| 摘 要： | 以溶胶-凝胶法制备纳米TiO2改性丝素复合膜,用原子力显微镜(AFM)观察,发现纳米TiO2均匀地分散在丝素中,粒子之间有明显的连续相,没有出现明显的相分离现象,其粒径约为80 nm。改性后的丝素膜,其上染率和色牢度均比纯丝素膜大大提高。

| Abstract: | With the sol-gel method,the regenerated silk fibroin(SF) /nano-TiO_2 composite films were synthesized.The experimental results revealed that the nano-TiO_2 particles were well dispersed in the regenerated silk fibroin.There were obvious continuous phases between the particles and no obvious separation phenomenon appeared.The diameter of nano-TiO_2 particles was about(80 nm) by AFM.The dye uptake and sunlight fastness of the modified silk fibroin composite films were enhanced remarkably. |
