The X-diffraction spectrum show that the crystallinity of the silk fibroin membrane increases after surface treatment with phosphoric acid.
衍射表明丝素膜用磷酸处理后，增加了丝素膜的结晶度。
Because the fiber is of chemical inertion, low surface energy, lack of polar groups, and highly symmetric methylene structure, the fiber has a high degree of crystallinity and orientation.
这是由于纤维在化学上不活泼，表面能低，表面缺乏极性基团，且是高度对称的亚甲基结构，使得纤维具有很高的结晶度和取向度。
The surface of flax fiber became rough and crystallinity decreased while increasing oxidized degree of flax fiber. The structure and properties of the proteinic oxidized flax fiber were studied.
