High thermal conductivity with electrically insulating substrates and thermal interface materials are in a great demand for high density and high power electronic packaging applications. The choice of ceramic-polymer hybrid films
provide many advantage in electrical and thermal behaviour
due its intrinsic nature of high thermal conductivity and high breakdown voltage, environmental and thermal stability. This work present the preparation hybrid films with mechanically exfoliated h-BN ceramic sheets and PVA polymer, and the effect of exfoliation, solid loading, particle sizes, compression pressures on the composite films were investigated. And the results are compared with the theoretical models like Arithmetic and Wiener equations that frequently used in the two phase mixture composites.
