“…For this reason, polymers containing thermal conductive fillers are emerging as one of the most economical and effective ways to cope with thermal management issues. [7][8][9] To the best of my knowledge, many thermal conductivity composites have been prepared filled with different kinds of fillers (carbon fiber, [10] carbon nanotubes, [11][12][13] AlN, [14][15][16][17] SiC, [18,19] Si 3 N 4 , [20,21] and graphite, [22][23][24] etc.) Boron nitride (BN) possesses many excellent properties, such as high thermal stability, electrical insulation and chemical resistance, and a relatively high thermal conductivity coefficient, and it has been widely used in the preparation of high thermal conductivity composites.…”

Boron nitride (BN) micro particles modified by silane coupling agent, γ‐aminopropyl triethoxy silane (KH550), are employed to prepare BN/epoxy resin (EP) thermal conductivity composites. The thermal conductivity coefficient of the composites with 60% mass fraction of modified BN is 1.052 W/mK, five times higher than that of native EP (0.202 W/mK). The mechanical properties of the composites are optimal with 10 wt% BN. The thermal decomposition temperature, dielectric constant, and dielectric loss increase with the addition of BN. For a given BN loading, the surface modification of BN by KH550 exhibits a positive effect on the thermal conductivity and mechanical properties of the BN/EP composites.

“…Recent studies have shown that by incorporation thermal conductivity fillers, such as carbon nanotube [11][12][13][14], boron nitride nanotube [15], silicon nitride [16,17], silicon carbide [18,19], graphite [20][21][22], and carbon black [23,24], etc., into polymers can improve the thermal conductivities. In our previous work [25][26][27][28], various thermal conductivity composites have been fabricated by adding different thermally conductive fillers.…”

The volume fraction of functionalized graphene nanoplatelets (GNPs) influencing on the thermal conductivities of GNPs/polyphenylene sulfide (GNPs/PPS) composites are investigated. Results reveal that a great improvement of the thermal conductivities with the addition of functionalized GNPs, and the thermal conductivity of the GNPs/PPS composite is 4.414 W/mK with 29.3 vol% functionalized GNPs, 19 times higher than that of the pure PPS matrix. The significantly high improvement of the thermal conductivities is ascribed to good thermal transmission through GNPs networks in the PPS matrix, following a thermal percolation behavior. Meantime, the GNPs have strong ability to generate continuous thermally conductive chains, and the formation of thermally conductive networks becomes much easier. POLYM.

Polymer/Boron Nitride Nanocomposite Materials for Superior Thermal Transport Performance

et al. 2012

Lightweight nanocomposites with superior thermal transport properties promise great application potential, [1][2][3][4] for which there has been extensive development effort. [5][6][7][8] Among widely pursued nanoscale fillers in such composites are carbon nanomaterials. For example, carbon nanotubes are extremely thermally conductive at the individual-nanotube level. [9,10] More recently, single-and fewer-layer graphene sheets have been shown to be even more advantageous than carbon nanotubes, [11][12][13][14][15] especially for their uses in polymeric nanocomposites of high thermal conductivity. [16][17][18][19][20][21][22][23][24][25] Hexagonal boron nitride (BN) is structurally analogous to graphite (Scheme 1) and has equally good thermal transport properties. [26,27] In fact, bulk BN has traditionally been considered as a material of choice in thermal-management applications. [28][29][30][31][32][33][34][35][36][37] In recent years both BN nanotubes and sheets have attracted growing attention for thermal transport and other uses. For example, Li and Hsu prepared composite films of polyimide with micro-and nanosized BN, including BN "nanoflakes", for which thermal conductivities of up to 1.2 W m À1 K À1 at 30 wt % BN loading were obtained. [28,29] Sato et al. also studied polyimide composites with hexagonal BN as filler, and films containing 30 and 60 vol % BN exhibited thermal conductivities of 3 and 7 W m À1 K À1 , respectively. [30] Wattanakul et al. found similar thermal conductivities in epoxy composites with 33 vol % hexagonal BN. [31] These results suggest that the thermal transport performance of polymer composites with BN is generally poorer than with graphene sheets as filler. Therefore, there are major challenges and also opportunities in the development of polymer/ BN nanocomposites with much improved performance, especially with respect to the need for lightweight composite materials with extreme ratios of thermal to electrical conductivity to exploit the electrically insulating nature of BN.In this study we exfoliated hexagonal BN in organic medium to give sheets of nanoscale thickness and dispersed the resulting BN nanosheets in poly(vinyl alcohol), PVA, and epoxy matrices. Superior thermal transport performance was achieved in the polymer/BN nanocomposite films thus fabricated, and substantial performance enhancement through mechanical alignment of BN nanosheets embedded in PVA was found. The results demonstrate that BN sheets of nanoscale thickness may indeed hold promise for polymer nanocomposites with metal-like thermal transport performance, similar to what has already been achieved in polymer nanocomposites with fewer-layer graphene sheets. [23,25] Commercially acquired hexagonal BN was sonicated vigorously in isopropyl alcohol for both dispersion and exfoliation. An aliquot of the resulting suspension was used to prepare specimens for characterization of the BN sheets by microscopy and other techniques. Representative SEM images (Figure 1 a,b) suggest lateral sizes (edge-to-edge) of the ...
