Abstract

The comprehensive teaching experiment presented herein exhibits strong interdisciplinary integration, practical relevance, and application potential, making it a suitable experimental teaching program for undergraduates majoring in materials chemistry, polymer science, and other related fields. This experiment successfully integrates organic synthesis techniques, nanomaterial preparation methods, and polymer hydrogel performance characterization skills acquired by undergraduate students, which is critical for enhancing their comprehensive experimental operation capabilities. Through hands-on practice, students not only enhance their ability to solve complex experimental problems but also develop innovative thinking and scientific research literacy. Taking the application requirements of multifunctional hydrogels in the biomedical field as the starting point, the experiment guides students to deeply explore the intrinsic relationship between the chemical structure and properties of materials, thereby establishing a systematic cognitive framework. Throughout the experiment, students complete the synthesis of dopamine methacrylamide (DMA), the preparation of molybdenum disulfide (MoS₂) nanosheets, and the construction of MoS₂ composite hydrogels (MoS₂@DAS), followed by evaluating the mechanical, adhesive, catalytic, and photothermal properties of the hydrogels via various characterization methods. The teacher–student interactive teaching mode runs through the entire process of experimental preparation, implementation, and summary, positively expanding students’ theoretical knowledge, improving practical skills, and fostering innovation ability.

MoS2@DAS跨学科教学中的水凝胶实验：提高大学生科研素养

综合教学实验具有较强的跨学科整合性、实践性和应用潜力，适合材料化学、高分子科学等相关专业的本科生进行实验教学。本实验成功地将本科学生所学的有机合成技术、纳米材料制备方法和聚合物水凝胶性能表征技能结合起来，对提高其综合实验操作能力至关重要。通过动手实践，不仅提高了学生解决复杂实验问题的能力，而且培养了学生的创新思维和科研素养。本实验以多功能水凝胶在生物医学领域的应用需求为出发点，引导学生深入探索材料的化学结构与性能之间的内在关系，从而建立系统的认知框架。在整个实验过程中，学生完成了多巴胺甲基丙烯酰胺（DMA）的合成，二硫化钼（MoS2）纳米片的制备，以及二硫化钼复合水凝胶的构建（MoS2@DAS），随后通过各种表征方法评估水凝胶的机械，粘合，催化和光热性能。师生互动教学模式贯穿于实验准备、实施、总结的全过程，积极拓展学生的理论知识，提高实践技能，培养创新能力。

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.
