Product_introduction
Chitosan is insoluble in water and alkaline solutions, but soluble in most dilute acid solutions such as hydrochloric acid, acetic acid, etc. Under acidic conditions, the amino groups in chitosan molecules are protonated, giving them certain cationic properties.
Viscosity: The aqueous solution of chitosan has a high viscosity, which is related to factors such as molecular weight, solution concentration, temperature, and pH. Generally speaking, the larger the molecular weight and concentration, the higher the viscosity of the solution.
Biocompatibility: Chitosan has good biocompatibility and can interact with human tissues and cells without causing significant immune reactions. This has led to its widespread application in the biomedical field.
Biodegradability: Chitosan can be degraded by enzymes such as lysozyme in the human body, ultimately producing carbon dioxide and water, which are excreted from the body. Its degradation products have no toxic side effects on the human body, making it an environmentally friendly biomaterial.
Adsorption: Chitosan molecules contain a large number of polar groups such as amino and hydroxyl groups, which give them strong adsorption capacity. It can adsorb metal ions, organic matter, microorganisms and other substances, so it has important applications in environmental protection, food and other fields.
