Crystalline structure analysis of all-cellulose nanocomposite films based on corn and wheat straws

Cellulose solution and nanocellulose were prepared from corn straw wheat then used to fabricate an all-cellulose nanocomposites film (ANF). The crystal structure (CS) of ANFs was analyzed by X-ray diffraction (XRD) Fourier transform infrared spectrometry (FTIR). Cellulose-I cellulose-II found coexist within regenerated cellulose films (RCF) ANFs. With the change content, proportions cellulose-I changed. transformation depend on raw material preparation method. When that had been extracted, type tended be transformed cellulose-II; proportion showed a tendency increase when content exceeded 1.5%. dissolved treated acid-alkali method, results did not follow clear pattern. However, straw, under extraction pattern with content. Though small amount can’t dominate cellulose-I, it could cause in disorder matrix.
