5 Claims

1. A method for fabricating a nanofibrous fabric layer, the method comprising:

preparing a first polymer solution by dissolving a base polymer in a first solvent, the base polymer comprising one of nylon, chitosan, and combinations thereof, the first solvent comprising one of formic acid, dimethyl formamide, acetic acid, dimethyl formamide, and mixtures thereof;

adding a surfactant to the polymer solution;

preparing a second polymer solution by dissolving an amine-terminated dendritic polymer and a volatile aromatic compound in a second solvent, the second solvent comprising one of methanol, ethanol, water, dimethyl formamide, and mixtures thereof, wherein the volatile aromatic compound includes an essential oil;

preparing a spinning solution by dispersing the second polymer solution into the first polymer solution; and

electrospinning the spinning solution to obtain the nanofibrous layer.
