Co-solvent를 이용한 poly(lactic acid) 나노섬유 제조

초록

Poly(lactic acid) belong to the family of aliphatic polyesters commonly made from α-hydroxy acids. PLA is a thermoplastic, high strength, high modulus polymer used in sutures and dental, orthopedic, and drug delivery systems. Solvents may lead to changes in mechanical property and morphology. Electrospinning is a unique technique for the of ultrafine fibers with diameters in submicrometers. Because electrospun mat has high specific surface area and high prosity, we can apply to membranes, scaffolds and sensors. In this study, we investigated the effect of the co-solvents on the electrospinnability of Poly(lactic acid).
