固体聚离子液体的有序性表征

聚离子液体有序性表征聚离子液体有序性具体表征手段目录聚离子液体132聚离子液体自组装离子液体（IL）：是指由有机阳离子和无机阴离子组成的物质,一般认为其熔点低于100℃。聚离子液体(PIL)即是离子液体的聚合物，与离子液体相比最大的优点就是空间可控性。MecerreyesD.Polymericionicliquids:Broadeningthepropertiesandapplicationsofpolyelectrolytes[J].ProgressinPolymerScience,2011,36(12):1629-1648.1：聚离子液体聚离子液体的应用MecerreyesD.Polymericionicliquids:Broadeningthepropertiesandapplicationsofpolyelectrolytes[J].ProgressinPolymerScience,2011,36(12):1629-1648.2：聚离子液体自组装聚离子液体通常是一种两亲性高聚物，而后通过自组装方法纳米结构材料的制造引起了越来越大的兴趣。固定纳米结构的聚合物所合成聚离子液体嵌段共聚物自组装，微相分离成不同相态结构纳米结构的聚离子液体聚离子液体两亲性分子自组装成不同的有序液晶相结构所以我们有必要通过合适的表征手段对两亲性聚离子液体自组装后的局部有序性行为进行研究而且通过结构有序性的研究可以与聚离子液体的一些性质进行关联。直接cryo-TEMX-raydiffractionDifferentialscanningcalorimetryPolarizedopticalmicroscopy(POM)AFM间接6.smallangleX-rayscattering(SAXS)3：聚离子液体有序性具体表征手段dispersionpolymerization：Thepolymerizationproceededover24hatamonomerconcentrationof50g/Linaqueoussolutionsat70℃usingthewater-solublenonionicinitiator2,2-azobis[2-methyl-N-(2-hdroxyethyl)propionamide](VA86).1.Self-AssemblyofPoly(ionicliquid)s:Polymerization,MesostructureFormation,andDirectionalAlignmentinOneStepJiayinYuan,SebastianSoll,MarkusDrechsler,AxelH.E.M€uller,andMarkusAntonietti水溶液中乳液聚合分散的聚离子液体纳米粒子用冷沉淀-TEMXRD洋葱多层囊泡结构（接近球形）脂质单层囊泡结构（各向异性的刚性形态）演变成各向异性存有六方相态或者四方相态结构的纳米粒子。正方排列DSCPIL-C12Br是非晶的，对于C14,C16,C18分别在1,21,and35℃出现结晶的熔融吸热峰。5.InfluenceofAnionExchangeinSelf-AssemblingofPolymericIonicLiquidBlockCopolymersPedroMariaCarrasco,AlaitzRuizdeLuzuriaga,MariosConstantinou,ProkopiosGeorgopanos,SofiaRangou,ApostolosAvgeropoulos,NikolaosE.Zafeiropoulos,Hans-JurgeGrande,GermanCaba~nero,DavidMecerreyes,andIgnacioGarcia*AFM垂直于表面的柱状相生成smallangleX-rayscattering(SAXS)当X射线照射到试样上时，如果试样内部存在纳米尺度的电子密度不均匀区，则会在入射光束周围的小角度范围内（一般2

6º）出现散射X射线，这种现象称为X射线小角散射或小角X射线散射（SmallAngleX-rayScattering），简写为SAXS。其物理实质在于散射体和周围介质的电子云密度的差异。SAXS已成为研究亚微米级固态或液态结构的有力工具常见的溶致液晶种类lyotropicliquidcrystalrespectivelyforlamellar,Hexagonaland
