Abstract This paper demonstrates the universal character of nano-spheres, formed from block copolymers of poly(2-(dimethylamino)ethyl methacrylate)-block-polystyrene (PDMAEMA-b-PSt) via polymerization induced self-assembly (PISA), as multifunctional templates for tailored nanoparticles (NPs) synthesis. Due to the presence of basic amine groups located within the shell of spherical PDMAEMA-b-PSt copolymers nano-objects, three types of inorganic precursors were loaded into the shells through electrostatic interactions. Both redox-type and sol-gel chemistry were used to successfully immobilize the in situ formed gold, or silica and titania NPs, respectively. The hybrids could be potentially used as catalysts or dielectric materials.

用于纳米粒子定制合成的多功能 PISA 模板

摘要 本文论证了由聚（2-（二甲氨基）乙基甲基丙烯酸乙酯）-嵌段聚苯乙烯（PDMAEMA-b-PSt）嵌段共聚物通过聚合诱导自组装（PISA）形成的纳米球的通用特性，作为多功能用于定制纳米颗粒 (NPs) 合成的模板。由于位于球形 PDMAEMA-b-PSt 共聚物纳米物体壳内的碱性胺基团的存在，三种类型的无机前体通过静电相互作用加载到壳中。氧化还原型和溶胶-凝胶化学均用于成功固定原位形成的金或二氧化硅和二氧化钛 NPs。杂化材料有可能用作催化剂或介电材料。
