摘要
电纺丝作为一种多功能技术，已被广泛用于生成各种材料的纳米纤维。电纺丝还有助于教授从高分子化学到物理、安全和可持续发展等不同难度和学生参与程度的课题。只需花费不到 30 欧元，就能实现简单安全的动手实验/手动测定，以演示聚合物粘度和纳米纤维的排列和溶解性。学生们可以进一步研究（超）疏水性，甚至将包装废弃物循环利用为有用的过滤材料，还可以改进电纺丝装置，从手动测定到基于 Arduino 的廉价 3D 打印研究平台。此外，后者还可用于教师演示更具挑战性的实验，而使用商用注射泵也能轻松完成这些实验。
Electrospinning as a Fascinating Platform for Teaching Applied Polymer Science with Safe and Sustainable Experiments
Electrospinning has been widely used as a versatile technique to generate nanofibers of various materials. It is also helpful in teaching topics ranging from macromolecular chemistry to physics, safety, and sustainability at various levels of difficulty and student involvement. Simple and safe hands-on experiments/manual assays can be realized for less than 30 euros to demonstrate polymer viscosity and nanofiber alignment and solubility. Students can further study (super)hydrophobicity and even upcycle packaging waste into useful filter materials but also improve the electrospinning setup from a manual assay to an inexpensive Arduino-based 3D printed research platform. Alternatively, the latter can be used for teacher demonstrations of more challenging experiments that can also be easily done using a commercial syringe-pump.
期刊介绍：
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
