Description

technical field

[0001] The invention relates to a feeding device. More specifically, it relates to a continuity-compensated electrospinning feeding device. Background technique

[0002] Electrospinning, also known as electrospinning, refers to the fact that under the action of a high-voltage electric field, the charged polymer solution or melt forms a cone, the so-called "Taylor cone", and continues to increase the electric field strength, the polymer solution Or the melt will be ejected from the "Taylor cone", and the jet will oscillate under the action of the high-voltage electric field, resulting in irregular spiral motion with high frequency, resulting in the rapid thinning of the jet and the rapid volatilization of the solvent. Nano-scale fibers are scattered on the collection device in a random manner to form a micro-nano fiber film, or on a moving / rotating collection device, a micro-nano fiber film with a certain fiber orientation is formed. The obtained micro-nano f...
