Electrical Percolation Effect on Electromechanical Behavior of CNT Nanocomposites
Yves Ngabonziza, Jackie Li
Electrical resistance responses of multi-walled carbon nanotubes (MWCNT) reinforced polypropylene (PP) nanocomposites under mechanical tensile loading are studied in this paper. A standard tensile test was conducted while the electrical resistance was measured using 2-probe method. From our previous works on the CNT/PP nanocomposites, the percolation threshold of electrical conductivity is around 3.8 wt% of CNT. The influence of this percolation threshold on the electrical resistance upon mechanical loading was investigated. The results will be discussed and compared. Full Text
