Ultrasonic assistant electrostatic spinning device

Abstract

The invention discloses an ultrasonic assistant electrostatic spinning device which comprises an ultrasonic assistant system, a supply system, a parameter control system, a collecting system and a glass box body, wherein the ultrasonic assistant system comprises an ultrasonic generator, an ultrasonic transducer, a hollow water tank and a low-temperature constant-temperature water bath tank; the ultrasonic transducer is fixed on the outer side of the hollow water tank and is controlled by the ultrasonic generator; the hollow water tank is connected with fixing screw nuts; two low-temperature constant-temperature water bath pipeline connectors are arranged at a side part of the hollow water tank; a water outlet is formed in the upper part of the hollow water tank; the supply system adopts a micro-injection pump to quantitatively push a boosting injector I; the head part of the boosting injector I is connected with the head part of a boosting injector II through a silicone tube; the handle part of the boosting injector II is connected with the handle part of a sample injector and is placed and fixed inside an outer thread straight tube, and the sample injector can be pushed at a same speed; the parameter control system is used for controlling the ambient temperature and the spinning voltage inside the glass box body; and the collecting disc of the collecting system is grounded and is driven by a motor to rotate. The ultrasonic assistant electrostatic spinning device is applied to long-term turbid liquid electrostatic pinning operation.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to an electrospinning device with an ultrasonic auxiliary function and an absolute advantage in electrospinning of suspension liquid. Background technique [0002] Electrospinning technology, as a one-dimensional nanofiber construction technology with simple device, low cost and wide variety of spinnable materials, has attracted extensive research and attention in the field of material science and technology in the world in the past ten years. [0003] The term electrospinning originates from electrospinning or earlier electrostatics spinning, which is generally referred to as electrospinning, electrospinning, electrospinning, etc. in China. In 1934, Formalas invented an experimental device for preparing polymer fibers by electrostatic force and applied for a patent. His patent disclosed how the polymer solution forms a jet between electrodes. This is the first patent describing in detai...

AI Technical Summary

Problems solved by technology

Traditional electrospinning devices require nanoparticle precursors and polymer templates to be dissolved in the solution, and the polymer templates are removed during the calcination process after spinning to form nanoparticles, which limits the types of nanoparticles that can be loaded
