The introduction of CNF

Cellulose Nanofibrils (CNF), also called Nanofibrillated cellulose (NFC), Microfibrillated cellulose (MFC), or cellulose microfibril, microfibrillar cellulose, can be viewed as a cellulosic material, composed of expanded high-volume cellulose, moderately degraded and greatly expanded in surface area, and obtained by a homogenization. Its diameter is in the range of 20–60 nm and it has a length of several micrometers. Unlike CNC, CNF exhibits both amorphous and crystalline parts and presents a web-like structure. CNF normally is a viscous and shear-thinning aqueous gel at a very low concentration  (between 2 and 7%,  w/w).  This is one of the two main characteristics of such a  nanomaterial,  and the other is its ability to form a transparent film once it is dried.

Both these key properties are linked to its high specific area (at least ten times larger than that of cellulose fibers) and its extensive hydrogen-bonding ability.

Because CNF is more flexible, longer, and has a larger surface area than any other fibers, it is being developed for use in many scales, ranging from addition in food, biodegradable food packaging, pigment, selective delivery/separation, nanocomposites upon impregnation by polymers, and other medical and pharmaceutical applications.
