ABSTRACT
Incorporation of nanofillers in polymeric systems to fabricate useful polymer nanocomposites has been a popular approach in the last three decades for imparting functional attributes to polymers. Among different nanomaterials, polyhedral oligomeric silsesquioxane (POSS), with its versatile chemistry and unique properties, has made its mark among the topmost nanomaterials for research following its commercialization. Electrospinning, a simple and versatile technique with the ability to produce nanoscaled-diameter ultrathin fibers or nanofibers, has played a key role in shaping the nanocomposite fiber production. Fibers and nanofibers are an important class of nanocomposite forms, and fiber scientists worldwide have developed various types of POSS nanocomposite filaments and nanofibers and analyzed their properties. Fibers with preferential alignment of polymer macromolecules toward the fiber axis are an important class of different nanocomposite forms, along with films and molded bars. The nanocomposite fibers presented a continuous morphology with uniform dispersion of nanofillers.
