With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have been proved to have potential advantages in environmental protection and resource conservation. Thermal management materials based on cellulose can not only recycle waste paper but also expand thermal management materials to different fields. In this experiment, the senior undergraduates cultivated the awareness of green environmental protection by extracting cellulose from waste paper and then completed the construction and performance exploration of thermal management materials under the guidance of teachers. The simple representations involved in this experiment can enable undergraduates to connect with the knowledge of analytical chemistry, polymer chemistry, and other subjects learned in the classroom and enable students to combine theory with practice. In addition, the positive feedback received from the students indicates that the experiment effectively serves as a compelling platform for teaching polymer chemistry and analytical chemistry and closely links the latest scientific research results with the laboratory experiments of undergraduate students. This work not only cultivates students’ awareness of environmental protection but also stimulates their interest in advanced materials, which can be used as a springboard for them to become material scientists in the future.

从废纸到纤维素：实用主义教育学中的化学技术培养环境意识

随着废纸的增加，环境污染和大气影响已成为全球性问题。废纸中含有的纤维素具有可再生、可生物降解的优点，可应用于多个领域，实现可持续发展。目前，热管理材料作为一种新型材料，已被证明在环境保护和资源节约方面具有潜在优势。基于纤维素的热管理材料不仅可以回收废纸，还可以将热管理材料扩展到不同的领域。在本次实验中，高年级本科生通过从废纸中提取纤维素，培养了绿色环保意识，进而在老师的指导下完成了热管理材料的构建和性能探索。本实验涉及的简单图示可以使本科生与课堂上学到的分析化学、高分子化学等学科知识联系起来，使学生理论联系实际。此外，学生的积极反馈表明，该实验有效地为高分子化学和分析化学教学提供了一个令人信服的平台，将最新的科研成果与本科生的实验室实验紧密联系起来。这项工作不仅培养了学生的环保意识，还激发了他们对先进材料的兴趣，可以作为他们未来成为材料科学家的跳板。
