Macromolecular-scale electrospinning controlling inner topologic structure through a blowing air

Macromolecules are the foundation stone to construct a nanofiber in the electro-spinning. Their distribution and orientation greatly affect the product?s properties. In this paper, a rotary blowing air is used to control the radial topological structure of a nanofiber, and a macromolecule-scale inner structure can be designed. The influence of the flow properties on nanofibers? mechanical properties is studied experimentally.
