The invention discloses an
electrospinning device for dynamically controlling the curvature of a
spinning solution and an application method for the
electrospinning device. The
electrospinning device comprises a solution supply
system, an
electric field control system, a
spinning solution curvature regulating
system and a
nanofiber collecting
system. The application method for the electrospinning device comprises the steps of adopting a first electrospinning method to regulate the curvature of the
spinning solution to a constant value so as to produce a narrowly distributed
nanofiber product, adopting a second electrospinning method to regulate the dynamic change of the curvature of the spinning solution so as to produce a multistage narrowly distributed
nanofiber product, or adopting a third electrospinning method to control an
electric field and regulate the curvature of the spinning solution so as to produce the narrowly distributed nanofiber product simultaneously. According to the electrospinning device for dynamically controlling the curvature of the spinning solution and the application method for the electrospinning device, since the spinning solution curvature regulating system is adopted, precise control over the curvature of the edge of the spinning solution can be achieved, the regulation of a batch
free solution level spinning process can be achieved, and the
critical voltage required for the free liquid surface for electrospinning can be reduced; besides, batch, stable and controllable production of the nanofiber products can be achieved, the curvature of the edge of the spinning solution can be dynamically regulated, and one-step production of aggregation of the multistage narrowly distributed nanofiber product is achieved.
