The essence of higher education is to cultivate innovative talents for the society. Hence, higher education institutions (HEIs), on the one hand, need to respond to social needs and government policies. On the other hand, they need to keep pace with the times and improve the details of teaching to improve the effectiveness of education. In this paper, several combination education examples in HEIs about safety education and innovation education are shown to encourage students to realize innovations in technique during their laboratory experiments on electrospinning. To obtain professional knowledge and traditional professional skills, students are taught to implement electrospinning, an advanced technique for treating polymers, in the research laboratory. Safety education is also taught, during which the students are encouraged to play their subjective roles and ponder on how to apply innovations for safe, effective, and innovative implementation. The students apply a series of small technological innovations for the spinneret, which is the most innovative part of an electrospinning system. They can modify the spinneret for safer, more energy-saving, and more convenient operations of the single-fluid blending, coaxial, triaxial, and side-by-side electrospinning processes. Moreover, the innovations can deepen their professional knowledge of electrospinning and stimulate their enjoyment of innovations. Safety education on electrospinning can be a powerful tool for promoting technological innovations in students and increasing their awareness of related safety issues. The reported protocols in this paper show a new way for conducting combined education in HEIs on advanced techniques.

“…In addition, specific surface area and pore volume are the key factors for VOC adsorption . While electrospun-activated carbon fibers are easier to obtain a large specific surface area, their fiber diameter is much smaller than that of the traditional commercial fiber. − The fibers are fabricated using polyacrylonitrile, pitch, and poly(vinyl alcohol) as precursors commonly, followed by electrospinning, stabilization, carbonization, and activation.…”

Rich chemical properties and a well-developed pore structure are the key factors of porous materials for gas storage. Herein, rich heteroatom-doped porous carbon nanofibers (U1K2-X) with a large surface area were prepared by electrospinning followed by potassium hydroxide (KOH) activation. Low-cost urea was chosen as the nitrogen source and structural guiding agent. U1K2-X have a high specific surface area (628–2688 m2 g–1), excellent pore volume (0.468–1.571 cm3 g–1), and abundant nitrogen (2.5–12.8 atom %) and oxygen (4.5–12.5 atom %) contents. Acetone and carbon dioxide were used as target adsorbents to evaluate the adsorption properties of U1K2-X by experiments. These U1K2-X exhibit excellent adsorption performance (260.03–955.74 mg g–1, 25 °C, 18 kPa) and multilayer adsorption (the adsorption layer number n > 2) for acetone, which is mainly attributed to the large specific surface area and pore volume. Besides this, the carbon dioxide uptake reached 2.73–3.34 mmol g–1 at 25 °C. This was attributed to the combination of high nitrogen–oxygen contents and microporous structure. Furthermore, U1K2-X show the desirable repeatability. This study provides a new direction for the preparation of heteroatom-doped porous carbon nanofibers, which will be a promising material for gas adsorption.

Electrospinning is a contemporary and effective technique for producing fine fibers with diameters as small as nanometers by using an electric field. These fibers have numerous industrial applications, including filtration, sensors, composite materials, and membranes. This study provides an overview of the electrospinning process and discusses a few applications of polyvinyl alcohol based electrospun nanofibers in the development of filters and sensors.
