Dynamic percolation curves of PC/MWCNT composites (MWCNT volume fraction 1.19%) annealed at under various electric fields. The inset shows the variation in percolation time with electric field.
Arrhenius plots of vs the inverse of annealing temperature for PC/MWCNT composites (MWCNT volume fraction 1.19%) under various electric fields. The left inset shows a series of dynamic percolation curves (500 V/cm) from which the relationship between vs annealing temperature can be obtained. The right inset shows the relationship between the activation energy of dynamic percolation and the applied electric field.
Dependence of on the applied electric field. The two insets show the relationship between MWCNT volume fraction vs under 1 and 1000 V/cm, respectively.
Time dependence of volume resistivity for PC/MWCNT composites (MWCNT volume fraction 0.59%) measured at during the switch of the electric field between 500 and 1 V/cm. The four inserted circular patterns are the schematic structure of the aligned MWCNTs under corresponding electric field.
