Abstract

A series of silver nanoparticles surface-coated with di-n-dodecyldithiophosphate, di-n-cetyldithiophosphate, or di-n-octadecyldithiophosphate have been prepared and have good dispersity in alkanes or kerosene. Stable silver nanofluids can be formed in alkanes or kerosene with the surface-coated silver nanoparticles. Thermal stability of the silver nanofluids has been measured at different temperatures. The effects of the silver nanoparticles on the thermal oxidation of kerosene have been investigated at different temperatures. The coatings can be released from the surface of the silver nanoparticles above 150°C, giving oxygen access to the silver core and inhibiting the kerosene oxidized by oxygen.

摘要

已制备了一系列表面包覆二正十二烷基二硫代磷酸酯、二正十六烷基二硫代磷酸酯或二正十八烷基二硫代磷酸酯的银纳米粒子，它们在烷烃或煤油中具有良好的分散性。表面包覆的银纳米粒子可以在烷烃或煤油中形成稳定的银纳米流体。在不同温度下测量了银纳米流体的热稳定性。在不同温度下研究了银纳米粒子对煤油热氧化的影响。涂层在 150°C 以上时可以从银纳米粒子表面释放出来，使氧气进入银核并抑制被氧气氧化的煤油。
