    摘要: The present invention relates to a process for preparing a stable suspension of carbon nanoparticles in a hydrophilic thermal transfer fluid to enhance thermal conductive properties and other characteristics such as freezing point of an antifreeze coolant. The process involves the step of dispersing carbon nanoparticles directly into a mixture of a thermal transfer fluid and other additives in the present of surfactants with intermittent ultrasonication. The present invention also relates to the composition of a hydrophilic nanofluid, which comprises carbon nanoparticles, particularly carbon nanotubes, a hydrophilic thermal transfer fluid, and at least one surfactant. Addition of surfactants significantly increases the stability of nanoparticle dispersion.
