高岭土/TiO2纳米复合材料的制备与光学性质研究的开题报告摘要：本文研究了高岭土/TiO2纳米复合材料的制备方法和其光学性质。制备过程采用水热法合成，以高岭土为载体分别掺杂不同质量分数的钛酸四丁酯和乙醇水溶液，制备了一系列不同组成的高岭土/TiO2纳米复合材料。通过X射线衍射仪、扫描电子显微镜等技术对复合材料的形貌及晶体结构进行表征。结果表明，复合材料的晶粒大小随着钛酸四丁酯质量分数的增加而增大，纳米颗粒的分散效果也随之减弱。通过紫外-可见吸收光谱和荧光光谱分析样品的光学性质。当钛酸四丁酯的质量分数为5%时，复合材料表现出最强的吸光度和荧光强度，并显示出优异的荧光性能。关键词：高岭土/TiO2纳米复合材料，制备，光学性质。Abstract:Inthispaper,thepreparationmethodandopticalpropertiesofkaolin/TiO2nanocompositeswerestudied.Thepreparationprocesswassynthesizedbyhydrothermalmethod,usingkaolinasthecarrier,anddopingdifferentmassfractionsoftetrabutyltitaniumandethanolwatersolutionrespectively,toprepareaseriesofkaolin/TiO2nanocompositeswithdifferentcompositions.ThemorphologyandcrystalstructureofthecompositeswerecharacterizedbyX-raydiffractometryandscanningelectronmicroscopy.Theresultsshowthatthegrainsizeofthecompositesincreasesandthedispersioneffectofthenanoparticlesweakenswiththeincreaseoftetrabutyltitaniummassfraction.TheopticalpropertiesofthesampleswereanalyzedbyUV-visibleabsorptionspectrumandfluorescencespectrum.Whenthemassfractionoftetrabutyltitaniumwas5%,thecompositematerialshowedthestrongestabsorbanceandfluorescenceintensity,andexcellentfluorescenceperformancewasdisplayed.Keywords:kaolin/TiO2nanocomposites,preparation,opticalproperties.
