The small length scales present in nanoscale systems directly influence the energy band structure and can lead indirectly to changes in the associated atomic structure termed as quantum confinement. Conventional polymer composites usually reinforced by micrometer scale fillers into polymer matrices involve compromises in properties. Nanoscale filled polymer composites or polymer nanocomposites gave a new way to overcome the limitations of traditional counterparts. Polymer nanocomposites are synthesised through different techniques depend on their nature. Stereoregular polypropylene is produced due to its industrial use. The properties of polypropylene Ti. O2 nanocomposite material improved compared to polypropylene in terms of antibacterial, mechanical, UV protection, thermal and hydrophilicity properties. Key words polypropylene, nanocomposite, Ti.
