Chemical treatments increased the cellulose content, crystallinity, and thermal stability of soybean straw. Alkali treatment produced a mixture of polymorphs of cellulose I and II. Addition of chemically treated fibers improved the mechanical resistance of SPI film. H2O2 bleaching provided more effective delignification. Soybean straw treated with H2O2 yielded less soluble composite film.
