Polymer Nanocomposites with Copper Nanowire and Carbon Nanotubes: Hybrid Materials exhibiting Low Electrical Percolation Thresholds, High Electrical Conductivity,and High EMI Shielding

摘要

Hybrid nanocomposites of multi-walled carbon nanotubes and copper nanowires in polystyrene were prepared by miscible mixing and precipitation method. Extremely low electrical percolation thresholds in MWNT/PS and CuNW/PS nanocomposites were observed at 0.052 and 0.67 vol. percent, respectively. Electrically conductive polymer nanocomposites exhibiting high Electromagnetic Interference (EMI) Shielding effectiveness are reported.
