Development of materials with an antimicrobial activity is fundamental for different sectors, including medicine and health care, water and air treatment, and food packaging. Electrospinning is a versatile and economic technique that allows the incorporation of different natural, industrial, and clinical agents into a wide variety of polymers and blends in the form of micro/nanofibers.

A continuous near-field electrospinning NFES process has been developed to deposit solid nanofibers with orderly patterns over large areas. Before the onset of electrospinning, a bias voltage is applied to a semispherical shaped polymer droplet outside of a syringe needle, and a probe tip mechanically draws a single fiber from the droplet to initiate continuous NFES. Contrary to the conventiona...

Ordinarily, the electrospinning process generates one-dimensional fibers which assemble into nonwoven membrane structures due to instabilities in the fluid jet. In this paper, an electrospinning procedure is developed that utilizes patterned collectors to produce aligned membranes with designed topological structures. The template-assisted electrospinning approach is demonstrated using polycapr...

In many emerging high value electrospinning applications, the diameter distribution of electrospun nanofibers has important implications for the product’s performance and process economics. However, the current state-of-the-art electrospinning process results in varying diameter distributions, both during a run and from run-to-run. To address this problem, our research is focused on developing ...

Electrospinning or electrostatic fiber spinning is an emerging technology that requires electric fields for the formation of non-woven materials that can be used in clothing, highperformance filters, separation membranes, scaffolds in tissue engineering, reinforcement in composite materials, templates for the preparation of functional nanotubes, and many others applications [1]. Polycaprolacton...

The electrospinning of gelatin with tunable fiber morphology from round to flat/ribbon was shown, and the detailed studies were conducted to correlate the fiber morphology with electrospinning process parameters and gelatin concentration in electrospinning solution. Particularly, variations in the applied voltage and the concentration of gelatin led to the transition of fiber shape from round t...
