The most significant reasons for functionalizing textiles are the enhancement of current qualities and the development of new material properties. Polymer nanocomposites provide the opportunity to create a new class of nano-finishing materials for textiles with their own system of structure-property relationships that are only indirectly connected to their components and their micron and macro-scale composite counterparts. Polymeric matrix nanocomposites made up of inorganic nanoparticles and organic polymers are a new class of materials that outperform compared to their microparticle counterparts. Incorporating inorganic nanoparticles into a polymer matrix can have a significant impact on the matrix's properties. The characteristics of polymer nanocomposites are determined by the type of nanoparticles used, their size and shape, their concentration, and their interactions with the polymer matrix. When polymer nanocomposite coatings are applied to textiles, they give materials various functionalities, as they can be used in protective fabrics, medical textiles, and conductive textiles…. Etc.
