ABSTRACT = {Silk fibroin (SF) with renewability, biocompatibility and biodegradability shows potential
application in various fields including biomedicine, tissue engineering, and wearable electronic
devices. Herein, SF is used to exert effective reinforcement of polyvinyl alcohol (PVA) composite
film to further improve its practicability. As such, PVA/SF composite films were prepared for the
first time using a facile approach. The films were characterized to investigate possible interaction
of PVA with SF. Meanwhile, systematic investigations have also been completed to explore the
influences of PVA/SF mass ratio on the mechanical properties (tensile strength, elongation at
break), biodegradability and biocompatibility, the morphology, crystallinity, chemical structure
and thermostability. It is interesting to find that SF in the PVA/SF can remarkedly exert
reinforcement efficacy and improve the mechanical properties, biodegradability and
biocompatibility. Due to the reinforcement efficacy of SF, the tensile strength and elongation at
break of the PVA/SF material are higher than that of neat PVA material by about 28% and
286%, respectively. Moreover, the materials are biodegradable and biocompatible. The simple
and maneuverable approach as well as high-performance properties possessed by the materials
will further broaden their practical application.},
