Organic Nanoreinforcements Utilized for Preparation of Nanocomposite Packaging Materials

A new approach to improve the properties of plastics is the using of fillers. Nanoreinforcements are a class of fillers that have a dimension below 100 nm and lead to produce nanocomposites. The nanoreinforcements used in the fabrication of nanocomposites are divided to organic and inorganic materials. Cellulose nanocrystal, chitin and chitosan nanofibers and also starch nanoparticles are examples of organic nanomaterials. In this review paper, the structure and characteristics of organic nanofillers have been investigated. Moreover, their improving effect on the functional properties of polymers and biopolymers has been studied. Also, in the recent years the application of these nanomaterials has new insights such as enzyme immobilization and fabrication of nanohybrids. The new applications of organic nanomaterials that determine the future of research in this area, has been investigated in this paper.
