ANPOLY’s nanocellulose is made from abundant natural resources and is renewable, biodegradable, high in strength and light in weight. In addition, due to the various advantages of nanocellulose, there are also various applications such as lightweight composite, packaging, filtration, cosmetics, and medical biomaterials.

There are several types of nanocellulose, and what ANPOLY offers are CNF (Cellulose Nanofiber) and CNC (Cellulose Nanocrystal). Although the criteria for distinguishing CNF and CNC are different depending on scholars, they are generally distinguished by shape and aspect ratio (diameter/length). CNF has a fibrous shape and an aspect ratio of more than 1/100, while CNC has a crystalline shape and an aspect ratio of less than 1/50. This difference is due to the manufacturing method, where CNF uses a mechanical method to maintain its overall fiber shape, while CNC is manufactured through acid hydrolysis (treatment of sulfuric acid) so that the amorphous region is melted by a strong acid and only the crystalline region remains.

Performance

ANPOLY’s nanocellulose has excellent gas barrier properties, strengthening physical properties, and viscosity with shear thinning.

In addition to the following functions, various functions can be given through surface modification.

# Gas Barrier


Nanocellulose has gas barrier properties due to its high crystallinity and strong hydrogen bonding. The crystalline region of nanocellulose is an impermeable region where gas molecules cannot pass, and the effects of crystallinity and hydrogen bonding create a tortuous path through which gas cannot pass through the film, improving gas barrier.



# Reinforcement /
   Light weighting


Nanocellulose has a high mechanical property with a theoretical modulus of elasticity of about 100-200 GPa and a tensile strength of about 4.9-7.5 GPa in its crystal form. These mechanical properties are higher than most metals, ceramics, alloys, and synthetic polymers, and are lightweight due to their low density of around 1.6 g cm-3.



# Rheological property


Nanocellulose is changed to sol when an external force is applied due to urination, which is a change in viscosity due to external force, and when there is no external force, the viscosity increases and returns to gel form.
