Electrostatic spinning receiving device

Abstract

The invention discloses an electrostatic spinning receiving device, which comprises a water pipe, a water tank, syringe needles, an grounding electrode, non-woven fabric wet tissue, a circulating water tank and a roller, wherein the water tank is arranged above the circulating water tank; the water pipe is communicated with the water tank; the water pipe is fixedly provided with the syringe needles; the roller is arranged on the circulating water tank; the non-woven fabric wet tissue covers the roller; the roller is connected with the grounding electrode; and the circulating water tank is provided with a water tank water discharging outlet. When the electrostatic spinning receiving device disclosed by the invention is applied, the non-woven fabric wet tissue overlaid on the roller can fully contact with the water surface of the water tank; when the roller continuously rotates, the non-woven fabric wet tissue also can continuously adsorb moisture; and a circulating process can be formed through the water tank on the upper end of the roller and the water tank water discharging outlet on the bottom of the water tank. Therefore, DMAc and LiCl can be guaranteed to be adsorbed by constant moisture, fiber redissolution can be prevented, or the phenomenon that the fiber morphology is damaged to become a cast film can be prevented.

Description

technical field [0001] The invention belongs to the field of electrospinning, and in particular relates to an electrospinning receiving device capable of circulating a water bath cylinder. Background technique [0002] Electrospinning technology is currently one of the most direct and basic methods for preparing ultrafine fibers and nanofibers. The nanofibers prepared by it have large aspect ratio, large specific surface area, high porosity, high uniformity, and easy functionalization. Etc. [0003] Electrospinning is a technique commonly used in the preparation of a large number of one-dimensional nanomaterials in recent years, but there are still many basic problems to be solved when it is implemented on cotton fibers. On the one hand, one of the solvent components used is DMAc(N , N dimethylacetamide), it is difficult to completely volatilize naturally in the process, and the other part of LiCl cannot be effectively removed during the spinning process. When these two par...

[0003] Electrospinning is a technique commonly used in the preparation of a large number of one-dimensional nanomaterials in recent years, but there are still many basic problems to be solved when it is implemented on cotton fibers. On the one hand, one of the solvent components used is DMAc(N , N dimethylacetamide), it is difficult to completely volatilize naturally in the process, and the other part of LiCl cannot be effectively removed during the spinning process. When these two parts reach the collection end, they will reconstitute the composite solvent , causing a certain degree of redissolution to the newly formed fibers, or destroying the fiber morphology to become a cast film
