综纤维素氢键模式的研究
Research on Hydrogen Bonding Patterns of Holo-cellulose by XRD and FT-IR
摘要
Abstract
The change of crystalline form and hydrogen bonding patterns of holo-cellulose during dilute acid hydrolysis process was analyzed by X-ray diffraction and FT-IR spectroscopy. The FT-IR spectra of hydrogen-banded OH stretching vibration were resolved into three bands for cellulose Ⅰ, assuming that all the vibration modes follow Gaussion distribution. Results showed that the crytallinity of cellulose and crystallite size increase after hydrolysis treatment. The relative contents of molecular hydrogen in three kinds of samples are 48.15％, 77.07％ and 55. 22％. It has been proved that cellulose chains mainly combine together by hydrogen bonding between molecules, while intramolecular hydrogen bonds are taking second place. Acid hydrolysis only influences the transformation of hydrogen bonding patterns while crystalline form has no change.关键词
