Principle of non-solution contact electrospinning.

Self-designed reverse electric field electrospinning device and non-solution contact electrospinning device were employed to carry out a series of electrospinning experiments, and ANSYS finite element analysis software was used to simulate and analyze the field intensity distributions of the electrospinning setups, and thus to demonstrate the feasibility of non-solution contact electrostatic spinning technology theoretically and practically. The research results showed that, by using non-solution contact electrospinning technology, the nanofibers with narrow diameter distribution can also be obtained and no residual solvent, meanwhile the morphology of the nanofibers were same to that from conventional electrospinning technology, and the former has excellent safety property, which is expected to realize the production of nanofibers at industrial scale.
