Abstract
Official abstract text for this publication.
A method of forming a titania-coated inorganic particle comprising the steps of (a) stirring a mixture of a titania precursor such as a titanium alkoxide and an inorganic particle such as a hollow glass particles in an organic solvent such as an alcohol for more than 1 h to cause adsorption of the titania precursor on the surface of the inorganic particle; and (b) adding water dropwise to the mixture under stirring to convert the titania precursor to titania which then forms a coating on the inorganic particle. A method for forming a paint formulation, a titania-coated inorganic particle, a paint formulation comprising a titania-coated inorganic particle and use of a titania-coated inorganic particle in a paint formulation is also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for forming a paint formulation, comprising: stirring a mixture of a titania precursor and an inorganic particle in an organic solvent for a time period of more than 1 hour to cause adsorption of said titania precursor on the surface of said inorganic particle; adding water to the mixture under stirring to convert said titania precursor to titania which then forms a coating on said inorganic particle, wherein water and the titania precursor have a molar ratio in the range of 2:1 to 8:1; separating the titania-coating inorganic particle from the mixture; and adding said titania-coating inorganic particle to a paint formulation.
