Electrospinning is a versatile process technology, exploited for the production of fibers with varying diameters, ranging from the nano to micro scale. The unique properties of electrospun materials make them a potential candidate for a plethora of commercial applications, ranging from medicine to consumer products, and from industrial to high-tech applications such as drug delivery systems, tissue engineering, aerospace, energy storage, fuel cells, and bioremediation. The use of both organic and inorganic nanometric fillers can enhance the final properties of the electrospun materials or endow them with new features such as electrical conductivity, superhydrophobicity, and hydrophilicity.

Therefore, this special issue aims to collate original research and review articles that deal with the relationships between processing, structure, morphology, and properties in electrospun polymeric nanocomposites. We hope that these articles will either provide new insights into the interaction between polymeric matrix and fillers or investigate new electrospun nanocomposites leading to advanced performance with regard to thermal, mechanical, electrical, or biological properties. Latest research dealing with specific applications or proposing novel characterization protocols is also of great interest.

Potential topics include but are not limited to the following:

• Bulk and surface properties of electrospun nanocomposites
• Effect of filler modifications on electrospun nanocomposites
• Compatibilization effect of nanoparticles in electrospun blends
• Electrospun nanocomposites for biomedical applications
• Electrospun nanocomposites for industrial applications
• Electrospun nanocomposites for environmental applications
• Filler dispersion in electrospun nanocomposites
• Fiber morphology of electrospun nanocomposites
• Mechanical properties of electrospun nanocomposites
• Processing-properties-structure-morphology relationships of electrospun nanocomposites
