Description

technical field [0001] The invention relates to the technical field of electrospinning and nanometer material systems, and more particularly, relates to a device for large-scale production of nanofiber membranes. Background technique [0002] Electrospinning is a spinning method that makes polymer solution or melt produce Taylor cones under electrostatic action and is jet stretched into micron or nanoscale fibers. As early as 1934, Formhals had reported the invention of spinning by high-voltage electrostatic field in its patent US1975504. After nearly 80 years of development, electrospinning technology has become increasingly mature, and electrospun fibers of certain materials have even been put into application in the fields of separation and tissue engineering. However, for a long time, electrospinning has basically been a small-scale preparation mode, with low output and short supply. The inability to mass-produce has greatly hindered the development and popularization ...

Problems solved by technology

However, during its production, the polymer is in a heated melt state, which is easy to be oxidized and affects the quality, and the cost is high. It is not easy to achieve large-scale preparation, and it is not industrialized in the true sense.
