Microwave-Assisted Centrifugal Spinning of Gelatin Microfibers

Abstract

<jats:p>MICROWAVE-ASSISTED CENTRIFUGAL SPINNING OF GELATIN MICROFIBERS. Herein, we disclose a method for preparing polymeric microfibers. According to an embodiment of the method, gelatin fibers were prepared from 50% aqueous gelatin solution by centrifugal spinning. The produced material feels similar to wool to the touch. Average fiber diameter was determined to be 40 m. Thermal stability of the material is similar to that of gelatin fibers prepared by other techniques, e.g. electrospinning. Elastic modulus of the fibrous material was determined to be 230 MPa and its toughness was found to be 160 kJ/m3. The described method is one of the fastest low-cost lab-scale fiber production techniques available (as a practical example, the speed of fiber production was roughly 5 g/s) and could be used to prepare various polymeric fibers in an eco-friendly way for a wide range of applications, including textile industry, tissue engineering and drug delivery.</jats:p>

Potential Loading of Virgin Coconut Oil into Centrifugally‐Spun Nanofibers for Biomedical Applications

“…The matrices for wound dressing applications were dominated by synthetic polymers because they were mostly used for external treatment. However, for drug delivery, antibacterial, and antioxidant applications that involve oral supplementation, natural biopolymers such as starch [146][147][148], chitosan [149][150][151], pullulan [152][153][154][155], and gelatin [156][157][158] are preferred. Polymers with good mechanical properties and flexibility, such as PCL/ PU [50][51][52], gelatin/citric acid [159], and chitosan [160][161][162] were applied for medical implant and tissue engineering applications.…”
