A porous hollow fiber membrane using polylactide (PLA), a representative bio-derived polymer, was successfully fabricated. The use of high surface area fabrics can effectively absorb liquids, making it possible to impart selective absorbency to fabrics made of hydrophobic PLA. In this study, a porous PLA fabric was developed by applying the porosity of the fiber surface depending on the solvent. To increase the total surface area effectively, hollow fibers were fabricated with coaxial electrospinning to maintain the pores of the surface while having a hollow space. Also, the treated silica was coated on the surface of the fabric to provide the functionality. To confirm the selective absorbency of the coated fabric, changes in oil and water absorption were analyzed.
