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.
通过比较单根纳米纤维的实验测量值和计算机模拟值，在纤维素纳米纤维的表面上检测到了原子级的凹痕结构。这些凹痕部分至少占分散纳米纤维总长度的 30-40%，而较深的凹痕则导致纳米纤维的弯曲和断裂。
