Core shell fiber
WebThe core–shell fiber mat consisting of the core PVA-PEG-SiO 2 and shell PVA-GO demonstrates a narrowed peak at 57.4 °C and a broad peak at 201.7 °C. The melting temperature for the core and core–shell compositions seems to be reduced from 227.4 °C to ca. 202 °C due to the amorphous silica and PEG. WebElectrospun fibers with core-shell structure. Core-shell electrospun fibers have received great interest because of their potential in drug delivery applications. Using a coaxial dual-capillary spinneret, one component of the fiber can easily be encapsulated inside another component leading to what is known as a core-shell structured fiber.
