Introduction of the interfacial layer between filler and matrix: An effective approach towards developing high thermal conductive dielectric composite

In the development of high-performance electronic devices, high thermal conductive dielectric composites are crucial. For PTFE-based dielectric composites, enhancing thermal conductivity while maintaining low dielectric properties remains a challenge. The key issue lies in the high interfacial thermal resistance between fillers and the PTFE matrix, which restricts the improvement of thermal conductivity. This paper focuses on introducing an interfacial layer between the filler and the matrix as an effective approach. By constructing a SiO2 interfacial layer between hBN and PTFE, we formed hBN@SiO2 core-shell structured fillers and then prepared hBN@SiO2/PTFE composites. This method significantly reduces the interfacial thermal resistance. Consequently, the thermal conductivity of the composite reaches 1.40 W/(m·K), the coefficient of thermal expansion decreases, and it still keeps a low dielectric constant of 3.9 and low dielectric loss of 1 × 10−4. This study provides an innovative and effective way for the development of high thermal conductive dielectric composites, which is of great significance for high-power and high-frequency applications. © 2025 Elsevier Ltd and Techna Group S.r.l.
