Embodiment 1
[0026] The high-density polyethylene resin is crushed and then sieved to obtain particles with a particle size of 50-200 microns for use. Disperse 0.01 g of carbon nanotubes in 10 g of absolute ethanol and form a stable suspension after ultrasonication for 2 hours. Add 10 grams of high-density polyethylene particles to the suspension, and continue ultrasonic oscillation for 60 minutes. When the surface of the polymer particles is completely covered by carbon nanotubes, heat and evaporate to remove the solvent, and form carbon nanotube-high-density polyethylene particles Pour the mixed system into a mold, heat it to 180°C until the high-density polyethylene melts; apply a pressure of 10 MPa and keep it for 5 minutes, so that the high-density polyethylene resin flows and forms an integration with the carbon nanotube network; cool to room temperature , demoulding, and a carbon nanotube / high-density polyethylene composite material was obtained; its volume resistivity at room tempe...
Embodiment 2
[0028] Select polypropylene particles with a particle size between 50 and 200 microns for use; disperse 0.5 g of carbon nanotubes in 30 g of absolute ethanol, and form a stable suspension after ultrasonic oscillation for 2 hours. Add 10 grams of high-density polyethylene particles into the suspension, and continue ultrasonic oscillation for 60 minutes. When the surface of the polymer particles is completely covered by carbon nanotubes, heat and evaporate to remove the solvent to form a uniform carbon nanotube-polypropylene particle mixture. system; pour the mixed system into a mold, heat to 200 ° C until the polypropylene melts; apply a pressure of 10 MPa and keep it for 5 minutes, so that the polypropylene resin flows and forms an integration with the carbon nanotube network; cool to room temperature, demold, and make A carbon nanotube / polypropylene composite material was obtained; its volume resistivity at room temperature was 7.35×10 2 ohm cm.
