“…The polymer composites using inorganic nanomaterials as fillers have attracted much attention owing to their distinctive properties and various potential applications in the construction, automotive, aerospace and electronics industries. [5][6][7][8] In order to enhance the functionality and performance of a polymer nanocomposites, thermally conductive inorganic fillers like silicon carbide, [9] aluminum nitride, [10] aluminum oxide, [11] boron nitride, [12] etc., and metal oxide fillers such as SiO 2 and TiO 2 have been explored. [13,14] Noble metals such as gold and silver can also be used, however with limited applications due its expensive nature.…”

Recently, boron nitride (BN) based materials have received significant attention in both academic and industrial sectors due to its interesting properties like large energy band gap, good resistance to oxidation, excellent thermal conductivity, thermal stability, chemical inertness, significant mechanical property and widespread applications. This review article deals with the preparation and properties of boron nitride and its nanocomposites with various polymers. Diverse polymers have been explored for the preparation of boron nitride filled polymer nanocomposites by adopting different mixing methods. Properties of the resulting polymer nanocomposites mainly depend up on filler size and dispersion, mixing conditions and type of interaction between polymer matrix and the filler. Herein, the structure, preparation and properties of various boron nitride based polymer nanocomposites are reviewed in detail along with a brief overview of different classes of BN nanomaterials.

“…During self-polymerization, the nanoller was found to change, which signies that the h-BN surface was effectively coated with polydopamine. 223 Further, several polymer nanocomposites with different concentrations (0 wt%, 2 wt%, 5 wt%, 10 wt%, 15 wt%, and 20 wt%) of nanoller were synthesized using a simple curing casting method. Among all the nanocomposites, the TC of the A-ph/CE/h-BN@PDA composite sample (with 20 wt% h-BN@PDA) was increased to 0.71 W m À1 K À1 .…”

“…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 . Wu et al used a combination of mechanical exfoliation and chemical modification to modify h‐BN, and the result showed that the introduction of PEI enhanced the dispersibility and compatibility of h‐BN in EP, furthermore, the crosslink density of epoxy resin also improved 32 .…”

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.
