The Effect of Triton® X-100 on CNT/PP Composite’s Electrical Conductivity

Abstract

TCNT(Triton® X-100 pre-treated carbon nanotubes)/ PP (Polypropylene) composite has been successfully prepared and charactered by SEM, electrical tests. It was found that the best usage of Triton X-100 (P-octyl polyethylene glycol phenyl ether) was 80 wt% based on the CNTs. The results showed that the TCNTs could effectively improve the composites’ electrical conductivity over pristine CNTs. The mechanisms for the results have been discussed.

“…Compared with a dry contact between MGNS particles, the contact resistance will be reduced even if the resistivity of the surfactant is much higher than MGNS because the surfactant adds a conduction path. Although the electrical resistivity of Triton X100 has not been characterized here, there are a few reports of electrical conductivity enhancement in carbon nanotube composite materials [42] and liquid solutions [43]. An alternative explanation could be, as the deposited ink dried, water molecules that solvated the poly(oxyethylene) chains began to vaporize, causing the polymer chains to constrict and draw particles together, forming more particle-particle contacts and, thus, lowering film resistivity.…”
