导电ZAO纳米晶的超声鄄模板法合成、表征及应用

采用超声-模板法高效合成出了分散好、导电性能优良的白色掺铝氧化锌(ZAO)纳米晶, 通过TEM、XRD、FT-IR、TG-DTA、UV-Vis等手段对产物形貌、结构及前驱物的热性质等进行了研究, 并研究了Al2O3掺入量与ZAO的电阻率、紫外-可见光谱吸收峰位置、能带带宽之间的关系. 将制得的导电ZAO纳米晶加入到抗静电涂料体系中, 不仅使涂料具有颜色浅、易于调色及导电性好等优点, 而且还大大提高了涂料的抗紫外等性能.

Characterizations and Application of Conductive ZAO Nanocrystals Prepared by Ultrasonic-Template Method

The white zinc aluminium oxide (ZAO) nanocrystals with excellent dispersity and electrical conductivity were efficiently synthesized by the ultrasonic-template method. The morphologies, structures of the ZAO nanocrystals andthe thermochemistry of the precursorwere researchedbyTEM,XRD, FT-IR, TG-DTA, and UV-Vis, etc. The relationships of Al2O3 addition quantity with the resistivity, UV-Vis absorption wavelength, and energy band gap of ZAO nanocrystals were also studied. The ZAO nanocrystals were added to the anlistatig-coatings system, and the obtained coating’s color was easy to be modulated, its electrical conductivity and UV-absorption were also obviously improved.
