Compatibility of fibroin/chitosan and fibroin/cellulose blends studied by thermal analysis
- 126 Downloads
The compatibility of fibroin with chitosan was confirmed by means of the DSC method, measuring thermal characteristics of blends of these components in the form of films obtained from solutions in a common solvent such as HFIP. Polymers have the general temperatures of glass transition and the beginnings of degradation of crystal areas. The TG analysis of fibroin/cellulose blends in the form of films obtained from NMMO solutions has shown that the thermal stability of such blends is higher than that of cellulose owing to the strong interaction between the components, which is also shown by the decreased mass loss rate of the blend during thermal treatment, as compared to that of individual components.
