The Benefits of SWCNT for Producing Conductive Plastic Composites

New electrically conductive SWCNT-polyethylene composites with ultralow percolation thresholds have been developed. The melt mixing of different grades of polyethylene with SWCNTs was performed as a function of melt flow index (MFI) of polyethylene, achieving electrical resistivity in the range 10 4 –10 8 ohm*cm at 0.05–0.1 wt% of SWCNTs in compressionmoulded samples. Such low percolation thresholds show that TUBALLTM SWCNTs can achieve perfect dispersability using a melt mixing approach, which makes these SWCNTs very promising for conductive polymers applications.
