11 - Structural changes of cellulose and their effects on the OH/CH2 valency vibration range in FTIR spectra

Abstract

Several examples show that variations in the cellulose structure are reflected in the deconvoluted OH/CH2 vibration range of IR spectra. Thus differences in the celluloses from higher plants and from bacteria were found, the influence of water was proved, and changes caused by thermal and mechanical treatments were traced. The deconvoluted range of 2500 to 3700 cm−1 contains a great amount of information on the molecular and supramolecular structure of cellulose and its changes under chemical, thermal and mechanical influences.
