Load transfer and deformation mechanisms in carbon nanotube-polystyrene composites
نویسندگان
چکیده
Multiwall carbon nanotubes have been dispersed homogeneously throughout polystyrene matrices by a simple solution-evaporation method without destroying the integrity of the nanotubes. Tensile tests on composite films show that 1 wt % nanotube additions result in 36%–42% and ;25% increases in elastic modulus and break stress, respectively, indicating significant load transfer across the nanotube-matrix interface. In situ transmission electron microscopy studies provided information regarding composite deformation mechanisms and interfacial bonding between the multiwall nanotubes and polymer matrix. © 2000 American Institute of Physics. @S0003-6951~00!04120-6#

In-situ transmission electron microscopy studies of polymer-carbon nanotube composite deformation.
This paper demonstrates the viability of in-situ transmission electron microscopy for studying the deformation mechanisms of polymer nano-composites. In-situ straining studies are performed on carbon multiwalled nanotube (MWNT)-polystyrene composite films. The experiments show that load transfer across the nanotube-polystyrene interface is operative well into the plastic deformation regime of t...

Load transfer and mechanical strength of reinforced polymers are fundamental to developing advanced composites. This paper demonstrates enhanced load transfer and mechanical strength due to synergistic effects in binary mixtures of nano-carbon/polymer composites. Different compositional mixtures (always 1 wt% total) of multi-wall carbon nanotubes (MWNTs) and single-layer graphene (SLG) were mix...

The filler/matrix interface in fiber-reinforced polymer composites is critical in controlling load transfer from the matrix to the fiber, failure mechanisms, and degradation. It is not clear, however, how the mechanisms of load transfer in traditional composites apply to nanofiber-filled polymers. This paper is focused on understanding the reinforcement mechanisms in multiwalled carbon nanotube...
