Nanocellulose-Based Composites

Recently, nanocellulose has been the focus of an increasing number of works [33, 99-102] devoted to understanding such materials and their application. The nanocellulose incorporated 

An additional important question closely connected with the processing of these composites is low thermal stability of cellulose component The processing temperature of composites is restricted to about 200°C because lignocellulosic materials start to degrade near 230°C [145]. 

Various cellulose nanofibrils, nanociystals, and whiskers have been incorporated into pol5mier matrices to produce reinforced composites having significantly improved mechanical properties [146,147]. 

The use of nanocellulose as reinforcing fillers in poly(styrene-co-butyl acrylate] was first observed by Favier et al. [148]. They measured by the DMA method, in the shear mode, significant improvement in the storage modulus after adding tunicin whiskers 

Dufresne et al. [153] noted that surface adsorption of potyojq ethylene chains on the surface nanocrystals can improve dispersibility and thermal stability of nanocrystals during the melt processing of polyethylene based nanocomposites. The chemical modification of cellulose is a most effective approach to avoid irreversible agglomeration during drying, and enhance the adhesion between nanocellulose and nonpolar matrices [132]. Dufresne et al. [98] showed also, that chemical and physical compatibilization imparted by poly(ethylene glycol) and polyoxyethylene layers promoted the interfacial interaction between cellulosic nanoparticles and polystyrene.

The chapter covers a review of miscellaneous nanocomposites based on biodegradable pol5mier matrices and nanofillers. The first two parts discuss components of composites, renewable bionanofillers of natural origin, and biodegradable polymer matrices whereas the last part covers nanocellulose-based composites, also in terms of their potential use in high-tech applications in medicine as these are regarded to be the wave of the future.
