- Abstract
In this study, multi-walled carbon nanotubes (MWCNTs) and boron nitride (BN) were functionalized with cetyltrimethylammonium bromide (CTAB) at both pH 5.5 and pH 11. These MWCNT-CTAB and BN-CTAB particles used to prepare the composites were dispersed in a bisphenol A (DGEBA)-type epoxy resin (ER) system at room temperature. The TGA analysis showed that the BN composite can significantly improve the thermal stability of neat ER at temperatures above 400 °C. The curing degrees of the nanocomposites were calculated to be approximately the same values as neat ER using the Beer-Lambert law from FTIR spectra. The best electrical conductivity of the composites obtained was 3.10 × 10−3 S/cm for ER/MWCNT-CTAB (pH 5.5). The surface hardness, Young's modulus, and tensile strength of the composites were examined. The surface hardness values of the ER/MWCNT-CTAB composites were higher than those of the other composites. The composite morphology was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). POLYM. COMPOS., 37:3423-3432, 2016. © 2015 Society of Plastics Engineers
