Abstract:
The invention concerns a substrate (1) provided over at least part of its surface with a coating having photocatalytic and/or hydrophilic properties. The substrate is associated with a device (2) for dispensing water on said coated surface. The invention also concerns a method using said combination.
Abstract:
The invention concerns a method from cathode spray deposition of a coating with photocatalytic properties comprising titanium oxide at least partly crystallised in anastatic form on a transparent or semi-transparent support substrate, such as glass, vitroceramic, plastic. The substrate is sprayed under a pressure of at least 2 Pa. The invention also concerns the resulting coated substrate, wherein said substrate constitutes the top layer of a series of thin antiglare layers.
Abstract:
The invention concerns a method for obtaining a substrate (1) provided with a coating (3) with photocatalytic properties, crystallised particles of an oxide of metal A with photocatalytic properties being incorporated in said coating by means of a mineral binder (5) comprising at least an oxide of metal B also having photocatalytic properties in crystallised form and optionally at least an oxide of metal M devoid of photocatalytic properties and/or at least a silicon compound such as silicon oxide SiO2. It consists in depositing the coating (3) from liquid phase dispersions containing: said crystallised particles of metal A oxide; at least a precursor compound of the binder (5) of metal B oxide and optionally a precursor compound of metal M oxide and of the Si compound, in a relative proportion A(B + M + Si) by weight ranging between 60/40 and 40/60. The invention also concerns the resulting coated substrate and its various applications.
Abstract:
The invention concerns a transparent substrate, in particular made of glass, provided on at least one of its surfaces a layer based on a silicon derivative at least partially oxidised selected among silicon dioxide or oxides hypostoichiometric in silicon oxygen, silicon oxycarbide or oxynitride, and having hydrophile properties.
Abstract:
The invention relates to a substrate having on at least a portion of one of its faces a photocatalytic coating based on titanium dioxide at least partially crystallized and incorporated into the coating partially in the form of substantially crystallized in anatase form. The invention also relates to a method for preparing such substrates and to organic dispersions of titanium dioxide particles used in said process for preparing this substrate.
