Abstract

The effects of the aspect ratio of multi-walled carbon nanotube (MWNT) on viscoelastic properties and flammability properties of PS/MWNT nanocomposites are studied with two different MWNTs having average aspect ratios of 49 and 150. While no significant effects of the aspect ratio on thermal stability of PS/MWNT nanocomposites are observed, the storage modulus and complex viscosity of larger aspect ratio particle additive PS/MWNT are much larger at the same fixed mass concentration. The mass loss rate is also more reduced for the larger aspect ratio MWNT nanocomposites. These results show that the addition of MWNT having a larger aspect ratio leads to enhance flammability reduction.
