    Three solvents of different polarities (water, methanol and 1% NaOH
    solution) were used to extract dyes that produced different shades from
    dried sunflower (Helianthus annuus) petal. The extraction procedures
    using different solvent types were carried out separately. The dye extracts
    were thereafter subjected to Fourier Transform Infrared Spectrometry
    (FT-IR) analysis for characterization in terms of functional groups. The
    intensities of the... More

    Study of Hydrophilic Properties of Polysaccharides

    Michael Ioelovich

    Article ID: 4181    DOI:
    240  (Abstract) 115  (Download)


    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

    There are two common types of polymers (thermoplastics and thermosets), which have been classified by various methods depending on their molecular structures. 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
