Abstract
The present research work deals with the characterization of blend films obtained by mixing silk fibroin SF and hydroxypropyl methylcellulose HPMC solutions Structural chemical surface morphology mechanical and thermal property changes of silk fibroin by the addition of HPMC were investigated by Xray diffraction XRD Fourier transform infrared spectroscopy FTIR scanning electron microscopy SEM universal testing machine UTM thermogravimetric TGA and differential scanning calorimetry DSC The results indicate that with the introduction of HPMC the interactions between SF and HPMC in the blend films induced the conformation transition of SF from random coil form or silk I to βsheet structure or silk II form The SF/HPMC blend films are flexible and showed enhanced mechanical properties also the thermal stability of the films was improved significantly
