Cellulose Whisker Nanocomposites

This section discusses the results of reactive molding of CW nanocomposites using FA as a polymerizable solvent medium to produce CW-PFA nanocomposites. Cellulose whiskers are not commercially available, and therefore, they were prepared by hydrolysis of MCC with sulfuric acid. The preparation of the CW was followed by their thorough morphology characterization, and finally, by the polymerization of FA to PFA in their presence. To characterize the polymerization behavior and to investigate how the presence of CW influences the polymerization of FA, FTIR spectra were collected before and during the resinification process. Finally, characterization of the thermal stability of the CW-PNC, as measured by TCA, is discussed and compared to the pure polymer. The results provide a useful qualitative measure of the CW dispersion in the cured PNC. [Pg.140]

Chauve et al. [253] utilized the same technique to examine the reinforcing effects of cellulose whiskers in EVA copolymer nanocomposites. It was shown that larger energy is needed to separate polar EVA copolymers from cellulose than for the nonpolar ethylene homopolymer. The elastomeric properties in the presence of spherical nanoparticles were studied by Sen et al. [254] utilizing Monte Carlo simulations on polypropylene matrix. They found that the presence of the nanofillers, due to their effect on chain conformation, significantly affected the elastomeric properties of nanocomposites. [Pg.76]

Electrospinning processes are used to prepare nanocomposite fiber mats. In order to prepare nanocomposite fiber mats, mixtures containing the polymer solution and cellulose whiskers solution are placed in the appropriated electrospinning setup. Peresin et al. [128] have produced nanocomposite mats of poly (vinyl alcohol) (PVA) reinforced with cellulose nanocrystals using this electrospinning technique. Smooth nonwoven mats with homogeneous nanofibers were obtained. Park et al. [129] have also incorporated cellulose whiskers into nanofibers of polyethylene oxide (PEO) by the electrospiiming process. [Pg.37]

Van den Ber et al. [166] has prepared nanocomposites of semi conducting polymers reinforced with tunicate cellulose whiskers with a typical diameter or around 20 nm. The results showed that the nanocomposites synergistically combine the electronic characteristic of the conjugated polymers with the improved mechanical properties of the cellulose scaffold. Other studies suggest that cellulose whisker can be used for electrical applications such as the creation of circuitry in a special kind of smart paper [167]. [Pg.44]
