基于不同组分的核芯材料制备多层核-壳结构复合材料的独特优势在于可实现对复合材料的尺寸、形态及组成的有效调控,从而获得多类具有新颖结构和性能的多功能复合材料。根据常见核芯材料的组成类型,将核芯材料分为无机纳米颗粒(如磁性微粒、二氧化硅、纳米金属、半导体等)和聚合物微球(如聚苯乙烯和聚合物微凝胶)两类,并分别从多层核-壳复合微球材料的制备方法特点及其性能等方面进行分析和阐述。
The unique advantages of core-shell materials based on different components in preparing multi-layered core-shell composite materials lie in the effective control of the size, shape and composition of the composite materials, so as to obtain various types of multifunctional composite materials with novel structures and properties . According to the composition of common core materials, the core materials are divided into inorganic nanoparticles (such as magnetic particles, silica, nano-metals, semiconductors, etc.) and polymer microspheres (such as polystyrene and polymer microgels) Two kinds of methods were respectively analyzed and elaborated from the aspects of the preparation methods and properties of multi-layer core-shell composite microspheres.
