有机-无机纳米颗粒离子化材料(NIMs)是由无机纳米颗粒核和与其以共价键相连的离子化有机齐聚物或低聚物的冠状层组成的有机-无机杂化材料。根据核和冠状层的几何和化学性质,如纳米核的尺寸、形状及含量,有机层的分子量及接枝度的不同,NIMs可以是从玻璃态固体到自由流动的流体,即纳米颗粒离子化流体(Nms)。液态有机-无机纳米颗粒离子化材料折射指数高,零蒸汽压,高的热导性,此外,液态有机-无机纳米颗粒离子化材料具有较高的化学和热稳定性,并具有离子导电性,因此在导电润滑剂、高效致冷剂、浸润蚀刻技术、能量供给、储存和生产及电解质等领域有潜在的应用。本文综述了液态有机-无机纳米颗粒离子化材料的合成方法、应用前景及结构性能研究进展,并总结了存在的问题,展望了未来研究和发展趋势。
Abstract:Organic-inorganic nanoparticle ionic materials (NIMs) are hybrid materials comprising a nanoparticle core functionized with a covalently tethered ionic corona. NIMs can be tailored over a broad range from glass solids to free flowing liquids by varying geometric and chemical characteristics of the core and corona such as content, size and shape of nanoparticles, molecular weight and grafting density. Liquid-like nanoparticle ionic materials have high-refractive-index, zero-vapor pressure, high heat conductivity. Besides, NIMs are chemically and thermally stable and ionically conductive. They are therefore excellent candidate in immersion photolithography, high-conductivity lubricants, high efficiency coolants, engergy supply, storage, production and so on. Progress in synthesis and applications of liquid-like nanoparticle ionic materials is reviewed in this review. And the problems and promising future are prospected.
