Abstract: The invention relates to a method for producing a modified cationized polysaccharide. The method comprises preparing a reaction slurry by mixing of a starting material comprising a polysaccharide, preferably cellulose, and an alkaline liquid medium comprising an organic liquid, allowing the polysaccharide to interact with the alkaline liquid medium in the reaction slurry at a pre-treatment temperature under a pre-determined reaction time, and adjusting the temperature of the reaction slurry to modification temperature, which is less than the boiling point of the alkaline liquid medium. A cationizing agent and an alkylation agent, which comprises an epoxy group, are added to the reaction slurry at the modification temperature, and the polysaccharide is allowed to react with the alkylation agent and the cationizing agent, preferably under inert atmosphere, and obtaining a modified cationized polysaccharide product in solution form. The invention relates also to the modified cationized polysaccharide and its use as flocculation agent.

Abstract: A hemostatic material is described, which eliminates the risks of conventional chitosan-derived products, such as the onset of shellfish allergy and endotoxin contamination, can be used safely for more people, and has an antibacterial property and a hemostatic function that widely-used hydrogels lack, and a wound dressing containing the same. A hemostatic material containing cationized cellulose and a wound dressing containing the hemostatic are described. At least one of hydroxyl groups of the cationized cellulose is modified with —R2—N+(R3)(R4)(R5).X−, other hydroxyl groups of the cationized cellulose have —H, or —(CH2CH2O)m—H, R2 represents C1-6 alkylene, C2-6 hydroxyalkylene, —(CH2CH2O)1—, or a combination thereof, 1 represents 1 or 2, m represents 1 or 2, and X− may represent an anionic group.

Abstract: In accordance with some embodiments of the present invention, a composite material is prepared by blending a bio-derived filler into a polymer, wherein the filler includes a diene-modified cellulosic nanomaterial (e.g., cellulose nanocrystals (CNCs) and/or cellulose nanofibrils (CNFs) functionalized to contain a diene) and a dienophile-modified cellulosic nanomaterial (e.g., CNCs and/or CNFs functionalized to contain a dienophile). The modulus of the composite material is reversibly controllable by adjusting a degree of crosslinking between the diene-modified cellulosic nanomaterial and the dienophile-modified cellulosic nanomaterial. This degree of crosslinking is thermally reversible. On one hand, the degree of crosslinking may be increased via a Diels-Alder (DA) cycloaddition reaction at a first temperature, thereby increasing the modulus of the composite material. On the other hand, the degree of crosslinking may be decreased via a retro-DA reaction at a second temperature higher than the first temperature, thereby decreasing the modulus of the composite material.
