“Background Electrospinning has been regarded as the most effective and versatile technology to produce nanofibrous nonwovens with controlled fiber morphology, dimensions, and functional components from various polymeric materials. Nanofibrous nonwovens have shown excellent porous properties and vast application potential in areas [1, 2] such as biomedical research [3], filtration [4], superhydrophobic surfaces [5, 6], energy conversion and storage [7, 8], reinforcement, sensors, and many others.
