Abstract

Bombyx Mori silk and polyvinyl acetate (PVAc) were combined in different ratios to form protein–synthetic polymer blend films. The effect of silk content on PVAc blends was investigated by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). SEM images revealed that silk and PVAc in different ratios can form a homogeneous morphology. FTIR spectra suggested structural changes in the films such as the formation of beta-sheet crystals with the increase of PVAc content in the blends. A single glass transition temperature for each blend was found in DSC curves, indicating that a good miscibility existed in the blends. These protein–polymer blend films may be useful for a variety of applications in materials and biomedical fields.
