Rapid detection method for fibrillation degree of nanocellulose

The invention belongs to the technical field of nanocellulose, and discloses a rapid detection method for the fibrillation degree of nanocellulose. The rapid detection method comprises the following steps: 1) preparing a suspension from known nano cellulose by using water as a standard sample; then, preparing to-be-detected nanocellulose into a to-be-detected suspension by adopting water, using the to-be-detected suspension as a to-be-detected sample, and the concentration of the to-be-detected sample being the same as that of the standard sample; 2) respectively filling a sample to be detected and a standard sample into two semitransparent or transparent containers with the same volume, placing the container in a centrifugal device for centrifugal sedimentation, after centrifugation, collecting the standard sample and the supernatant of the to-be-detected sample in a transparent container, comparing the time required for secondary sedimentation of the to-be-detected sample and the standard sample, and under
