Biodegradable Membrane with High Porosity and Hollow Structure Obtained via Electrospinning for Oil Spill Clean-up Application

2023

The use of biodegradable polymers for the production of membranes to be used in wastewater treatment has attracted increasing interest considering the possibility of reducing the risk of second pollution. In this work, porous fibrous membranes based on polylactic acid and polyethylene oxide (PEO) blends were prepared. The solutions were electrospun using two approaches: (i) conventional coaxial electrospinning followed by leaching treatment (double-step, DS); (ii) coaxial wet electrospinning with in situ leaching (single-step, SS). By varying PEO type and processing method it was possible to control membranes structure and porosity. DS leaching treatment lead to surface porosity (i.e. shell…
