Lignin nanocomposites

Lignin is a biopolymer and one of the main constituents of woody plants where it plays the role of lining agent and is comparable in this respect to cement in steel reinforced concrete. Polymer nanocomposites containing biopolymers such as cellulose, lignin, starch, proteins, etc. are the object of recent numerous studies and are known also as bio-nanocomposites. This paper deals with lignin use in various polymer nanocomposites. It presents the preparation and uses of nanolignin as a filler and lignin uses as a matrix or a matrix component in polymer nanocomposites.
