ZnO纳米晶自组装微米球热控涂层制备与表征——介绍一个材料化学综合实验

Transformation of Satellite ZnO Thermal Control Coating Scientific Research into an Experiment for Laboratory Teaching

基于科教融合理念,将科研项目“ZnO基热控涂层的制备”转化为本科生实验,以有机胺辅助水热法制备的纳米ZnO为颜料,通过刮涂法获得热控涂层。实验具有航天国防背景特色,涉及化学、材料和能源等多学科交叉融合,具备新颖性、实用性及可操作性的特点。学生从颜料粉体合成、表征技术、涂层制备和光学性能测试全操作流程中接受基本科研训练,有利于培养学生实验操作技能、科研探索及创新能力,加深基础理论知识理解,增强家国情怀和激发科研兴趣。

Based on the concept of integration of science and education,the scientific research project“Nano-ZnO Pigment Thermal Control Coating”is transformed into an experiment in materials chemistry laboratory for undergraduates.Nano-ZnO prepared by organic amine-assisted hydrothermal method is used as the pigment,and the thermal control coating is obtained by the blade coating method.The experiment has the aerospace and defense background and covered chemistry,materials and energy disciplines which exhibited novelty,practicality and operability.Students can obtain basic scientific research training from the synthesis method and characterization technology of pigment powder,coating preparation and optical performance testing.It is conducive to cultivate students’home country feelings,laboratory skills,exploration and innovation ability,deepen the theoretical knowledge and stimulate students’interest in scientific research.
