4. Structural Elements in Native Celluloses
Abstract : In this thesis, a schematic model for the structure ofaggregated cellulose I fibrils is proposed. The model consistsof a crystalline fibril core surrounded by less orderedcellulose forms. These cellulose forms are fibril surfacesaccessible to water, fibril surfaces inaccessible to water andpara-crystalline cellulose. READ MORE
