Polymeric nanofibers have appeared as unique one-dimensional nanomaterials. Nanofibers possess exceptionally high specific surface area and essential properties. Various polymeric nanofibers and nanocomposite nanofibers have been developed using thermoplastic and thermosetting matrices and organic and inorganic nanoparticles. This review documents the worth of nanofiber technology regarding the synthesis, morphology, physical properties, and applications of the nanostructures. The nanofiber surface morphology and diameter directly influence the physical characteristics such as electrical conductivity, mechanical properties, and thermal stability. Fiber processing techniques and related parameters also affect their texture and properties. In this regard, electrospinning is frequently used to form polymeric nanofibers and nanocomposite nanofibers. Electrospun nanofibers having large surface area and excellent fiber orientation, alignment, and morphology. The polymer nanocomposites with different nanofillers (carbon nanotube, graphene, carbon nanofibers, and other nanoparticles) have been processed into high performance electrospun nanofibers. Electrospun nanomaterials have been applied in engineered structures, nanofibrous membranes, electronic devices, tissue engineering, drug delivery, antibacterial materials and other biomedical applications. Henceforth, this is a comprehensive review on physical characteristics, morphology, processing aspects, and application areas for polymeric and nanocomposite nanofibers.

A new, low‐cost, and direct green synthesis strategy was developed for the preparation of polymer composites composed of silver nanoparticles (AgNPs) decorated on a shape memory polymer blend using Rubus caesius L. leaves. X‐ray powder diffraction, ultraviolet‐visible spectroscopy (UV–vis), scanning electron microscopy, and energy dispersive X‐ray spectroscopy (EDS) elemental composition were applied to characterize the crystal size, morphology, and elemental composition of Ag‐NPs. UV–vis spectra detected the characteristic absorbance signal of AgNPs at about 430 nm, and the average crystal size of nanoparticles was calculated as about 12.60 nm. When nanocomposite films were characterized by attenuated total reflectance infrared spectroscopy, characteristic polylactic acid, and poly ethylene glycol (PEG) signals were determined. From the thermogravimetric analysis curves, it was determined that the amount of residue of nanocomposites increased as the amount of AgNP increased. It was seen that AgNPs did not affect the Tg temperature of the nanocomposite films, while it was also a proof that the polymer blend was immiscible. It was observed that the shape recovery properties of nanocomposite films were better with increasing AgNPs content. Finally, both green synthesized AgNPs and nanocomposites prepared with shape memory polymers showed very good antibacterial activity against Gram‐positive and Gram‐negative bacteria.Highlights Green synthesis of silver nanoparticles (AgNPs) was carried out with Rubus caesius L. leaves. The synthesized AgNPs were characterized by ultraviolet visible spectroscopy and x‐ray powder diffraction. Composite films were prepared with poly lactic acid/poly ɛ‐caprolactone blend by solvent casting method. The amount of residue of nanocomposites increased with increasing AgNPs percentage. The nanocomposite film containing 10% AgNPs has good activity.
