Abstract: Multi-walled carbon nanotube (MWCNT)/poly (methyl methacrylate) composites were prepared and their mechanical and physical properties were examined. An amphiphilic copolymer was used to aid in dispersing the MWCNTs throughout the composite. It was found that the use of this copolymer resulted in a good dispersal of the MWCNTs without drastically affecting the molecular weights of the composites, so it was concluded that the observed improvements in mechanical properties of the composites were due to the MWCNTs. Since the nanotubes that were used were short in length, the electrical and thermal conductivities were not as high as desired.
