Abstract
In this work, experimental and theoretical analysis of the microstructure and mechanical properties of carbon nanotube (CNT)/Acrylonitrile–butadiene–styrene (ABS) nanocomposite were conducted. In addition, the thermal degradation behavior of the nanocomposite as function of CNT was investigated. CNT/ABS nanocomposites filled with up to 10 wt% CNT were prepared by melt mixing followed by compression molding. Due to the compatibility between the CNT and the styrene-acrylonitrile (SAN) part of the ABS matrix, excellent dispersion with good interfacial adhesion at the CNT/SAN interface was observed. This microstructure was found to significantly improve the nanocomposites' tensile strength and Young's modulus. Both the volume exclusion electrical percolation model and the Cox tensile modulus model expected that the aspect ratio of the nanofiller after melt mixing is about 80. This value is consistent with the experimentally measured value for the same type of nanotubes in literature.
