摘要

以

-二羟乙基-3-胺基丙酸甲酯单体和季戊四醇( 核) 为原料

采用“ 准一步法” 合成了具有端羟基的超支化聚胺酯( HPAE) 。采用凝胶色谱、红外光谱、核磁共振和热重分析等对其进行了结构表征及性能探究。再以HPAE 封装稀土粒子钕( Nd)

制备出Nd 复合纳米粒子

透射电镜( TEM) 分析结果表明:随着HPAE 代数增大

Nd 纳米颗粒粒径越均匀

分散度越好。

Abstract

The synthesis of a series of polydisperse hyperbranched poly( amine-ester) s based upon pentaerythritol ( as a core molecule) and

-diethylol-3-amine methylpropionate is described

proceeding in preudo-one-step manner .The molecular composition of HPAE was characterized by GPC

FT-IR

H NMR and TGA .The thermoset of hyperbranched poly( amine-ester) synthesized in this study becomes better as the generation increases .So

those materials may be modified to meet particular application .Then highly uniform and monodisperse Nd nanoparticles

protected by hyperbranched poly( amine-ester)

were prepared in aqueous solution .Transmission electron microscopy (TEM) has been used to study the structure and characterization of the nanocomposites .From which it showed that Nd nanoparticles were formed inside HPAE and the size distribution fits a lognormal distribution as the generation increases.Those excellent dispersivity and good results allow for a complete prepare of nanoparticles by simple precedure .
