“…This is a relatively straightforward method but the compression moulding process itself is not commercially significant and therefore of limited interest. Another approach is to construct a freestanding filler framework as the heat transfer network, such as a graphene aerogel [39][40][41], BNNS aerogel [42,43] or complex aerogel [9,[44][45][46], and then encasing the network in a thermosetting matrix such as epoxy. Jiang et al [9] prepared a cellulose nanofiber supported boron nitride aerogel via sol-gel and freeze-drying, followed by casting with epoxy.…”

Diglycidyl ethers of bisphenol-A (DGEBA)/methyl tetrahydrophthalic anhydride/polyethersulphone (PES) blends are prepared as matrix resins for thermally conductive composites using graphite nanoplatelets (GNPs) as the conductive component. The epoxy/PES blends form a network structure via reaction-induced phase separation (RIPS) during the curing process, and the GNPs are selectively localized in the PES phase and at the interface leading to a three-dimensional continuous filler network. With this unique structure, the thermal conductivity of the epoxy/PES/10 wt% GNPs composite is increased to 0.709 W m-1 K-1 , which is nearly 3.5 times that of the pure epoxy or a 52% increase compared to the epoxy/GNP composite without PES. In addition, it is found that the impact strength of the composite relative to the unfilled material is also improved.

Boron nitride (BN) is an eminent inorganic compound having many interesting characteristics such as improved oxidation resistance, mechanical strength, good thermal conductivity (TC), higher bandgap, high chemical stability, thermal stability, high hydrophobicity, and electrical insulation. The use of BN as a filler in polymers is a well‐established strategy to tailor the properties of polymer composites. Recent studies depict an interesting urge to reap the synergistic effect of various nanofillers with BN in the form of hybrids. Hence the consolidation of the works on BN based hybrid fillers would definitely attract researchers so that these new filler systems could be transformed into useful polymer nanocomposites in future. This review article focuses on the synthesis and characterization of various boron nitride based hybrids in detail. Moreover, the review also throws light on different BN hybrid reinforced polymer nanocomposites (PNCs) and their thermal, electrical, electronic as well as biomedical applications in a detailed manner. Thus the review anticipates serving as a tool toward understanding the recent trends in the field of boron nitride hybrid based ternary polymer composites.

“…However, most traditional epoxy thermosetting resin materials are amorphous polymers with low thermal conductivity (usually in the range of 0.17-0.21 W/ (mÁK)), which cannot meet the high-power thermal management requirements in a small space. [1,7,8] Adding fillers with high thermal conductivity is an effective way to improve the thermal conductivity of epoxy resin currently, including carbon nanotubes (CNT), graphite, [8][9]10,11] ceramic oxide (Al 2 O 3 , SiO 2 ) [12] and nitride (AlN, BN). [13][14]15,16] Among these materials, Hexagonal BN has been the preferred material used in thermal management applications because of low density, various forms, high mechanical strength, good thermal conductivity (320 W/ (mÁK)) and chemical stability, and inherent electrical insulation.…”

The high thermal conductivity epoxy resin composites filled with inorganic filler can improve the low thermal conductivity of epoxy resin. However, a large number of fillers with high thermal conductivity will reduce other properties of the composites, which limits their use under high voltage, high temperature and strong mechanical force during operation. In this study, the dopamine-modified BN (DBN) and k-DBN (DBN modified by coupling agent KH-560) were prepared by employed the dopamine with catechol groups and coupling agent to modify boron nitride. The thermal conductivity, thermal stability, and dielectric properties of composites with different contents of modified fillers were studied. The results showed that surface modification improved the dispersibility of BN in the resin matrix and compatibility with the resin. Among BN/EP, DBN/EP, k-DBN/EP composites, k-DBN/EP composites had the highest thermal conductivity at the same number of additions. When the k-DBN/EP content was 30 wt%, the thermal conductivity of the composite was 0.892 W/(mÁK), which was an increase of 25.5% compared with the BN/EP composite. The appropriate amount of BN filling (20 wt%) can improve the breakdown strength of the composite material.
