摘要：

Highly ordered cellulose nanofibers/silk fibroin nanohybrid (CSN) honeycomb materials with multi-scale hierarchical architectures are successfully prepared from CSN hydrogel precursors using unidirectional freeze-drying technique. Cellulose nanofibers have an outstanding highly ordered honeycomb structure-directing function in composite hydrogel. However, silk fibroin does not have such function. Therefore, the properties of the CSN sponges can be effectively adjusted by simple changing the ratio of cellulose nanofibers to silk fibroin. When the content of silk fibroin reaches 50%, the CSN-50 sponge exhibits a nearly perfect highly ordered honeycomb structure with multi-scale hierarchical architectures. And the Brunauer-Emmett-Teller specific surface area is about 120 m(2) g(-1).
