“…The decrease in the dielectric constant resulted from the dipolar polarization of CN groups, as well as the interfacial polarization between the BN-PRd platelets and NBR matrix that cannot be maintained as frequency increased. 18,33 The tanδ values of pure NBR, NBR composites filled with BN, and NBR composites filled with BN-PRd are exhibited in Figure 8C,D 1)). 12,37-39…”

“…16 Two-dimensional hexagonal BN platelets, also known as white graphite, are often used to improve the thermal conductivities of polymeric matrices due to their elevated λ value (250-300 W/mK), superior oxidation resistance, ultra-high breakdown strength (794 mV/ mm), low dielectric constant ($4), and good aspect ratio. 18 However, inorganic BN platelets often agglomerate in polymeric matrices via Van der Waals forces due to their large surface energies. Therefore, the formation of effective thermal conduction networks of BN platelets in composites remains challenging.…”

Hexagonal boron nitride (BN) platelets, also known as white graphite, are often used to improve the thermal conductivities of polymeric matrices. Due to the poor interfacial compatibility between BN platelets and polymeric matrices, in this study, polyrhodanine (PRd) was used to modify BN platelets and prepared functionalized BN-PRd platelets, thereby enhancing the interfacial interaction between the thermal conductive filler and polymeric matrix. Then, BN-PRd platelets were dispersed into the nitrile butadiene rubber (NBR) matrix to yield high thermally conductive compos-

“…Among ceramic fillers, h-BN has high TC, high chemical stability, large aspect ratio while possessing lowest dielectric constant among ceramic fillers (~4) and being a perfect electrical insulator (σ = 10 −11 S•cm −1 ) due to its large band gap. Therefore, all these merits turn h-BN into a promising candidate for utilization in electronic packaging materials [32,[47][48][49][50]. Since h-BN is regarded as an anisotropic filler with distinctive difference in its in-plane and out-of-plane TCs, the TC of the h-BN-reinforced polymer composite is also affected by filler's orientation, filler-filler and filler-polymer interfacial properties [51].…”

Ever-increasing significance of composite materials with high thermal conductivity, low thermal expansion coefficient and high optical bandgap over the last decade, have proved their indispensable roles in a wide range of applications. Hexagonal boron nitride (h-BN), a layered material having a high thermal conductivity along the planes and the band gap of 5.9 eV, has always been a promising candidate to provide superior heat transfer with minimal phonon scattering through the system. Hence, extensive researches have been devoted to improving the thermal conductivity of different matrices by using h-BN fillers. Apart from that, lubrication property of h-BN has also been extensively researched, demonstrating the effectivity of this layered structure in reduction of friction coefficient, increasing wear resistance and cost-effectivity of the process. Herein, an in-depth discussion of thermal and tribological properties of the reinforced composite by h-BN will be provided, focusing on the recent progress and future trends.

“…In order to solve this matter, kinds of current covalent and noncovalent methods to modify BN had been widely discussed. Bio‐inspired dopamine (PDA) and polyetherimide (PEI) were the most common modifiers 29,30 . Chen et al exploited dopamine (DA) to supply a polymer coating (PDA) on BN surface to improve the dispersion and compatibility of the polymer matrix (A‐ph/CE) 31 .…”

At present, the application of epoxy resin and its composites was severely restricted by its disadvantages of intrinsic brittleness after curing, poor fatigue strength, and low fracture energy. In order to improve its mechanical performances and broaden its applied range, the modified boron nitride‐basalt fiber/epoxy resin composite laminates (EP‐BF/mBN) were successfully prepared via a hot‐press process by using BF as reinforcement of epoxy resin composites and BN nanosheets treated by codeposition of PDA and PEI as toughening agent. The effects of the concentration of modified BN solution on the mechanical properties of the composites were studied in terms of flexural strength, flexural modulus, the interlaminar shear strength (ILSS), and the mode II interlaminar fracture toughness (GIIC). When 6 g L−1 modified BN solution was added, the flexural strength, flexural modulus, ILSS, and GIIC increased by 12.7%, 10.4%, 37.0%, 62.3%, respectively. And flexural strength, flexural modulus, ILSS, and GIIC approached to 894.6 MPa, 34.6 GPa, 60.4 MPa, and 483.9 J m−2, respectively, which was 20.0%, 10.7%, 38.9%, and 68.9% higher than that of EP‐BF at −60°C, suggesting that EP‐BF/mBN even had better mechanical performances at low temperature, which would be widely used in more fields in the future.
