Study of influence of carbon nanotubes on thermal conductive properties of thermal pastes

Many industrial sectors require efficient heat transfer to ensure safe and efficient operation of equipment. Thermal pastes are materials used to improve heat transfer between different surfaces. Recently, carbon nanotubes (CNTs) have become widely used in the field of electronics and microelectronics due to their unique physical and chemical properties. One of the areas where CNTs can be applied is thermal conductivity. In this study, the effect of carbon nanotubes on the thermal conductive properties of thermal pastes was investigated. In this paper, an experiment was conducted to evaluate the thermal stability and performanceimprovement of thermal pastes by adding carbon nanotubes. KPT-8 thermal paste with a density of 2.6 g/cm2 and thermal conductivity of 0.7 W/mK was used in the experiment. Thermal pastes are materials used to improve heat transfer between different surfaces. The results of the study showed that thermal paste with CNT additives has higher thermal conductivity than thermal paste without additives. This indicates that CNTs can be effectively used as additives to improve the thermal conductivity of thermal pastes. But when CNTs are used as additives in thermal pastes, certain problems may arise, such as the grouping of CNTs in the mass of the substance. This can lead to an uneven distribution of CNTs in the thermal paste and, as a consequence, to inhomogeneous thermal conductivity. The results emphasize the potential of carbon nanotubes as a promising additive for improving the thermal conductive properties of thermal pastes in various applications.
