Effect of multi walled carbon nanotubes (MWNTs)/Silver Powder Content and additives on Electrical Conductivity of MWNT/Ag powder/epoxy three-phase composites. |
초록 |
The electrical conductivity of oxidized multi walled carbon nanotubes (MWNTs)/Ag powder/epoxy three-phase composites is investigated. In this study the electrical conductivity of two types chemical functionalized (acidic and basic conditions) multi-walled carbon nanotubes is evaluatedThe electrical conductivity of MWNTs oxidized by mixture of H2O2/NH4OH solutions is higher than HNO3/H2SO4 solutions.The electrical conductivity of epoxy composites filled with the oxidized MWNTs is measured by a dielectric analyzer and analyzed using percolation theory.Effect of surfactants and silane coupling agents on electrical properties also measured. Small amount of non-ionic surfactant and glycidoxypropyltrimethoxy silane enhance the conductivity of composites.electrical properties of the composite with different weight percentages of nanotubes have been investigated. |
