Convenient and integration fabrication process is a key issue for the application of functional nanofibers.A surface func-tionalization method was developed based on coaxial elec-trospinning to produce ultraviolet(UV)protection nanofibers.The titanium dioxide(TiO2)nanoparticles suspension was delivered through the shell channel of the coaxial spinneret,by which the ag-gregation of TiO2 nanoparticles was overcome and the distribution uniformity on the surface of polyethylene oxide(PEO)nanofiber was obtained.With the content of TiO2 increasing from 0 to 3％(mass fraction),the average diameter of nanofibers increased from(380±30)nm to(480±100)nm.The surface functionalization can be realized during the electrospinning process to gain PEO/TiO2 composite nanofibers directly.The uniform distribution of TiO2 nanoparticles on the surface of nanofibers enhanced the UV absorp-tion and resistance performance.The maximum UV protection factor(UPF)value of composite nanofibers reaches 2751.This work presented a novel surface-functionalized way for the preparation of composite nanofiber,which has great application potential in the field of micro/nano system integration fabrication.
