Abstract
Description
technical field
[0001] The invention belongs to the field of medical devices, and in particular relates to a gel bandage and its preparation principle and preparation method. Background technique
[0002] Chitosan is the only alkaline polysaccharide among natural polysaccharides, but chitosan has poor water solubility and can only be dissolved in weak acids, but insoluble in water and many organic solvents, which limits its application to a large extent. Therefore, the hydroxypropyl group is quoted on the chitosan molecule, which changes the intermolecular space structure and weakens the hydrogen bond between chitosan molecules and intramolecules, thereby improving and enhancing its water solubility and reactivity. And hydroxypropylated chitosan has good water solubility, antibacterial and adsorption properties. The Chinese name of hydroxypropyl chitosan is hydroxypropyl chitosan, and the English name is Chitosan, N-(2-hydroxypropyl). Chitosan oligosaccharide, also known a...
