纤维素纳米晶的掺入能够增加胶原基复合膜的表面粗糙度,其胶原膜截面具有更明显的仿生层状结构, 胶原基复合膜的拉伸强度和弹性模量具有较大提升, 且随着掺入量的增加而显著增强。
The incorporation of cellulose nanocrystals can increase the surface roughness of the collagen matrix composite film, and the cross section of the collagen film has a more obvious bionic layered structure. The tensile strength and elastic modulus of the collagen matrix composite film are greatly improved, and are significantly enhanced with the increase of the incorporation amount.
