Nanocomposites, composed of organic and inorganic building blocks, can combine the properties from the parent constituents and generate new properties to meet current and future demands in functional materials. Recent developments in nanoparticle synthesis provide a plethora of inorganic building blocks, building the foundation for constructing hybrid nanocomposites with unlimited possibilities. The properties of nanocomposite materials depend not only on those of individual building blocks but also on their spatial organization at different length scales. Block copolymers, which microphase separate into various nanostructures, have shown their potential for organizing inorganic nanoparticles in bulk/thin films. Block copolymer-based supramolecules further provide more versatile routes to control spatial arrangement of the nanoparticles over multiple length scales. This review provides an overview of recent efforts to control the hierarchical assemblies in block copolymer-based hybrid nanocomposites.
纳米复合材料由有机和无机构建块组成,可以结合母体成分的特性并产生新的特性,以满足当前和未来对功能材料的需求。纳米粒子合成的最新进展提供了大量的无机构建块,为构建具有无限可能性的混合纳米复合材料奠定了基础。纳米复合材料的性质不仅取决于各个构建块的性质,还取决于它们在不同长度尺度上的空间组织。嵌段共聚物会微相分离成各种纳米结构,它们在大块/薄膜中组织无机纳米粒子的潜力已得到证明。基于嵌段共聚物的超分子进一步提供了更通用的方法来控制多个长度尺度上纳米粒子的空间排列。本文综述了近年来控制基于嵌段共聚物的混合纳米复合材料中分级组装的努力。
