Abstract:
In this research, the structural characteristics, specific surface area, sorption of water vapor, and wetting enthalpy of various polysaccharides (cellulose, hemicelluloses, starch, pectin, chitin, and chitosan) have been studied. It was confirmed that crystallites are inaccessible for water, and therefore water molecules can interact only with polar groups in noncrystalline (amorphous) domains of biopolymers. The... More

The bonding of molecular chains is the fundamental physical difference between these two polymer types. The polymer types are named based on their general thermal and processing characteristics, and chemical structure,... More
