Cellulose Nanofiber solution

Product Name

^{Name：Cellulose Nanofiber solution}

Product Overview

 

^{Nanocellulose solution is usually a milky white liquid with good dispersibility and stability.}

^{The diameter of cellulose fibers is usually between 15-25 nanometers, and the length can reach 200-300 nanometers, which makes nanocellulose solutions have extremely high specific surface area and surface activity. The properties of nanocellulose solutions depend on factors such as the type, concentration, surface chemical properties, and solvent of nanocellulose. Generally speaking, nanocellulose solutions have a certain viscosity, and the viscosity increases with the increase of nanocellulose concentration. When the concentration of nanocellulose is low, the solution exhibits characteristics similar to Newtonian fluids; When the concentration is high, the solution may exhibit non Newtonian fluid characteristics, such as shear thinning.}

^{The stability of nanocellulose solution is also an important property. By appropriate surface chemical modification or adding stabilizers, the stability of nanocellulose solutions can be improved to prevent aggregation and precipitation of nanocellulose. For example, adding some surfactants or polymers to nanocellulose solutions can improve the stability of the solution through electrostatic repulsion or steric hindrance. Nanocellulose is mainly treated with chemical reagents to decompose cellulose into nanocellulose. Among them, acid hydrolysis is a commonly used chemical method, usually using sulfuric acid to hydrolyze cellulose. Under certain temperature and time conditions, the amorphous region of cellulose is hydrolyzed while the crystalline region remains, forming cellulose nanocrystals. The cellulose nanocrystals prepared by this method have high crystallinity, but require acid recovery and treatment to reduce environmental pollution.}
