The evaluation of critical phenomena related to percolative networks of carbon nanotubes in high density polyethylene matrix

In this simulation, the electrical conductivity (σcom) of high density polyethylene-single walled carbon nanotube (HDPE-SWCNT) nano-composite has been simulated with finite element method. The values of σcom obey a percolation power law that depends on percolation threshold of inclusions   c  and critical exponent (t). Near c , there was a drastically sudden increasing in electrical conductivity of nano-composite. We calculated c and t for HDPE-SWCNT nano-composite with COMSOL MULTIPHYSICS software. The results were in good accordance with experimental ones
