Utilizing Alternating Field Electrospinning to promote Fish-Skin Gelatin nanofibrous composite materials desired properties.

Electrospun composite nanofibrous (NF) materials have applications in energy, medicine, filtration, catalysts, and many other areas due to their high surface area to pore ratio, variable porosity, structural microarchitecture, mechanical tunability, and easy surface modification. Conventional Direct Current electrospinning (DCES) is broadly used in industry, but has limitations in spinnability and stability of polymer precursors limiting the structure and property control of the NF material produced. This research explores an uncommon, high-yield ES method called alternating field electrospinning (AFES) of NF fish skin gelatin (FSG) biomaterials from an aqueous precursors to complement conventional DCES fabrication of biomaterials. AFES shows benefits of higher production rate, better fiber quality, and neutral fiber collection. Differing concentrations of FSG precursors were ES to determine their spinnability parameters in AFES. The ES FSG precursors viscosities varied from 160 to 4200 mPa.s, had a fiber production rate of 12.6 g/h with 400-500 mPa.s precursor viscosity, which is ×200 more than reported in conventional DCES. The effect of the precursor viscosity on the fiber diameters and microarchitecture of ES materials was explored using a Scanning Electron Microscopy. Overall, AFES showed to be complimentary to conventional DCES and in some cases had the ability to spin a greater variety of FSG-based polymer precursors.Utilizing Alternating Field Electrospinning to promote Fish-Skin Gelatin nanofibrous composite materials desired properties.
