Preparation of poly (lactic-co-glycolic acid) microfiber membrane

Poly (lactic-co-glycolic acid) (PLGA) is a kind of medical polymer material with good biodegradability and histocompatibility, which widely used in postoperative anti-adhesion materials. In this paper, PLGA microfiber membrane was successfully prepared poly(lactic-co-glycolic as the main by electrospinning technology. The surface morphology, wettability, dimensional stability mechanical properties films were characterized scanning electron microscopy (SEM) tensile testing machine. results show that average diameter fiber 2.218~2.313 μm, elongation at break film up to 193%, wettability are maintained 37°C. degradation cycle 2~3 months.
