Product Overview

Our SO3H-Functionalized Multiwalled Carbon Nanotubes (MWCNTs) are a pinnacle of nanotechnology engineering, designed to deliver unmatched performance in catalysis, proton exchange membranes, and composite materials. By introducing sulfonic acid groups (-SO3H) on the surface, these MWCNTs exhibit increased hydrophilicity, chemical reactivity, and ionic conductivity, making them ideal for a wide range of advanced applications.

Key factor

  • Enhanced Chemical Reactivity: The presence of sulfonic acid groups significantly increases the surface reactivity, enabling efficient catalytic processes and chemical modifications.
  • Improved Dispersion in Water: SO3H functionalization enhances the hydrophilicity of MWCNTs, ensuring better dispersion in aqueous solutions and polymer matrices.
  • Increased Ionic Conductivity: Ideal for applications requiring high ionic conductivity, such as fuel cell membranes and sensors.
  • Versatile Application Potential: Suitable for use in catalysis, energy storage, water treatment, and as a reinforcement agent in polymer composites.

Applications

  • Catalysis: Acts as a solid acid catalyst for esterification, transesterification, and other acid-catalyzed reactions.
  • Energy Storage: Enhances the performance of electrodes in batteries and supercapacitors.
  • Polymer Composites: Improves mechanical strength, thermal stability, and ionic conductivity of polymer matrices.
  • Water Treatment: Utilized in adsorption and filtration processes for the removal of pollutants.

Advantages

  • Enhanced Chemical Reactivity: The introduction of sulfonic acid groups (-SO3H) on the carbon nanotubes' surface significantly increases their chemical reactivity, making them highly effective as catalysts in various chemical reactions.
  • Improved Dispersion: The hydrophilic nature of the SO3H groups improves the dispersion of these carbon nanotubes in water and other polar solvents, facilitating easier integration into different matrices and solutions.
  • Increased Ionic Conductivity: The SO3H functionalization enhances the ionic conductivity of the carbon nanotubes, making them suitable for use in energy storage devices, fuel cells, and other applications requiring efficient ion transport.
