The Design and Implementation of a Disk Electrospinning Device

Abstract

The electrospinning procedure is a relatively simple and fast way of producing polymer fibers with diameters in the micrometer range. The one needle setup is commonly used due to its flexible design and effectiveness; however, this procedure has one major shortcoming; it has low productivity. The disk electrospinning design presented here combines the advantages of the corona and needleless electrospinning setups, namely the small solution surface area and high productivity. We used 33 wt% polyvinylpyrrolidone (PVP) solution to produce PVP fibers with the new design. The average fiber diameter of the produced PVP fibers was d = 446±116 nm, which is ~25 % larger compared to fibers produced with the one needle method.

Electrospinning of Potential Medical Devices (Wound Dressings, Tissue Engineering Scaffolds, Face Masks) and Their Regulatory Approach

“…Moreover, the method can be supplemented with different external forces, such as magnetic force (ferromagnetic liquid electrospinning or magnetic-field-assisted electrospinning), high-pressure gas flow (bubble electrospinning), or acoustic radiation force generated by an ultrasound transducer (ultrasound-enhanced electrospinning) [ 54 ]. On the other hand, rotating spinnerets are half immersed in the polymer solution, and the multiple Taylor cones are formed on the surface of the cylinder [ 55 ], disc [ 56 ], wire [ 57 ], or ball [ 58 ], while the rotation ensures a continuous solution supply.…”
