摘　　要：以碳酸钠为沉淀剂,以聚乙二醇1 000为修饰剂,采用简单的化学共沉淀方法制备了不同掺铝量的掺铝氧化锌(AZO)纳米粉体.用热重-分析仪(TG-DTA)、X-射线衍射仪(XRD)、X-射线光电子能谱仪(XPS)、元素分析仪(EDS)、描电子显微镜(SEM)和透射电子显微镜(TEM)等表征方法研究了不同铝掺杂量AZO的结构和形貌.研究结果显示:所制备的AZO纳米粉体为六方晶系氧化锌结构,颗粒分散性和结晶性较好,呈类球形.将所制备的AZO纳米粉体与聚丙烯酸树脂复合制成涂料,利用线棒涂膜技术在玻璃基底上制备了AZO/聚丙烯酸树脂复合涂层,对其进行隔热性能测试.结果表明,所制得的隔热涂层具有较好的隔热效果,有望在隔热领域得到应用.Sodium carbonate was chosen as precipitant and polyethylene glycol as the surfactant to prepared aluminum doped zinc oxide（AZO） nanopowder with different Al dosage by a simple precipitation method.The microstructure and morphology of different Al dosage AZO were systematically characterized by thermal analysis system（TG-DTA）,X-ray diffraction（XRD）,X-ray photoelectron spectroscopy（XPS）,energy dispersive spectrometry（EDS）,scanning electron microscopy（SEM） and transmission electron microscopy（TEM）.The experimental results showed that the AZO was spherical and had good dispersibility and excellent crystallinity.Moreover,the AZO was uniformly dispersed in commercial polyacrylic acid and coated onto flat glass plates by wire rod coating technology to generate AZO / polymer composite coating.The heat insulation performance of the composite coating was evaluated.The results revealed that the AZO / acrylic resin composite coating possessed a certain degree of heat insulation property,and was expected to apply in the field of heat insulation.
