An electrospun nanofibrous layer may include an exemplary polymer scaffold made of at least one of nylon, polyester, polyvinyl alcohol, chitosan, and acrylic, an amine-terminated dendritic polymer that may be attached to and distributed within the exemplary polymer scaffold. An exemplary amine-terminated dendritic polymer may include at least one of polyamidoamine, polypropylene imine, and polyethylene imine. An electrospun nanofibrous layer may further include an exemplary volatile aromatic compound that may be encapsulated within the amine-terminated dendritic polymer.

The invention provides an enhanced electrospun film made from polyvinylidene fluoride (PVDF) and at least one low-melting-point polymer in a ratio of 99.9:0.1-90:10 by weight, and the low-melting-point polymer having a melting point lower than the polyvinylidene fluoride and a softening point in the range of 110-140 C. The enhanced electrospun film exhibits excellent mechanical properties, higher moisture permeability and hydrostatic pressure resistance. The invention further provides a method for manufacturing the enhanced PVDF electrospun film, and use of the enhanced PVDF electrospun film in preparing a waterproof and moisture permeable product.
