摘    要:以低分子量聚丙烯酸(PAA)为高分子模板构建自组装体系,合成核-壳结构的PAA/PbCrO4纳米颗粒.通过TEM、XRD、FT-IR、UV-vis、荧光光谱等表征手段对产物的结构、形貌与光学性能进行研究.结果表明:PAA通过羧基与Pb2+的配位作用包覆在PbCrO4纳米颗粒表面,形成核-壳结构,内核PbCrO4尺寸为50~100 nm,为单斜晶系;外壳PAA层厚20 nm.与普通PbCrO4体相材料相比,产物在829~854 cm-1红外吸收峰变宽,紫外与荧光光谱产生了"蓝移",表现出纳米粒子所具有的特殊光学现象.

关 键 词:聚丙烯酸  模板  铬酸铅  复合纳米颗粒

Abstract:PAA/PbCrO4 composite nanoparticles with core-shell structure were successfully synthesized by using polyacrylic acid as the template.The products were characterized by TEM,XRD,FT-IR,UV-vis and fluorescence spectroscopy.The results indicated that PAA was modified on the surface of PbCrO4 nanoparticles to form core-shell structure through the coordination between the carboxyl and Pb2+.The thickness of polymer shells was around 20nm and the PbCrO4 core was monoclinic structure with a grain size of 50~100nm.The...
Keywords:polyacrylic acid  template  PbCrO4  composite nanoparticle
