Heat transfer nanolubricant and nanogrease based on carbon nanotube

摘要

In this paper, we report the effort to prepare a stable and homogeneous heat transfer nanolubricant and nanogrease in the oils (e.g. DURASYN~® 166) with the motivation of enhancing its properties such as thermal conductivity and lubricity. The process of making these fluids involves the dispersion of carbon nanoparticles into the oil through intermittent sonication and the use of additives such as surfactants. The rheology data indicats that the nanolubricant and nanogrease are non Newtonian fluids although the base DURASYN~® 166 oil is Newtonian fluid. The good characteristic results of the carbon nanotube greases are also reported.
