Applications of Multi Walled Carbon Nanotubes, Purity: >95%, Outside Diameter: 30-80 nm

• Electrically Conductive and Antistatic Composites: MWCNTs can be incorporated into thermoplastics, thermosetting resins, and elastomers to establish electrically conductive networks. Potential applications include antistatic components, electrostatic discharge (ESD) protective materials, and conductive polymer compounds. The resulting conductivity depends on nanotube loading, dispersion quality, and the processing conditions used to form the conductive network.
• Mechanical Reinforcement: MWCNTs are investigated as reinforcing additives in epoxy resins and other polymer composites. With suitable dispersion and effective bonding at the nanotube–matrix interface, they can contribute to improved stiffness, strength, and resistance to deformation. These characteristics support the development of multifunctional composites that combine mechanical reinforcement with electrical functionality.
• Electromagnetic Interference Shielding: MWCNT-filled polymers and coatings can be used to develop electromagnetic interference (EMI) shielding materials. Their interconnected conductive networks contribute to electromagnetic wave attenuation through absorption and reflection. Applications include shielding layers and polymer components for electronic equipment, with shielding effectiveness governed by filler concentration, network connectivity, material thickness, and operating frequency.
• Battery Electrode Conductive Additives: MWCNTs can serve as conductive additives in lithium-ion battery electrodes, helping establish electronic pathways between active material particles. Properly dispersed nanotubes can support electron transport and improve the utilization of electrode materials, particularly in formulations where electrical conductivity limits performance. Electrode suitability depends on active material chemistry, impurity levels, binder compatibility, and slurry processing.
• Thermal Management Composites: MWCNTs are explored as additives for improving heat transport in polymer-based materials. When appropriately distributed, they can contribute to thermally conductive pathways within resins and hybrid filler systems. Potential applications include heat-spreading composites and multifunctional encapsulation materials, with performance strongly influenced by nanotube–matrix interfaces and filler network structure.
• Strain and Pressure Sensors: MWCNT–elastomer composites can function as piezoresistive sensing materials, exhibiting changes in electrical resistance when stretched or compressed. This behavior supports applications in flexible strain sensors, pressure-sensitive components, and wearable motion-monitoring devices. Sensitivity, repeatability, and operating range depend on nanotube dimensions, concentration, dispersion, and sensor design.
• Electrically Heated Coatings and Films: MWCNTs can be incorporated into conductive coatings and polymer films that generate heat through the Joule effect when an electrical voltage is applied. These systems are investigated for resistive heating elements, heated surfaces, and electrothermal composite components. Heating uniformity and power requirements depend on electrical resistance, nanotube distribution, electrode configuration, and the thermal limits of the surrounding polymer.
