Current wound dressings have disadvantages such as less flexibility, poor mechanical strength, lack of porosity, and a tendency for dressings to adhere onto the wound surface. To overcome these hassles, we have developed flexible and microporous composite wound dressings. In this study, two types composite wound dressing were prepared by electrospinng. The 1# wound dressing consists of TPU fiber (outmost layer), PULL/PVA fiber (middle layer) and chitosan/PEO/mica (innermost layer) while the 2# wound dressing consists of TPU fiber (outmost layer), poly (acrylic acid-co-acrylamide)/poly(vinyl alcohol) fiber (middle layer) and chitosan/PEO/mica (innermost layer). The prepared nanocomposite wound dressings were characterized using Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), and scanning electron microscopy (SEM). |
