Synthesis of Amphiphilic Functional Core-shell Structures Polymeric Particles and Application as Catalyst Scaffold of Noble Metal Nanoparticles

Abstract

采用亲水单体与疏水单体直接共聚的方法可以在没有添加任何稳定剂的条件下一步合成两亲性核-壳结构功能性聚合物微球,并且两亲性核-壳结构功能性聚合物微球在作为贵金属纳米粒子载体方面具有显著优势。要使金属纳米粒子固定在微球的壳层并保持复合微球的稳定性,一般要求两亲性核-壳结构聚合物微球的壳层带有可以与金属离子产生静电作用或者具有孤对电子可以与金属离子产生络合作用的功能基团。亲水性单体甲基丙烯酸二甲氨基乙酯(DMAEMA)可以在酸性条件下被质子化成带正电的季铵盐与AuCl4-通过静电作用结合在一起,并且DMAEMA上的氮原子带有孤对电子可以与Ag+络合,因此,本论文采用亲水单体DMAEMA与疏水单体tB...Amphiphilic functional polymeric particles with core-shell structures can be synthesized directly by copolymerization of hydrophilic monomers and hydrophobic monomers without addition of any stabilizers. They have significant advantages as the carriers of noble metal nanoparticles. In order to immobilize and stabilize metal nanoparticles on the surface of the core-shell particles, the surface func...学位:理学硕士院系专业:材料学院_高分子化学与物理学号:2072010115011
