Abstract

Environment-friendly membranes were fabricated from poly (lactic acid) (PLA) via the electrospinning technique. PLA is selected due to its biodegradability and thermoplastic. Firstly, the electrospinning parameters that affect the membrane structure and fibers morphology were identified. These include the polymer solution concentration, flow rate and salt additive. It was found that low concentration lead to smaller fiber size but with beads, and lower flow rates leading to thinner and uniform fibers, while salt additives limited the formation of beads. It was found that hot pressing only is preferred from the view of small pore size, large porosity and high contact angle.
