The invention relates to a centrifugal electrostatic spinning device, which comprises a frame. A rotary swinging cylinder made of a metal net is vertically and rotationally arranged on the frame. The top of the rotary swinging cylinder is provided with a feed inlet for being in conduction connection with a spinning solution conduit. The centrifugal electrostatic spinning device adopts the rotary swinging cylinder made of the metal net, and thus, the rotary swinging cylinder can be also used as an electrode and a spray nozzle of the electrostatic spinning device. The rotary swinging cylinder is made of the metal net, and thus, the number of meshes which are equivalent to spinneret orifices of the conventional spray nozzle is greatly increased and the working efficiency of the electrostatic spinning device is improved. Moreover, the rotary swinging cylinder rotates when working, so that a spinning solution can be swung out by a centrifugal force, the blockage of the meshes, namely the spinneret orifices of the conventional spray nozzle, is effectively avoided, and the production efficiency of the electrostatic spinning device is further improved. The centrifugal electrostatic spinning device can be used for scale production.
Description
technical field [0001] The invention relates to the field of textiles and materials, in particular to a centrifugal electrostatic spinning device. Background technique [0002] With the development of nanotechnology, electrospinning technology, as an effective and practical method, has received extensive attention in the field of nanomaterials research. As people's demand for nanofibers continues to increase, researchers from various countries have explored a variety of methods for preparing nanofibers, among which electrospinning is considered to be the simplest and most effective method for preparing nanofibers, and there are currently 30 methods A variety of polymers have successfully produced ultrafine fibers by this method, with the smallest diameter reaching tens of nanometers. Electrospinning includes two types: solution electrospinning and melt electrospinning. Most of the researches on electrospinning focus on solution electrospinning, but there are few researches ...
