What is carbon nanotube PEI
Carbon nanotubes (PEI) are compounded with carbon nanotubes (CNTS) and polyetherimide (PEI) base materials. Polyetherimide (PEI) is a high-performance engineering plastic with excellent heat resistance, mechanical strength and chemical stability. Carbon nanotubes are nanotube-like structures composed of carbon atoms with excellent electrical conductivity, mechanics, and thermal properties. The addition of carbon nanotubes to polyetherimide can improve the conductivity, mechanical properties and thermal properties of the material. Carbon nanotubes have high electrical conductivity, so they can improve the conductivity of polyetherimide. In addition, carbon nanotubes can also enhance the mechanical strength and stiffness of materials and improve their thermal conductivity. Carbon nanotube PEI composites have a wide range of application prospects in electronic devices, conductive coatings, sensors, composite structural materials and other fields. By adding carbon nanotubes to PEI, the material can be given conductive properties, making it suitable for applications in the field of electronics. In addition, carbon nanotube PEI composites also have excellent mechanical properties and thermal conductivity properties, which can be used to prepare high-performance structural materials. The preparation and application of carbon nanotube PEI composites need to consider the addition amount and dispersion of carbon nanotubes, as well as the safety and environmental impact of the materials. When using, it is necessary to follow the relevant operation and handling specifications to ensure personal safety and environmental health.
What is carbon nanotube pei.
Carbon nanotube PEI is a material that is incorporated into the substrate with conductive substances such as carbon nanotubes to increase its conductivity and achieve antistatic function. Its main features are:
It has good high temperature resistance and can be used for a long time in an environment below 220 degrees Celsius.
Good mechanical strength and wear resistance, even under high load conditions, can maintain its original performance.
High chemical resistance, can be processed by injection molding, thermoforming, extrusion and other methods, with a certain plasticity and moldability.
It has good anti-static properties, which can effectively eliminate static electricity and will not affect other properties of the material.
How are carbon nanotubes PEI conductive?
Carbon nanotube PEI has good conductivity. PEI carbon nanotubes are made of polyetherimide PEI resin as the base material, modified by adding conductive fillers (carbon fiber, carbon black, carbon nanotubes) and other additives, and their surface resistivity is 10 to the 2-5th power ohm. Carbon nanotube PEI also has the characteristics of high temperature resistance, natural flame retardant, low creep, dimensional stability, high strength modulus, long-term heat resistance, chemical resistance, food grade, etc., and is suitable for the manufacture of various types of high-temperature wafer carrier frames, wafer rods, conveyor racks, aircraft parts and radar absorbing materials, first-class products, mechanical turbine valve bearing gears, medical appliances, extruded plates and bars, etc.
