When venturing into the realm of advanced materials, understanding the technical specifications of products is paramount to ensuring successful application and optimal performance. For carbon nanotube (CNT) powders, several key parameters dictate their suitability for specific industrial uses. Ningbo Inno Pharmchem Co., Ltd. is dedicated to providing clarity on these specifications, empowering our clients to make informed decisions when they purchase carbon nanotubes.

One of the most critical specifications is purity. High-purity carbon nanotube powders, typically above 95% or even 99%, are essential for applications demanding precise electrical or thermal conductivity, such as in advanced electronics or high-performance batteries. Impurities, such as residual catalysts or amorphous carbon, can significantly degrade these properties. When considering cost-effective carbon nanotube additives, it's important to balance price with the required purity level for your application.

The average diameter and length of the nanotubes are also crucial. For multi-walled carbon nanotubes (MWCNTs), diameters often range from 15-30 nm, while lengths can vary from 5-15 μm or even up to 50 μm. Smaller diameters and longer lengths generally contribute to better mechanical reinforcement and electrical conductivity due to a higher aspect ratio. This is particularly relevant for applications like conductive coatings where uniform dispersion and effective network formation are key.

Specific Surface Area (BET) is another vital parameter, typically measured in m²/g. A higher BET value indicates a greater surface area available for interaction with other materials. For CNTs, BET values often range from 90-170 m²/g, and can be significantly higher for single-walled CNTs. This large surface area is instrumental in applications where surface interactions are critical, such as in catalysis or as reinforcement in polymer composites.

Ash content and moisture content are also important indicators of product quality and processing suitability. Low ash content (e.g., ≤ 0.5%) signifies minimal inorganic impurities, while low moisture content ensures stability and ease of handling. These factors are particularly important when looking to enhance material conductivity with MWCNT for sensitive applications.

When selecting carbon nanotube powders, consider the specific requirements of your application. For instance, if you are developing advanced batteries, seeking high purity carbon nanotubes with specific diameter and length distributions will be essential. For industrial coatings, factors like dispersibility and compatibility with the binder system will be equally important. Ningbo Inno Pharmchem Co., Ltd. offers a range of high-quality carbon nanotube powders, and our team is available to assist you in selecting the optimal product for your needs.

In summary, understanding specifications like purity, diameter, length, BET surface area, ash, and moisture content is key to effectively utilizing carbon nanotube powders. By prioritizing these parameters, industries can unlock the full potential of these advanced materials, from creating superior conductive coatings to developing next-generation energy storage solutions.
