Solvent levels, carbon nanotubes

When the carbon nanombe is alone, the carbon nanotube HOMO-LUMO energy levels increased by about 0.5 eV when changing from vacuum to water solvent conditions. 

When 1 wt% of CNTs were added to the rubber the stress level for the nanocomposite material increased from 0.2839 to 0.56413 MPa. At 10 wt% of CNTs the stress value obtained reached 2.55 MPa which is nine times that of pure NR." Nanocomposites of NR reinforced with SiC nanoparticles and single-walled carbon nanotubes were synthesized and processed using toluene as the solvent." Both types of nanocomposite showed an increase in initial modulus with increasing filler content, with a maximum initial modulus at 1.5% filler content. The tangent modulus at 200% strain further confirms the enhancement of reinforcement by the nanofillers at 1.5% content.
