| 为推动化学、材料科学与工程等相关专业实验教学与前沿科学研究的深度融合,本文设计了一项以聚合物半导体纳米薄膜制备与力学性能表征为主题的研究性综合实验。基于柔性电子技术中聚合物半导体薄膜力学性能的最新研究成果,本实验以聚(9,9-二辛基芴)(PFO)及其增塑可拉伸聚合物半导体纳米薄膜为研究对象,针对传统力学测试方法及其相关样品制备难以直接评价聚合物半导体纳米薄膜本征力学性质的问题,采用H型支架制备无支撑半导体薄膜,原位量化薄膜的力学拉伸性能,并揭示了拉伸形变对发光二极管器件性能的影响机制,开展了聚合物半导体薄膜的拉伸测试与教学实验研究。教学实践表明,将科技前沿成果引入实验教学设计,通过理论授课与实验操作相结合,使学生全程参与实验过程,能够强化科研思维训练,提升实践创新能力,将抽象概念与具体实验相结合,激发了学生的学习兴趣与创新思维,培养了实验设计能力与仪器操作水平。本实验设计为将材料化学类科研成果转化为实验教学资源提供了可借鉴的路径。 |

| . To promote the deep integration of experimental teaching with cutting-edge scientific research in disciplines such as chemistry, materials science and engineering, this paper designs a research-oriented comprehensive experiment centered on the preparation and mechanical characterization of polymer semiconductor nanofilms. Based on the latest research findings on the mechanical properties of polymer semiconductor nanofilms in flexible electronics, this experiment takes poly(9,9-dioctylfluorene) (PFO) and its plasticized stretchable polymer semiconductor nanofilms as the research subjects. To address the difficulty of directly evaluating the intrinsic mechanical properties of polymer semiconductor nanofilms using traditional mechanical testing methods and their associated sample preparation techniques, an H-type support substrate is employed to fabricate free-standing polymer semiconductor films, enabling in-situ quantification of the mechanical tensile properties of the films. Furthermore, the mechanism by which tensile deformation affects the performance of light-emitting diode devices is revealed, and tensile testing and teaching experiments on polymer semiconductor films are conducted. Teaching practice demonstrates that introducing cutting-edge research achievements into experimental teaching design—combining theoretical instruction with hands-on experimental operations and engaging students throughout the entire experimental process—can strengthen scientific research thinking training, enhance practical innovation capabilities, integrate abstract concepts with concrete experiments, stimulate students" learning interest and innovative thinking, and cultivate experimental design skills and instrument operation proficiency. This experimental design provides a replicable pathway for transforming research achievements in materials chemistry into experimental teaching resources. |
