According to the diameter distribution diagram of the nanofibers, it is found that the diameter of the coaxial nanofibers is significantly larger than that of the blended group. The reason may be that when preparing the coaxial nanofibers, more liquid is injected per unit time, which makes it form a larger liquid at the nozzle. Taylor cone, resulting in an increase in fiber diameter. Furthermore, as the proportion of GO increased, the diameter of the nanofibers decreased, which could be attributed to the enhancement of the conductivity of the solution by the addition of GO, which made the solution have stronger tension under the electric field and formed thinner fibers38.
