The dispersibility and wettability of the powder can be possible to measure by low-field NMR. The characteristic is being able to measure with good reproducibility in a short time without diluting. As a concrete measurement example of dispersibility, we prepared 30 wt% carbon black dispersed to NMP and PVDF under the different the dispersion condition. It became clearly the dispersibility was changed after just mixture and one day later. In addition, an example was shown difference of graphene’s surface modify time in which the wettability was also compared. It showed to easily convert into numerals wettability changing.
