- Abstract
- Abstract― ABS/MWNT nanocomposites were prepared by using MWNT wrapped with SAN through melt compounding. Effect of wrapping of MWNT by SAN on the morphology, mechanical and electrical properties of ABS/MWNT were analyzed. It was found that SAN could wrap MWNT effectively indicated by the increased thickness after wrapping, which is presumably due to helical structure of polyacrylonitrile component in a block copolymer of SAN. MWNT was observed to be dispersed more evenly in ABS matrix by SAN wrapping, which resulted in improved tensile properties of the composites. On the other hand, there was little effect on the impact strength and electrical properties of ABS having inherently high impact strength.
