Abstract
Multiwall carbon nanotubes have been dispersed homogeneously throughout pol ystyrene matrices by a simple solution-evaporation method without destroyin g the integrity of the nanotubes. Tensile tests on composite films show tha t 1 wt % nanotube additions result in 36%-42% and similar to 25% increases in elastic modulus and break stress, respectively, indicating significant l oad transfer across the nanotube-matrix interface. In situ transmission ele ctron microscopy studies provided information regarding composite deformati on mechanisms and interfacial bonding between the multiwall nanotubes and p olymer matrix.
