Abstract: Based on the fact that the electrospinning device used in the experiment item of "one-dimensional nanofibers prepared by electrospinning method" is expensive and inconvenient, we self-constructed an "electrospinning" teaching device independently. According to the basic principle of electrospinning, the injection pump, high voltage power supply, receiving device, glass cover, thermometer and other single instruments were assembled properly. As a result, the electrospinning device features low price and easy operation. When the device is applied to teaching, the students represent a long effective participation time and high learning interest. The performance of the self -constructed electrospinning teaching device is similar to that of the complete set of electrospinning equipment in the market. It shows a high experimental repeatability, accurate experimental results and smooth surface of experiment products, which meets the requirements of experimental teaching. The accessories are easily purchased and assembled, which gives the self-constructed electrospinning device wide applications.
