**2. Electrospinning parameters and fiber properties**

Electrospinning can be divided into two methods based on material properties: melt electro‐ spinning and solution electrospinning. The former is less investigated because of its thick resultant fiber and high applied voltage [18], while the latter is widely researched and applied in several areas such as non-woven fabrics. However, melt electrospinning is attracting more and more attention since it can process Polypropylene(PP), polyethylene(PE), and otherther‐ moplastic polymers without using any toxic solvents. Processing parameters always play important roles in judging spinnability and controlling fiber properties in both electrospinning processes.
