AbstractThe 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 CO‐‐‐HN and CO‐‐‐HO. The kind of intermolecular interaction and β‐form molecular conformation of polymer blends were clarified by13C–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
