Abstract

An automatic electrostatic spinning control system for large-area preparation of a nanofiber membrane comprises a device cabinet, a spinning syringe needle, a nanofiber receiving device, a bath heater and a humidifier. The device cabinet is provided with a spinning syringe needle transmission device, large-area preparation of the nanofiber membrane is achieved through a horizontal transmission system, a vertical transmission system can automatically adjust the distance between a spinning syringe needle and a receiving device; the spinning solution injection end of the spinning syringe needle is connected with a plastic needle cylinder fixed to a constant flow injection pump through a Lure fitting and a polymer tube with flexibility, and the needle tip portion of the spinning syringe needle is connected with a high-voltage power source through a high voltage resistant line with a clamp; the temperature / humidity is kept within the range of the device through a temperature / humidity controller maintaining device. The electrostatic spinning system can achieve large-area preparation of the nanofiber membrane, the spinning process can be performed in the accurate and controllable temperature / humidity environment, and the purposes of uniform fiber distribution and consistent orientation in the fiber membrane can be achieved.

Description

technical field [0001] The invention relates to the technical field of electrospinning systems, in particular to an automatically controlled electrospinning system for preparing nanofiber membranes in large areas, which relates to the preparation of polymers and inorganic non-metallic nanofiber membranes. Background technique [0002] Nanofiber, as a kind of wire-like material with a diameter of nanoscale and relatively large length and diameter, has many unique properties, and has received more and more attention in the fields of information, biology, environment, and energy. [0003] Generally, the methods for preparing nanofibers mainly include template method, phase separation method, self-assembly method, melt blown method and electrospinning method. Among them, compared with other preparation methods, the electrospinning method has the advantages of simple equipment, easy operation and universal applicability, and is currently a widely used preparation method for obtai...
