In the field of nanotechnology, Multi-walled Carbon Nanotubes (MWCNTs) have gained significant attention due to their unique structural properties and potential applications in various industries. One of the key challenges in utilizing MWCNTs is their poor dispersion stability in aqueous solutions. However, recent research has shown that the addition of polymeric dispersants can greatly enhance the dispersion stability of MWCNT waterborne dispersions.
Polymeric dispersants are molecules that can interact with both the MWCNTs and the water molecules to create a stable dispersion. These dispersants form a protective layer around the MWCNTs, preventing them from aggregating and settling out of the solution. This enhanced dispersion stability allows for better control over the properties of the MWCNT dispersions, making them more suitable for a wide range of applications.

Application in coatings and composites of Multi-walled Carbon Nanotube Waterborne Dispersions with Polymeric Dispersant
The enhanced dispersion stability of MWCNT waterborne dispersions with polymeric dispersants opens up a plethora of new possibilities for their use in coatings and composites. Coatings formulated with these dispersions exhibit improved mechanical, thermal, and electrical properties due to the presence of well-dispersed MWCNTs.
In the field of composites, MWCNT waterborne dispersions with polymeric dispersants can be incorporated into various matrices to enhance their strength, conductivity, and overall performance. These composites find applications in and electronics industries where lightweight and high-performance materials are in demand.
Moreover, the use of polymeric dispersants in MWCNT waterborne dispersions allows for better adhesion between the MWCNTs and the matrix material, resulting in improved mechanical properties and durability of the final product.
In coatings, MWCNT waterborne dispersions can enhance the hardness, scratch resistance, and corrosion protection of the coating. The high aspect ratio and inherent strength of MWCNTs make them ideal reinforcement materials for coatings, creating a barrier that increases durability and longevity.
Scalability and commercialization of Multi-walled Carbon Nanotube Waterborne Dispersions with Polymeric Dispersant
Researchers have been working on developing waterborne dispersions of MWCNTs with polymeric dispersants. These dispersions not only improve the stability of MWCNTs in aqueous solutions but also make them more suitable for large-scale production and commercial use.
Several studies have demonstrated the effectiveness of polymeric dispersants in stabilizing MWCNT dispersions and enhancing their dispersibility in water. For example, a study showed that the use of a polymeric dispersant significantly improved the dispersion of MWCNTs in water, leading to better compatibility with various polymer matrices and enhanced mechanical properties of resulting composites. This finding suggests that polymeric dispersants can play a crucial role in facilitating the incorporation of MWCNTs into commercial products.
Furthermore, the scalability of MWCNT waterborne dispersions with polymeric dispersants has been demonstrated in several studies. For instance, a study reported on the successful large-scale production of MWCNT dispersions using a combination of polymeric dispersants and high shear mixing techniques. This approach not only enabled the production of stable MWCNT dispersions in large quantities but also maintained the structural integrity and properties of the nanotubes, making them suitable for industrial applications.
