Conductive Carbon Black Nanopowder Water Dispersion ( C, 150 nm, 35wt% )

Conductive Carbon Black Nanopowder Water Dispersion (C, 150 nm, 35wt%) is a colloidal solution that contains carbon black nanoparticles suspended in water. Here’s an overview of its key features and applications:

1. Key Features:
   • Conductive Carbon Black (C): The dispersion contains carbon black, a form of carbon produced by incomplete combustion of hydrocarbons. It is widely used for its excellent conductivity and reinforcement properties. Carbon black particles in this dispersion are highly conductive, making it valuable for electronic and energy-related applications.
   • Nanoparticles: The carbon black particles in this dispersion have an average size of 150 nanometers (nm). While larger than many other types of nanoparticles, this size still provides significant surface area, which enhances the conductivity and interaction potential in various applications.
   • Water Dispersion: The carbon black particles are suspended evenly in water, forming a stable colloidal solution. Stabilizing agents are typically used to prevent aggregation or settling of the nanoparticles over time.
   • Concentration: The dispersion has a 35 wt% (weight percent) concentration, meaning it contains 35 grams of carbon black nanoparticles per 100 grams of solution.
2. Properties:
   • Conductivity: Carbon black is highly conductive, and its nanoparticles are ideal for applications requiring electrical conductivity, such as in conductive coatings and inks. The high concentration of carbon black in this dispersion (35 wt%) increases its conductivity significantly.
   • Large Particle Size: With 150 nm particles, the carbon black nanoparticles provide a balance between surface area and stability. The larger size compared to typical carbon nanotubes or graphene nanoparticles may offer better dispersion stability, especially in aqueous solutions.
   • Surface Area and Reinforcement: Carbon black nanoparticles possess a high surface area that enhances their reinforcement properties in various composite materials, improving strength, flexibility, and durability.
   • Stability: The dispersion is typically stabilized to ensure uniform distribution of carbon black particles in the solution, preventing agglomeration or settling over time.
3. Applications:
   • Conductive Coatings: Due to its excellent conductivity, this carbon black dispersion is used in the production of conductive coatings for electronic devices, antistatic coatings, and electromagnetic shielding.
   • Electronics and Inks: It is widely used in the manufacturing of conductive inks for printed electronics, RFID tags, and sensors, as well as for coatings in the electronics industry.
   • Batteries and Supercapacitors: Carbon black is used as a conductive filler in energy storage devices, including batteries and supercapacitors, to enhance charge and discharge performance.
   • Rubber and Plastics: Carbon black is commonly used as a reinforcing agent in rubber and plastics, improving the mechanical properties, such as strength, wear resistance, and heat dissipation. This dispersion can be incorporated into composite materials to improve these properties.
   • Antistatic Applications: This dispersion can be used in applications that require antistatic properties, such as in the production of packaging materials for sensitive electronic components and devices.
4. Handling and Safety:
   • Toxicity: Carbon black is generally considered to be of low toxicity; however, inhalation of fine carbon black particles may pose health risks. As with all nanoparticles, it is important to avoid inhalation, ingestion, or skin contact. Appropriate safety measures should be taken when handling the dispersion.
   • Storage: Store the dispersion in a cool, dry environment, away from heat or direct sunlight, to maintain its stability and prevent the nanoparticles from aggregating.
   • Precautions: Wear appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats when handling the dispersion. Ensure work is carried out in a well-ventilated area or under a fume hood to minimize exposure to airborne particles.

With a concentration of 35 wt%, this carbon black dispersion offers a highly concentrated solution, making it especially useful in applications requiring strong conductivity, such as in conductive coatings, inks, energy storage devices and composites.
