Special Issue Information

Dear Colleagues,

Polymer nanocomposites represent a cutting-edge class of materials that combine polymers with nanoscale fillers to enhance and tailor their properties for a wide range of smart applications. These advanced composites leverage the unique characteristics of nanoparticles, such as a high surface area and extraordinary mechanical, thermal, and electrical properties, to significantly improve the performance of the base polymer. In smart applications, polymer nanocomposites find uses in areas such as sensors, actuators, drug delivery systems, self-healing materials, and several others. Their ability to respond dynamically to environmental stimuli such as temperature, pH, and electric or magnetic fields makes them ideal candidates for innovative technologies that require adaptive, responsive, and multifunctional materials. As research progresses, the potential for polymer nanocomposites to revolutionize various industries, from healthcare to electronics, continues to grow, driven by their versatility and high-performance capabilities.

This Special Issue, entitled “Polymer Nanocomposites for Smart Applications”, invites the submission of high-quality works that highlight recent advances in the field of polymer nanocomposites for smart applications.

Topics of interest for this Special Issue include, but are not limited to, the following:

  • Sustainable polymer nanocomposites, derived from bio-based or renewable resource materials;
  • Recycled polymer nanocomposites;
  • Carbon materials-based polymer nanocomposites;
  • Design of multifunctional polymer nanocomposites for advanced applications, such as EMI shielding, energy storage, sensors, actuators, self-healing, and biomedical;
  • Lifecycle assessment of polymer nanocomposites.

Abstract
The electrospinning technique can produce multifunctional polymeric devices by forming solid fibers from polymer solutions under a high-voltage electric field. Variations such as concentric needles yield core/shell fibers. This study evaluates the effects of applied voltage (12.5–20 kV) and tip-to-collector distance (12.5–20 cm) [...] Read more.
The electrospinning technique can produce multifunctional polymeric devices by forming solid fibers from polymer solutions under a high-voltage electric field. Variations such as concentric needles yield core/shell fibers. This study evaluates the effects of applied voltage (12.5–20 kV) and tip-to-collector distance (12.5–20 cm) on the morphology and thermochemical behavior of PLGA/PVA fibers made by coaxial electrospinning compared with casting-produced membranes and monolithic fibers. Optimal coaxial fibers (597 ± 90 nm diameter) were produced at 15 cm/12.5 kV, exhibiting a well-defined core/shell structure (PVA core: ~100 nm; PLGA shell: ~50 nm) confirmed by laser scanning confocal (core solution labeled with fluorescein) and TEM. FTIR and TGA demonstrated nearly complete solvent removal in electrospun samples versus ~10% solvent retention in cast films. XRD analysis indicated that cast films (PLGAff) exhibited minimal crystallinity (Xc ≈ 0.1%), while electrospun PLGA (PLGAe) showed cold crystallization and higher crystallinity (Tcc ≈ 90.6 °C; Xc ≈ 2.45%). DSC detected two different Tg (≈43.2 °C and 52.8 °C) in the coaxial fibers, confirming distinct polymer domains with interfacial interactions. These results establish precise processing/structure relationships for defect-free coaxial fibers and provide fundamental design principles for hybrid systems in controlled drug delivery and tissue engineering applications.
