Preparation of PCL/chitosan/sesame oil composite nanofiber by coaxial electrospinning

In recent years, an advanced coaxial electrospinning has developed for using two different polymeric solutions for the fabrication of core-sheath structures [1]. In coaxialelectrospinning, two solutions are simultaneously electrospun through different feeding capillary channels into one nozzle togenerate the composite nanofibers with core-sheath structures.The unique advantage of core-sheath structure is the potential to obtain a combination of two miscible or immisciblepolymers with different properties [2]. In this study, the coaxial electrospinning technique was used to produce thechitosan /ploy(ε-caprolactone)/sesame oil composite nanofibers in which chitosan formed the core layer and the ploy(ε-caprolactone)/sesame oil formed the shell layer
