrico dispersas en distintas mezclas de líquidos volátiles. El método desarrollado permite obtener en minutos y sin necesidad de un procesado posterior láminas delgadas de cristal coloidal altamente difractantes y con unas propiedades ópticas uniformes en áreas del orden de varios centímetros cuadrados sobre sustratos de muy diverso tipo. El método desarrollado permite controlar con gran precisión el grosor de las láminas. Es además posible elegir la orientación cristalina de la red coloidal entre dos posibles, constituyendo una de ellas un nuevo material del que no existe precedente.Procedure for preparing thin sheets of colloidal glass and product thus obtained. The object of this invention is a method of preparing thin sheets of clean, simple, reproducible, fast and reliable colloidal crystal from suspensions of colloidal spherical particles of micrometric size dispersed in different mixtures of volatile liquids. The method developed allows to obtain, in minutes and without the need for subsequent processing, thin sheets of colloidal glass highly diffractant and with uniform optical properties in areas of the order of several square centimeters on substrates of very different types. The developed method allows to control with great precision the thickness of the sheets. It is also possible to choose the crystalline orientation of the colloidal network between two possible, one of them constituting a new material of which there is no precedent.
