Cellulose is a polysaccharide made up of repeating 1,4-(J-hydroglucose imits coimected to each other by p-ether linkages and is the most abundant natural biopolymer in the world. Cellulosic fibers are broadly defined as fibers from plants or plant-based materials which contain cellulose and is drawn out into fibers for several applications. The long linear chains of cellulose permit the hydroxyl functional groups on each hydro-glucose

Extrusion and impregnation, electrospinning, and multilayer films are other processes applicable for reinforced nanocomposites. Thus, preparation of cellulose whiskers reinforced with polylactic acid nanocomposites (by melt extrusion carried out by pumping the suspension of nanocrystals into the polymer melt during the extrusion process), using polyvinyl alcohol as a compatibilizer for the dispersion of cellulose whiskers within the polylactic acid matrix, was reported (de Menezes et al. 2009) bacterial cellulose whiskers incorporated into poly(oxyethylene) nanofibers by electrospinn to enhance the mechanical properties of electrospun fibers (Peresin et al. 2010) or the use of the layer-by-layer assembly technique, which maximizes the interaction between cellulose whiskers and a polar polymeric matrix (Bruno et al. 2009 Aulin et al. 2010), are some examples of nanocomposites reinforced by the last three methods.
