Biomaterials have attracted worldwide attention due to the concerns regarding health and the environment. Silk, a natural protein produced by several species of insects, has been examined as a potential material for applications in many biotechnological and biomedical fields. However, regenerated silk fibroin has poor ductility and mechanical properties. Therefore, in this study, silk fibroin-cellulose composite films were prepared in an aqueous system to increase the ductility of regenerated silk fibroin. The morphology of the silk fibroin-cellulose composite film was observed by field emission scanning electron microscopy. The structure of the silk fibroin-cellulose composite films was examined by Fourier transform-infrared spectroscopy. The flexibility was analyzed using a bending test.
由于对健康和环境的关注，生物材料已引起全球关注。丝绸是几种昆虫产生的天然蛋白质，已被作为一种潜在材料用于许多生物技术和生物医学领域。然而，再生丝素蛋白的延展性和机械性能较差。因此，在本研究中，在水体系中制备了丝素蛋白-纤维素复合膜，以提高再生丝素蛋白的延展性。通过场发射扫描电子显微镜观察丝素蛋白-纤维素复合膜的形态。通过傅里叶变换红外光谱法检测丝素蛋白-纤维素复合膜的结构。使用弯曲试验分析柔韧性。
