Abstract:
1. A method for measuring the water content of a fluid or paste comprising multi-walled carbon nanotube agglomerates, dispersant and polymeric binder, the method comprising the steps: selecting the fluid or paste comprising the multi-walled carbon nanotube agglomerates, the dispersant and the polymeric binders and further comprising a first solvent, wherein the multi-walled carbon nanotube agglomerates, the dispersant and the polymeric binder of the fluid or paste are dispersed in the first solvent; adding a second solvent to the fluid or paste such that the second solvent is more than about 25% by volume or weight ratio of the total solvent mixture of the first solvent and the second solvent and wherein the multi-walled carbon nanotube agglomerates do not disperse in the total solvent mixture and the second solvent is miscible with the first solvent; precipitating the multi-walled carbon nanotube agglomerates from the total solvent mixture, thereby leaving a supernatant; taking a sample of the supernatant; and measuring the water content of the sample.
