Degradation studies on plant cellulose and bacterial cellulose by FT-IR and ESEM

[摘要] As the most important polysaccharide on the planet, cellulose is considered as an unexhausted material which could be widely used. Because of its unique structure, cellulose shows special property of hydrolysis in acid and alkali solutions. Its ability of degradation was studied by FT-IR and ESEM. The two-region structure has different performances in acid hydrolysis and alkali hydrolysis. The result showed the hydrolysis occurred on the surface of the cellulose but the microfiber bundles were stable in the process. The crystal structure has transformed due to the reaction in NaOH solution because of the reformation of hydrogen bond to make the crystalline from Cellulose I into Cellulose II.
