通过比较实验测量和计算机模拟的单个纳米纤维的宽度，检测到了纤维素纳米纤维表面的原子尺度凹陷结构。这些凹陷部分至少占分散纳米纤维总长度的30%-40%，深凹陷导致纳米纤维的扭曲和断裂。
Atomic-scale dent structures on the surfaces of cellulose nanofibers were detected by comparing the experimentally measured and computer-simulated widths of single nanofibers. These dent parts constituted at least 30–40% of the total length of the dispersed nanofibers, and deep dents induced the kinking and fragmentation of nanofibers.
