Abstract

The invention discloses an electrospinning nanofiber membrane. Acrylate, acrylic acid and polyethylene glycol methacrylate are polymerized into a copolymer, and then a metal salt solvent is added to obtain a spinning solution, and the spinning solution is injected into the electrospinning film. Electrospinning was carried out in the silk device. In the present invention, under the premise of not obviously affecting the apparent morphology of nanofibers, the breaking strength of nanofiber membranes is effectively improved by 1-2 times; when the amount of copper chloride added is 10% of the amount of acrylic acid monomers in the polymer %, the mechanical properties of the nanofibrous membrane are the best, the breaking strength is 35.12MPa, and the breaking elongation is 26.91%.

Description

technical field [0001] The invention relates to the field of preparation and application of polymer materials, in particular to an electrospinning nanofiber membrane, a preparation method and an application thereof. Background technique [0002] Electrospinning, also known as electrospinning, is currently one of the most convenient and effective methods for preparing nanoscale or submicron fibers. It can prepare nanofiber membranes with large specific surface area, controllable morphology, and diverse components. Smooth surface, uniform distribution and other advantages. Therefore, electrospun fibers are widely used in the fields of biomedicine, optoelectronics, textile engineering, catalytic carriers, and wastewater treatment. However, the diameter of the fibers produced by electrospinning is usually several hundred nanometers, which makes the mechanical properties of the fibers generally poor, and it is difficult to apply to places with high mechanical properties, which g...
