Description

technical field [0001] The invention belongs to the field of nanometer materials, and in particular relates to a conjugated two-component solvent-free electrospun micro-nano fiber and a preparation method and device thereof. Background technique [0002] Electrospinning technology is a simple and effective method to prepare uniform and continuous one-dimensional micro-nanofibers. At present, through electrospinning technology, hundreds of polymers are prepared into micro-nano fibers. However, the preparation of these electrospun fibers mostly comes from solution electrospinning, that is, the polymer solution is stretched in a high-voltage electrostatic field, and the final solvent is volatilized to form fibers. The electrospun fibers prepared by solution electrospinning have fine diameter, good continuity and controllable morphology. However, the configuration of the spinning solution generally requires the use of a large amount of organic solvents, which account for more ...
