Summary: Electrospinning is increasingly popular for producing fibrous assemblies with high surface area, and coaxial electrospinning has emerged as a modified version to address limitations of traditional methods. This review discusses the mechanism of coaxial electrospinning, operational parameters for fabricating continuous fibers, and modifications to improve fiber properties. Examples of diverse applications and current limitations of coaxial electrospinning are also included for discussion.

Summary: Core-sheath fibers composed of crystalline polymer (PEO) in the core and amorphous polymers (PS and PMMA) in the sheath were fabricated through coaxial electrospinning. PEO crystallization behavior was influenced by the hard confinement of the immobile sheath, resulting in decreased crystallite size, degree of crystallinity, and crystallization kinetics.

Summary: In this study, core-sheath nanofibers composed of polycaprolactone (PCL) polymer were successfully fabricated, with Simvastatin (SIM) confined to the core and nanohydroxyapatite (nHA) loaded on the surface. The nanofibers exhibited cylindrical morphology, and their core-sheath structure was confirmed using Transmission Electron Microscope. SIM was found to be in an amorphous state within the nanofibers, and excellent chemical compatibility was observed among SIM, nHA, and PCL through Fourier Transform InfraRed spectroscopy. The core-sheath nanofibers showed sustained release of SIM for 672 hours, and they demonstrated the most favorable cell proliferation behavior.

Summary: In this study, core-sheath structure fibers composed of PVDF and NPs as the shell layer and PCL as the core layer were prepared using electrospinning. The addition of PVDF and NPs increased the polar phase of the fibers, and PCL improved their mechanical properties. The core-sheath structure fibers demonstrated enhanced mechanical and piezoelectric properties, making them suitable for wearable electronics applications.

Summary: One-dimensional core-sheath nanofibers consisting of platinum-loaded ceria sheath on mesoporous silica core were successfully synthesized and used as catalysts for the reverse water gas shift reaction. The core-sheath nanofibers had a core diameter of 100-300 nm and a sheath thickness of 40-100 nm with a Pt loading of 0.5 wt.%. The impregnated catalyst, Pt-CeO2 NF@mesoporous SiO2, showed the best catalytic performance with a CO2 conversion of 8.9% at 350 degrees C.

Summary: In this study, core-sheath nanofiber membranes (CSNFMs) with silver nanoparticles embedding in the polylactic acid nanofiber sheath and hyaluronic acid in the nanofiber core were prepared. The CSNFMs functioned as barrier membranes to reduce fibroblast penetration without hampering nutrient transports to prevent post-operative peritendinous adhesion. The CSNFM with thin-sheath and Ag NPs showed antibacterial activity with low cytotoxicity and exhibited the highest efficacy in reducing fibroblast attachment in vitro.
