ZnSe纳米粉体两步法制备及其纳米复合材料的研究的开题报告摘要本文介绍了一种用两步法制备ZnSe纳米粉体的方法，并研究了其在纳米复合材料中的应用。首先通过水热法制备出Zn(OH)2纳米片状前驱体，然后在无水环境下用硫化氢气体还原得到纯净的ZnSe纳米粉体。采用X射线衍射仪（XRD）、扫描电镜（SEM）和透射电镜（TEM）等测试手段对制备的ZnSe纳米粉体进行了表征，并研究了其在PMMA基质中的分散性能。实验结果表明，所制备的ZnSe纳米粉体具有良好的分散性能和稳定性，能够有效地与PMMA基质相容，制备出高性能的纳米复合材料。关键词：ZnSe纳米粉体；两步法制备；纳米复合材料；分散性能AbstractThispaperdescribesamethodforpreparingZnSenanocrystallinepowderusingatwo-stepprocessandinvestigatesitsapplicationinnanocomposites.First,Zn(OH)2nanosheetswerepreparedbyahydrothermalmethod,andthenpureZnSenanocrystallinepowderwassynthesizedbyreducingZn(OH)2withhydrogensulfidegasinadehydratedenvironment.ThepreparedZnSenanocrystallinepowderwascharacterizedbyX-raydiffraction(XRD),scanningelectronmicroscopy(SEM),andtransmissionelectronmicroscopy(TEM),anditsdispersibilityinPMMAmatrixwasstudied.TheexperimentalresultsshowthatthepreparedZnSenanocrystallinepowderhasgooddispersibilityandstability,andcanbeeffectivelycompatiblewithPMMAmatrixtopreparehigh-performancenanocomposites.Keywords:ZnSenanocrystallinepowder;two-stepmethod;nanocomposites;dispersibility
