Résumé : |
A novel collagen-soy protein isolate (SPI) film formed via self-assembly was developed. This research investigated the structure and application properties of the collagen-SPI self-assembled film and the blend film. FTIR and XRD evaluation of structural properties indicated that the self-assembly method could effectively enhance the compatibility between collagen and SPI. The collagen-SPI self-assembled film presented a compact, smooth and continuous microstructure. The tensile strength (Ts) and elongation at break (EAB) values of the collagen-SPI self-assembled films (Ts : 13.991 ±0.53 MPa, EAB : 84.57 ± 6.21%) were nearly twice those of the blend films. The water vapour permeability (WVP) values of the collagen-SPI self-assembled film were more than 2000 g•m-2.24h. The maximum decomposition peak of collagen-SPI self-assembled films was located at 313.2°C. The collagen-SPI self-assembled films could achieve swelling equilibrium quickly within 2 hours, and the structural integrity of the film was maintained for 24 hours. The collagen-SPI self-assembled film had excellent ultraviolet shielding and visible light transmission qualities. The collagen-SPI self-assembled film had better mechanical properties, optical properties, thermal stability and water resistance properties as opposed to blend film. As a clean and feasible method, the self-assembly method could improve the functional properties of the collagen-SPI film. The collagen-SPI self-assembled films could be used as novel wound dressings in the future./ |
