本文中首先以SiO2纳米粒子为核,通过脱水反应在SiO2纳米粒子表面接枝3-硅羟基-1-丙基磺酸(SIT),再通过一元弱碱解离反应,以离子键接枝反离子聚氧乙烯十八烷基胺(Eth-omeen18/25),所形成的有机/无机杂化纳米材料在室温下呈金黄色的透明液体状,称其为无溶剂纳米流体。单分散态无溶剂SiO2纳米流体中,SiO2含量达20wt%。其电导率达10-3S/cm,在电池电解液、质子导电等领域具有巨大的潜在应用价值。
In this paper, SiO2 nanoparticles were firstly used as the core to graft 3-silanol-1-propylsulfonic acid (SIT) on the surface of SiO2 nanoparticles by dehydration reaction, and then by ionic weak base dissociation reaction Ionic polyoxyethylene octadecylamine (Etho-omeen 18/25). The resulting organic / inorganic hybrid nanomaterials were golden yellow in liquid form at room temperature and were called solventless nanofluids. In monodisperse solvent-free SiO2 nanofluids, the SiO2 content reached 20% by weight. Its conductivity of 10-3S / cm, in the battery electrolyte, proton conductivity and other fields with great potential value.
