1 Thermal and Electrical Properties of Nanocomposites (Nanotube Greases) 

Characterization of selected four types of nanocomposites (carbon nanotube 

Hamilton-Crosser equation (Equation 19.3), knowing the base fluid thennalconduetivity k and the carbon nanotube thermal conductivity kp Fricke equation [31,32] 

The calculated TC is also listed in Table 19.5. The less than calculated thermal conductivity value demonstrates the existence of thermal contact resistance and lack of efficient nanotube-nanotube physical contacts in the greases [34,35]. 

There are several factors that are very crucial to the thermal performance of the nanocomposites (nanogreases), including the stability of the suspension, the size distribution of the nanotubes/particles, the agglomerations of the nanotubes/particles, and the interface between the nanotubes/particles and oil in the suspension [36].
