与纯胶原膜相比，不同质量比的胶原基纤维素纳米晶复合膜的饱和含水率和透光性能没有显著区别； 随着纤维素纳米晶掺入量的增加，胶原基复合膜的体外降解速率显著加快，其中7 wt% CNCs 的体外降解速率与COL 相似，能够满足角膜修复的需要。

Compared with pure collagen films, the saturated water content and light transmittance of collagen based cellulose nanocrystalline composite films with different mass ratios were not significantly different. With the increase of cellulose nanocrystalline incorporation, the in vitro degradation rate of collagen matrix composite membrane was significantly accelerated, and the in vitro degradation rate of 7 wt% CNCs was similar to that of COL, which could meet the needs of corneal repair.
