RESEARCH TO USE MULTI-WALLED CARBON NANOTUBES TO IMPROVE HEAT TRANSFER ENERGY

Abstract

Multi-walled carbon nanotubes (MWCNTs) are a type of material that has a
lot of structural features as well as outstanding properties that no material is
available. These include higher conductivity, better thermal conductivity, higher
mechanical strength than conventional materials, so MWCNTs have been used in
many fields that have been applied in practice, in particular. is in the field of heat
transfer. The MWCNTs used are a very good heat sink because they are capable of
absorbing the heat generated by the engine or CPU. However, with the structure
of coaxial interlocking graphene tubes making the MWCNTs material quite
chemically inert, the immediate use of the material actually makes it difficult.
Therefore, it is necessary to denaturation of MWCNTs, use strong acids such as a
mixture of H2SO4/HNO3 or a strong KOH base to bind functional groups to the
surface of MWCNTs. Then, the activity of the material will be higher and easy to
use in practical applications, thereby creating heat dissipation fluid containing
multi-walled carbon nanotubes.
