Continuously superior-strong carbon nanofibers by additive nanostructuring and carbonization of polyacrylonitrile jetting.

ABSTRACT: Carbon nanofibers show the advantages of scale effects on electrical and mechanical properties for applications such as aerospace^1,2, automotive^3,4, and energy^5,6, but have to confront the challenge of maximizing the role of scale effects. Here, a method of additive nanostructuring and carbonization of polyacrylonitrile (PAN) jetting for the nano-forming of carbon fibers is developed by understanding the electrostatic submicro-initiation of a PAN jetting, altering the microstructure of PAN-based jetting fibers at the nanoscale and implementing subsequent carbonization of PAN jetting nanofiber. Using this method of additive nanostructuring and carbonization in combination with the radial distribution pattern of shear stress, we find that the conformation of
