“…The dielectric breakdown test of polymers usually involve multiple samples because of statistical variations in the recorded values of breakdown strength. A study has reported that even though the samples are identical, the extent of breakdown strength of the specimens may be significantly different . The dielectric breakdown data are known to be in good agreement with the Weibull distribution, which can be expressed by eq.…”

In this study, nanofillers composed of alumina, titania, and organoclay were separately embedded in 50% polypropylene (PP) and 50% ethylene propylene diene monomer (EPDM) blends. Several formulations of PP/EPDM nanocomposites were prepared using an internal mixer and were molded using a compression mold to produce test samples. The effects of filler loading (2, 4, 6, and 8 vol %) on the dielectric breakdown strength, dielectric properties, hydrophobicity, and flammability were determined. The addition of nanofillers improved the breakdown strength (up to 2 vol %) and increased the dielectric constant and dielectric loss of the PP/EPDM nanocomposites. The hydrophobicity of PP/EPDM/Al2O3 increased, whereas the hydrophilicity of PP/EPDM/TiO2 and PP/EPDM/organoclay increased. Flammability test results showed that PP/EPDM/TiO2 had a lower burning rate than PP/EPDM/Al2O3 and PP/EPDM/organoclay. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 41184.

“…The interplanar distance between graphene sheets stacked regularly had a d ‐spacing of 0.35 nm. Pristine GNPs showed a sharper and stronger diffraction peak than TA‐GNPs, strongly indicating that TA‐GNPs are less crystalline than GNPs because the adhesion of TA molecules onto GNPs decreased the regularity of graphite flakes …”

Enhancing thermal conductivity of polymeric nanocomposites remains a great challenge because of the poor compatibility between nanofillers and the polymeric matrix and the aggregation effect of nanofillers. We report the enhanced thermal conductivity of poly(lactic acid) (PLA)-based nanocomposites by incorporation of graphite nanoplatelets functionalized by tannic acid. Graphite nanoplatelets (GNPs) were noncovalently functionalized with tannic acid (TA) by van der Waals forces and p-p interaction without perturbing the conjugated sp 2 network, thus preserving the high thermal conductivity of GNPs. PLA-based nanocomposites with different contents of TA-functionalized GNPs (TA-GNPs) were prepared and characterized, and the influences of TA-GNPs content on the morphologies, mechanical properties, and thermal properties of the composites were investigated in detail. TA-GNPs remarkably improved the thermal conductivity of PLA up to 0.77 W/(m K), showing its high potential as a thermally conductive filler for polymer-based nanocomposites.

“…The high thermally conductive fillers contain metal powders, such as copper [6], aluminum [7,8] and silver particles [9], ceramic fillers such as boron nitride (BN) [10,11], aluminum nitride (AlN) [12], silicon nitride (Si 3 N 4 ) [13] and carbon-based fillers such as graphite [14,15], carbon nanotubes (CNTs) [16,17] and even graphite nano-sheets [18].…”
