Under dry conditions, only particles that directly filled the pots were observed, whereas under the wet conditions, particles mixed with water filled the pots. Accordingly, the wet grinding of the CNTs produced long fiber shapes. During the grinding process, the impact forces of the milling balls are different between the dry and wet conditions.
