Abstract
The invention discloses a receiving device for electrostatic spinning. The receiving device for electrostatic spinning comprises a motor, a box body, a bracket, a rotary shaft and a roller, wherein the bracket is arranged on the box body, the roller is provided with a plurality of punching holes, the motor is connected with one end of the rotary shaft through a belt, the other end of the rotary shaft is connected with one end of the roller, the other end of the roller is connected with a fixing device, the exterior of the rotary shaft is sheathed with a protecting device, the protecting device is arranged on the bracket, the roller is in a cylinder shape, the surface of the roller is uniformly provided with the punching holes, each punching hole is in a circular hole shape, the diameter of each hole is 1-3mm, the distance between the two adjacent punching holes is 1-3mm, and the diameter of the roller is 1-20cm. The preparation method comprises the following steps of 1, preparation of solution; 2, preparation for spinning; 3, spinning. The receiving device for electrostatic spinning has the advantage that the prepared fiber bracket has the fiber orienting and large-hole structure; during electrostatic spinning, the orienting degree of fiber in the circular holes of the roller is high, and the orienting degree of the surrounding of the circular hole is low.
Description
technical field [0001] The invention relates to the technical field of electrospinning preparation, in particular to a receiving device for electrospinning. Background technique [0002] Electrospinning technology is a technology that can continuously prepare nanofibers. In terms of biomedicine, because of the high porosity and large specific surface area of the prepared fibrous membrane, it has very unique advantages as a tissue engineering scaffold. The primary goal of tissue engineering scaffolds is to realize the function of extracellular matrix (ECM) in a three-dimensional space, guide the migration and growth of surrounding tissues and cells, or provide suitable conditions for the growth of cells planted in the porous structure of the scaffold. environment, to ensure the adhesion, proliferation, differentiation and migration of cells, and the natural ECM is mainly composed of tens to hundreds of nanometer protein fibers intertwined to form a three-dimensional networ...
