A Review on the Applications of Titanium Dioxide in Polymer Composites and Nanocomposites

Incorporation of inorganic particles and nanoparticles in polymer matrices is the most popular and interesting aspect of composite and nanocomposite synthesis. Polymer/inorganic nanocomposites have attracted much attention as a strategy to improve the properties of synthetic polymers. Among various inorganic particles and nanoparticles, titanium dioxide is an important additive in polymer composites owing to its unique properties such as photocatalytic effect, photostability, chemically and biologically inertness, high refractive index, high dielectric constant, low cost and biocompatibility. The incorporation of titanium dioxide nanoparticles into the polymer matrices gives unique improvements in the properties of the polymer nanocomposites. These nanocomposites could be used in diverse applications. Polymer/titanium dioxide nanocomposites are applied in various areas such as corrosion protection coatings, solar cells, polymer wastes dispose, lithium ion batteries, sensors and actuators. In this paper a brief review on the properties and applications of titanium dioxide nanoparticles in the polymer composites and nanocomposites have been discussed
