Development of Green Nano-Fibrillated Fibroin–Sericin Composite Films
Source abstract
Abstract
Regenerated silk fibroin (SF) nanofibers are known for their brittleness, which poses challenges for practical applications. Moreover, the complete removal of sericin (SS) adversely affects the mechanical properties of SF. This study presents an innovative, green, one-step method for extracting nano-fibrillated SF using only water, through a combination of autoclaving and grinding treatments. Silk fibers (SF/SS) were autoclaved for varying durations to retain different amounts of SS and enhance mechanical performance. A series of SF/SS samples with different degumming times was prepared to assess the influence of SS content before and after film formation. A set of fibroin–sericin-based nano-fibrillated (FNF/SS) composite films with improved mechanical properties was developed. Controlled SS content significantly enhanced the mechanical performance of SF.
