摘　　要：以50%肼为插层剂,高岭土为原料,采用超声辅助插层法,成功地将肼分子插入到高岭土结构层间,制得高岭土/肼插层复合材料。采用红外光谱(FT-IR)、X射线衍射(XRD)、热重分析(TG)等对复合材料的结构进行了表征。结果表明:利用超声辅助制备高岭土/肼插层复合材料不仅可以大大缩短插层反应时间。插层后的高岭土粒径变小,层间距变大。With natural mineral kaolin as raw material and 50% hydration hydrazine as intercalation chemicals, the authors intercalate hydrazine molecules（N2H4）between the layers of kaolin successfully by means of ultrasonic technique. The complex materials are characterized with the help of XRD, FT-IR and TG. The results show that the preparation of kaolin/hydrazine intercalation complex materials assisted by ultrasonic technique can significantly reduce the reaction time. After being intercalated, the grain diameter of kaolin reduces while the basal spacing increases.
