“…These reports and the present work show significantly higher values than reported for BNNTs dispersed into a polymer matrix . The improved breakdown strength and reduced coefficient of thermal expansion, also reported by Zhi et al , illustrates additional multifunctional improvements obtained with electrically insulating, thermally conductive BNNT‐polymer composites.…”

“…Recent works are addressing this limitation and, with the availability of new commercial BNNTs , there are increased opportunities to study and exploit the properties of BNNTs. The combination of electrical insulation and thermal conductivity is one case where BNNTs offer a clear advantage for application to thermal interface materials and electrically insulating substrates/packaging materials or heat transfer fluids .…”

The sheets were either collected directly during synthesis or produced by dispersion and filtration. Differences between the effective thermal conductivities of filtrationproduced BNNT buckypaper (~1.5 W m -1 K -1) and lower-density as-synthesized sheets (~0.75 W m -1 K -1 ), which are both porous materials, were primarily due to their density. The measured results indicate similar thermal conductivity, in the range of 7 to 12 W m -1 K -1, for the BNNT network in these sheets. High BNNT-content composites (~30 wt.% BNNTs) produced by epoxy impregnation of the porous BNNT network gave 2 to 3 W m -1 K -1 , more than 10 the baseline epoxy. The combination of manufacturability, thermal conductivity, and electrical insulation offers exciting potential for electrically insulating, thermally conductive coatings and packaging.

Ever since the discovery of polymer composites, its potential has been anticipated for numerous applications in various fields such as microelectronics, automobiles, and industrial applications. In this paper, we review filler reinforced polymer composites for its enormous potential in microelectronic applications. The interface and compatibility between matrix and filler have a significant role in property alteration of a polymer nanocomposites. Ceramic reinforced polymeric nanocomposites are promising candidate dielectric materials for several micro‐ and nano‐electronic devices. Because of its synergistic effect like high thermal conductivity, low thermal expansion, and dielectric constant of ceramic fillers with the polymer matrix, the resultant nanocomposites have high dielectric breakdown strength. The thermal and dielectric properties are discussed in the view of filler alignment techniques and its effect on the composites. Furthermore, the effect of various surface modified filler materials in polymer matrix, concepts of network forming using filler, and benefits of filler alignment are also discussed in this work. As a whole, this review article addresses the overall view to novice researchers on various properties such as thermal and dielectric properties of polymer matrix composites and direction for future research to be carried out.

“…A novel strategy was designed to enhance thermal conductivity of epoxy composites by filling hybrid 2D boron nitride nanosheets (BNNSs) and 1D boron nitride nanotubes (BNNTs) [98]. The thermal conductivity of epoxy composites with 1-pyrenebutyric acid functionalized BNNTs/BNNSs hybrid fillers was up to 0.47 W/m⋅K at 2 wt% filler loading, higher than that with individual 1-pyrenebutyric acid functionalized BNNTs or BNNSs fillers ( Figure 21).…”

With the rapid development of electronic industry, heat dissipation issue becomes more and more important. Thermal functional composites (TFCs) are usually binary composites, filled with thermal conductive additives (nanomaterials) in matrix, and the composites show good thermal performance. The theoretical and experimental results show that the filler shape is one of the most important but easily overlooked factors. In this article, we provide a systematic review of the effect of the filler shape on the thermal conductivity of TFCs, and the heat transfer enhancement based on synergistic effect is also summed up. Finally, the future trends of further improving thermal properties of TFCs are predicted.
