Notes:
The effects of sodium alginate on the physical properties of fibroin membranes, such as rupture elongation, rupture strength, water absorption, and thermal properties, were investigated. The experimental results showed the β-form crystal and β-form molecular conformation increased due to the increase of intermolecular hydrogen bonds, such as C=O---HN and C=O---HO. The kind of intermolecular interaction and β-form molecular conformation of polymer blends were clarified by 13C-NMR and infrared spectroscopy. The increase in β-form crystal was examined by X-ray analysis. Further, membranes were characterized by thermogravimetric analysis (TGA) and by determining their water contents and tensile properties.
