| Outline of Final Research Achievements |
It has been demonstrated that the agglomerates of a carbon nanotube (CNT) or carbon black (CB) suspended in organic solvents can be dispersed satisfactorily by the barrier discharge generating under ac high voltage and the effect of electric field without particular chemical agents or additives. These new electrical methods are named as Discharge dispersion method (DDM) and Field dispersion method (FDM), respectively. The superior dispersibility of nanoparticles is obtained by the combination of DDM and FDM. On the other hand, it has been revealed that the mechanical and electrical properties of nanocomposite materials can be improved by using dispersed CNT or CB particles as filler. Two types of the nanocomposite (epoxy resin composite and elastomer composite) with a different particle concentration are fabricated to examine their electrical and mechanical properties. These properties reveal a nonlinear variation by adding a slight amount of nanoparticles in the range 0.01to 0.1 wt%.
