学士学位论文题目：溶剂热微乳法制备纳米碳酸锶及其表征姓名院系专业年级学号指导教师年月日溶剂热微乳法制备纳米碳酸锶及其表征摘要：本文以硝酸锶和碳酸铵为原料、CTAB(十六烷基三甲基溴化铵)/正丁醇/水/正庚烷微乳液为溶剂，利用溶剂热微乳法制备碳酸锶纳米材料。主要考察Wo的大小、反应温度T对碳酸锶结构和形貌的影响。采用X射线粉末衍射(XRD)、透射电镜(TEM)和傅立叶变换红外光谱(FI-IR)对产物进行了表征。结果表明，除了150℃条件外，不同条件下得到的碳酸锶粉体的晶型均为斜方晶系；在Wo=20时，反应温度为室温、120℃条件下制得的样品是由近似球形颗粒组成；反应温度为150℃得到的产品为棒状结构，表明反应温度对碳酸锶的形貌有影响。关键词：溶剂热微乳法；碳酸锶；纳米材料ResearchProgressofMicroemulsion-AssistedSolvothermalMethodforPreparingstrontiumcarbonateNanomaterials(SchoolofChemistryandMaterialsScienceLudongUniversityYantai264025)AbstractUsingstrontiumnitrateandammoniumcarbonateasstrontiumandcarbonatesource,cetyltrimethylammoniumbromide(CTAB)/n-butanol/H2O/heptaneassolvent,SrCO3nanomaterialsweresynthesizedbyMicroemulsion-assistedsolvothermalmethod.TheeffectsofWo(ratioofsurfactanttocosurfactant)andreactiontemperatureonthestructureandshapeofcrystalsweremainlyinvestigated.ThepurifiedSrCO3crystalswascharacterizedbyX-raydiffraction(XRD),fouriertransitioninfraredspectroscopy(FT-IR),andtransmissionelectronmicroscope(TEM).Theresultsshowedthatinaddditiontothereactiontemperatureof150℃,strontiumcarbonatenanomaterialssynthesizedunderotherconditionwereorthorhombiccrystal,andwhenWowasfixedas20,thesamplesconsistedofapproximatelysphericalparticlesatroomtemperatureand120℃,andtherod-likestructurewereobservedat150℃,WhichindicatedthemorphologyofSrCO3crystalswereaffectedbythereactiontemperature.KeyWordsMicroemulsion-assistedsolvothermalmethod;Strontiumcarbonate;Nanomaterials目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc232871285"1引言PAGEREF_Toc232871285\h1HYPERLINK\l"_Toc232871286"1.1纳米碳酸锶的性质PAGEREF_Toc232871286\h1HYPERLINK\l"_Toc232871287"1.2纳米碳酸锶的制备方法PAGEREF_Toc232871287\h1HYPERLINK\l"_Toc232871288"1.3溶剂热微乳法PAGEREF_Toc232871288\h3HYPERLINK\l"_Toc232871289"1.4溶剂热微乳法中影响纳米粒子制备的因素PAGEREF_Toc232871289\h4HYPERLINK\l"_Toc232871290"1.5选题的目的和意义PAGEREF_Toc232871290\h6HYPERLINK\l"_Toc232871291"2实验部分PAGEREF_Toc232871291\h6HYPERLINK\l"_Toc232
