“…The surface modification of the fillers could be due to the alleviated phonon scattering at the interface of the VMQ matrix and filler particle compared with that of the unmodified composites. In most cases, the phonon scattering at the interface of the matrix/filler restricts heat transfer and the poor interfacial adhesion between the matrix and the filler leads to large phonon scattering [17]. In this work, we confirmed that HBM can efficiently reduce the thermal conductivity of the composites and provide applications for preparing heat-resistant materials.…”

“…It could be attributed to the formation of BN‐g‐PA6, which improves the interfacial bonding between PA6 and BN and promotes the dispersion of BN in the matrix of PA6. Then, the strong interfacial bonding could decline the phonon scattering in the area of the interface, and the good dispersion could benefit the formation of the continuous thermal conductive paths or network at a relatively low filler loading.…”

Polyamide 6/boron nitride (PA6/BN) composites were synthesized via anionic ring‐opening polymerization using ε‐caprolactam as the monomer and functional boron nitride (f‐BN) as the thermal conductive filler. Besides the homopolymerized PA6, some PA6 molecule chains would grow from the f‐BN sheets through the “grafting from” strategy. Compared with unfunctional hexagonal BN (h‐BN), the introduction of f‐BN not only improved the dispersion of f‐BN in the matrix but also enhanced the interface bonding between f‐BN and PA6. The homogeneous dispersion of f‐BN in the PA6/f‐BN composite favored the formation of the continuous thermal conductive paths or network at a low f‐BN loading, and the good interface bonding reduced the phonon scattering in the interface, which improved the thermal conductivity (TC) of the PA6/f‐BN composite by 66.0% compared with that of the pure PA6, when only 5 wt% f‐BN was added. In contrast, with the same content of unfunctional h‐BN loading, the TC of the corresponding composite merely improved by 29.7%. Moreover, Young's modulus and yield strength of PA6/f‐BN composites had increased obviously with the introduction of f‐BN, whereas those of PA6/h‐BN composites showed small fluctuation with the same contents of BN.

“…The surface modification of BNNSs led to a meaningful improvement of the effective thermal conductivity. Generally, the phonon scattering at the interface of matrix/filler restricts heat transfer and a poor interfacial adhesion between the matrix and the fillers leading to a large phonon scattering . The surface functionalization of fillers attributed to an alleviated phonon scattering at the interface of HDPE matrix and SC‐BNNSs particles, compared with that of HDPE/BNNSs nanocomposites .…”

Functionalization of boron nitride nanosheets by diazonium salt for preparation of nanocomposites with high‐density polyethylene

Functionalization of boron nitride nanosheets (BNNSs)has always been a challenge due to its chemical inertness and anti-oxidative properties. In a concentrated base environment, the B-N bonds on the surface of BNNSs were broken to produce a large number of B-OH and N-H functional groups. Afterwards, aniline carbocation produced by decomposition of the diazonium salt was utilized to achieve high grafting content of Ph-NH 2 groups onto the surface of BNNSs. Further, the amide reaction between amino and stearyl chloride verified the reactivity of Ph-NH 2 groups on the surface of BNNSs, with the result that BNNSs were abundantly decorated by aliphatic chains at 22.9 wt% grafting yield. The surface aliphatic chains of BNNSs strongly improved the interfacial adhesion between the High-density polyethylene (HDPE) matrix and the filler and provided an excellent dispersion of SC-BNNSs in the HDPE matrix. Therefore, HDPE/SC-BNNSs nanocomposites showed improved thermal stability, thermal conductivity, neutron shielding property and flexural modulus with no apparent reduction in tensile strength. When filler content exceeded 5 wt%, the HDPE/SC-BNNSs nanocomposites showed a higher thermal decomposition temperature than the composites with pristine BNNSs fillers. POLYM.
