The thermal conductivity of rubber is very poor. But many fields need thermal conductive rubber materials to satisfy the requirement of application. Therefore

people pay more attention to the research of the thermal conductive rubber. In the present paper

the effects of the types

shape

particle size and the dispersion of filler in the rubber matrix

together with the interface bonding state between rubber and filler

on the thermal conductivity of rubber composites are summarized. The thermal conductive mechanism was analyzed from the experiments viewpoint

and the physical and mathematical models of the thermal conductive rubber

which could predict their thermal conductive performance

were also reviewed. At the same time

the advantages and disadvantages of these models and their applicable range were analyzed as well. In the last section

the application fields and the future development of thermal conductive rubber were also introduced.
