The electrospining technique is a well-known process for making continuous sub-micron to nano-size fibers in the nonwoven mat form. Such thin fibers provide unexpected high surface area to volume ratios and are of interest for many applications ranging from textile to composite reinforcement, biomaterials, membranes, and sensors.

Membrane applications: Thanks to a high interconnected porosity (>90%) and tunable pore size, electrospun nanofibrous mats show an extraordinary permeability and selectivity thereby a very high potential for filtration applications as a membrane.

In our group, we aim to develop functional electrospun nanofibrous membranes for a diverse range of applications including water treatment and gas filtration.

Sensoric applications: High surface area to volume ratio is an advantage that makes electrospun nanofibers a unique structural element for sensoric applications. Such characteristic enhances the exposure of the incorporated sensitive substances to the stimulus benefited thereby a higher sensoric efficiency.

In our group, we are working on developing gas and light sensors based on electrospun nanofibers. Additionally, the nanofibrous membranes with switchable properties are of our other interests.
