Because carbon nanotubes have a similar structure to polymer materials (epoxy resin, polystyrene, polymethyl methacrylate, polyacetylene, nylon and polyurethane, etc.), it is easy to form an ideal interfacial bonding force when mixed, resulting in improved performance. The composite material exhibits excellent strength, wear resistance, electrical conductivity, antistatic properties and other properties that the polymer itself does not have.
1. The acidified carbon nanotubes were compounded with high-density polyethylene (HDPE), and the oriented carbon nanotubes/HDPE composites were prepared by mechanical blending method, which improved the yield strength and tensile strength of the composites. modulus.
2. The carbon nanotube/polytetrafluoroethylene composite material prepared by the customer has a reduced coefficient of friction and improved wear resistance.
3. A company uses carbon nanotubes to reinforced polyurethane composite materials, with a strength/weight ratio of more than 50%, to manufacture larger, stronger and lighter wind turbine blades, so that the power generation of wind turbines can reach more than 1.5MW.
4. Poly(3-octylthiophene)/carbon nanotube composites, the electrical conductivity is improved by 5 orders of magnitude.
5. Adding 8.5wt% single-walled carbon nanotubes to polystyrene-isoprene reduces the resistivity by 10 orders of magnitude.
6. Adding 2-3% of multi-walled carbon nanotubes to the plastic can greatly improve the electrical conductivity; dispersing carbon nanotubes in an epoxy resin, a small amount of addition can produce higher electrical conductivity. Adding 10% carbon nanotubes to engineering plastics such as polycarbonate and polyamide, the conductivity is much higher than other conductive fillers of the same kind. Based on this, the demand for carbon nanotubes in the plastics industry is increasing day by day. china professional carbon nanotube supplier –www.hwnanomaterial.com.
