Electro-spinning device for preparing porous nano-fibre

Abstract

The invention discloses an electro-spinning installation for the preparation of porous nano-fiber bracket, which comprises a frame, an electrostatic voltage generating plant and at least one liquid supply device. The frame is provided with a fiber collection device and at least one splash head. The splash head and the liquid supply device are in mutual communication. The electrostatic voltage generating device is respectively in electric connection with the fiber collection device and the splash head, which is characterized in that a central control system is also comprised. The splash head is provided with a transverse adjusting device. The transverse adjusting device, the electrostatic voltage generating device, the fiber collection device and the liquid supply device four of them are all in electric connection with the central control system. Thus the device has the advantages that because the splash head is provided with the transverse adjusting device, and the transverse adjusting device, the electrostatic voltage generating device, the fiber collection device and the liquid supply device four of them are all in electric connection with the central control system, the splash head can be in automatic control of the horizontal displacement of the splash head along the rotation of a roller. Therefore, the nano-fiber met different needs and with specific shapes can be prepared.

Description

technical field [0001] The invention relates to a novel material and a device for preparing biological materials, in particular to an electrospinning device for preparing a porous nanofiber support. Background technique [0002] Electrospinning technology is considered to be an ideal method to prepare continuous nanoscale fibers, so it has been widely used in filter materials, wound dressings, nanocomposites and sensors. The use of electrospinning technology can prepare fibrous polymer scaffolds with fiber diameters ranging from 3nm to 5μm in different shapes, and design and adjust according to the requirements of the structural properties of the required materials, making this technology in the field of bioengineering such as preparing bionic Both functionalized and functionalized tissue engineering scaffolds have been extensively studied. This is because cells have a certain shape and direction when they grow naturally, such as nerve cells, muscle cells, and endothelial c...

Problems solved by technology

The jet stream oscillates and becomes unstable under the action of a high-voltage electric field, resulting in irregular spiral motion with extremely high frequency. In the high-speed oscillation, the jet stream is rapidly thinned, and the solvent is also rapidly volatilized, finally forming a micron to nanometer-scale fibers, so that polymer fibers in the form of non-woven fabrics are obtained on the receiving plate; however, many nanofibers produced by traditional electrospinning devices are arranged in a messy manner and cannot be adjusted, so it is impossible to prepare a scaffold of a specific shape suitable for cell growth
