Due to their thermal conductivity, mechanical and electrical properties, carbon nanotubes (CNTs) are potentially useful in a wide variety of applications such as composite materials, electronic sensors, energy storage and filtration. CNTs form bundle-like structures with complex morphologies and strong van de Waals interactions. This results in poor dispersion of CNTs in different mediums, which is a key challenge in practical applications.
To facilitate the ease of use of CNTs in practical end applications, the company is seeking expertise and/or technologies to create single-walled CNTs (SWCNTs) dispersions in water.
The SWCNT dispersion can be obtained via chemical methods (e.g. formulation of surfactants), physical methods (e.g. ultrasonication), or their combinations.
The desired SWCNT dispersion should:
The critical functional properties to be evaluated include:
