Electrospinning is one of the most basic techniques for the production of nanoscale fibers.Electrospun nanofibers have excellent properties including small diameter

high surface area to volume ratio and high porosity

thus making them excellent candidates for filtration

catalysis

sensors as well as in biomedical applications.Moreover

multifunctional nanocomposites can be obtained with different functions and elements being hierarchically incorporated into electrospun nanofibers

which will largely broaden their applications in water treatment

healthcare

defense and other technologies.Herein

some recent progress in preparation

structures and properties of hierarchically organized polymer nanocomposites based on electrospun nanofibers are briefly summarized and discussed along with their prospect in practical applications.
