An automatically controlled electrospinning system for large-area nanofibrous membrane preparation

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.
