Abstract

In this article, the SiO ₂ nanoparticles were used as the core, 3-(trihydroxysilyl)-1-propane-sulfonic acid was covalently grafted on to the surface of SiO ₂ via the dehydration reaction, and then polyoxyethylene octadecylamine (Ethomeen 18/25) was introduced to the surface of modified nanoparticles by electrovalent bonding. The organic/inorganic hybrid nanomaterials exist as golden yellow transparent liquid at room temperature, that is called solvent-free nanofluids. The SiO ₂ nanoparticles aremono-disperse in the hybrid nanomaterials system. The content of SiO ₂ nanoparticles reaches up to 20w%t. The conductivity reacheses 10 ^-3S/cm. It exhibits great potential application values in proton conductivity and the battery electrolyte and so on.
