Titanium dioxide nanoparticles synthesis methods and their application in coatings: A review

Abstract

Today, the use of mineral pigments is very common in improving polymeric coatings properties and in creating nano composite coatings with optimal properties. Titanium dioxide is the most important white pigment used in coating industry, which is used for optimally disperse visible light. Titanium dioxide is present in two main crystalline structures of Anatase and rutile. Titanium dioxide rutile pigments are preferred over the better light scatter and durability than Anatase. Titanium dioxide is a good pigment because of its chemical resistance, photocatalytic properties, self-cleaning properties and also non-toxicity. In this article, we will introduce the different types of titanium dioxide nanoparticles, their photocatalytic performance, environmental issues, various methods of synthesis, and the properties of corrosion resistance of nano composite coatings.
