Multifunctional nanofiber membrane with anti-ultraviolet and thermal regulation fabricated by coaxial electrospinning

Ultraviolet radiation is extremely harmful to humans and often occurs in high-temperature weather. The development of intelligent textiles based on UV protection and thermal regulation is paramount. In this research, we use coaxial electrospinning technology to prepare anti-ultraviolet smart thermo-regulating nanofiber membranes. The zinc oxide (ZnO) and octadecane were incorporated into nanofibers with the polyacrylonitrile (PAN)/ZnO as sheath and the octadecane as core successfully. The composite nanofibers have excellent comprehensive properties, the highest melting enthalpy is 111.38 J/g, and the UPF value is 86.21. This multifunctional nanofiber membrane has broad prospects in outdoor products, electronic component protection, and military products.
