ABSTRACT:
The present invention relates to compositions of a nanofluid, which comprises a thermal transfer fluid and carbon nanoparticles. The nanofluid may be hydrophilic nanofluids, such as a coolant, or hydrophobic nanofluids, such as nanolubricants or nanogreases. In particular, the present invention provides a homogenous hydrophilic nanofluid, which contains soluble carbon nanotubes in the hydrophilic thermal transfer fluid. The present invention also provides a nanogrease, which is a sustainable dispersion of solid carbon nanotubes in a hydrophobic thermal transfer fluid. The solid carbon nanotubes function as both as a thickener to modulate viscosity and as a solid heat transfer medium to enhance thermal conductivity and high temperature resistance.
