Selecting uDIAMOND® materials

ndmaterials.png

Selecting the correct uDiamond® material(s) will depend on your application, and we always recommend contacting us to discuss your requirements.

The primary concern is usually to consider the appropriate morphology to achieve the best possible dispersion characteristics within your chosen application. Generally the most effective and economic method is to apply a uDiamond® liquid dispersion into the parent material / media, provided that there is a compatible solvent system to facilitate this. Currently uDiamond® liquid dispersions are available as stock materials in aqueous, Di-Ethylene Glycol, NMP and NEP solvents as well as GBL by special order, with several further solvent systems in development or available for custom applications.

Where there is no compatible solvent system, uDiamond® nanodiamond powders can be used, for example in many thermoplastic and thermoset applications. Carbodeon has developed a number of techniques to aid our customers in dispersion these powders into their own materials.

The other key parameter in nanodiamond material selection is the choice of surface chemistry. This will influence a number of factors including the pH stability of any aqueos dispersions used, the agglomeration thersholds of the materials in the presence of certain other media and the extent and method of interface/ interaction between nanodiamond material and parent material or other fillers. In electrochemical applications such as electroplating, the zeta potential of the nanodiamond material is also a factor.

Considerations at the start of any nanodiamond project include determining what material properties should be modified or obtained, how such properties shall be measured, and at what point in the material or product manufacture to introduce the nanodiamond. Considerations of parent material, processing and supply chain shall all be relevant factors.
