Production of Nanofibrous Wound Dressings Via Solution Blowing

In this study, thermoplastic polyurethane (TPU) nanofibers were produced via a novel technique: solution blowing. Smoke tree oil was obtained with soxhlet extraction and according to GC-MS analysis; it was shown that obtained extract includes constituents with high antimicrobial activity. Therefore, TPU nanofibers coated with smoke tree oil at different amounts using drop casting in order to obtain antibacterial nanofibers. All coated nanofibers showed antibacterial activity against to S.Aureus and E.Coli. On the other hand, SEM images show that increase of amount of smoke tree oil effect to fiber morphology negatively. Thus, air permeability of nanofibers mats decreased significantly
