Chemistry and physics of cellulose and cellulose substance

Popis výsledku v původním jazyce

Cellulose is a fibrous, tough, water-insoluble substance, which is found in the protective cell walls of plants, particularly in stalks, stems, trunks and all woody portions of plant tissues. Knowledge of the supramolecular and hypermolecular structure of cellulose, accompanied by changes during its chemical or mechanical treatment, is important not only for technical or biomedical applications, but predominantly, as a novel approach to better understand and control the aging of cellulose materials, e.g., in paper and paper products and nano-composites. In the chapter is described and discussed in detail the basic chemistry of cellulose, the epimolecular characteristic of cellulose and lignocellulose materials as their supramolecular and hypermolecular characteristics. Connectivity of water and cellulose/cellulosic substances is also defined as the key component controlling the behaviour of all biomaterials. The interest was concentrated upon stable colloidal suspensions of cellulose microcrystallites exhibiting chiral nematic (cholesteric) ordering – a liquid crystalline cellulose suspension. Wet-web strength and wet tensile strength is a key functionality for tissue paper, paper towel, paperboard for packaging, cellulosic filter sheets and similar paper grades. Description of interactions in cellulosic fibrous slurries using enthalpiometric measurements is brought as well as. Existence of small water inclusions among cellulosic chains of the cellulose membrane was confirmed as well. It is practically impossible to form a fibrous bonding system of paper without a supporting tool to draw the mutually interacting fibre surfaces near, during the H-bond formation. Hydration Bonding/Antibonding Concept is thus summarised in detail followed by the rheosedimentation phenomenon and the description of thermoresponsive hydrated macro-, micro- and submicroreticular hydro-systems of cellulose. Compete vapours activities in cellulosic materials, i.e. competitive absorption mechanisms for condensation of water and essential oil in the porous structure of the paper matter are described in detail. Special kinetics of the swelling process in connectivity with recycling of cellulosic materials is typical for behaviour of these ones.
