“…After purification and derivatization, chitosan can be dissolved in water at suitable pH and solution-cast to films (Chenite et al 2001). Hosokawa et al (1990Hosokawa et al ( , 1991 reported a novel and biodegradable composite film derived from chitosan and MFC Table 4 continued that has a high oxygen-gas barrier capacity and is hydrophilic but insoluble in water. Composite films were prepared in the ranges between 0 and 40 wt% chitosan in MFC.…”

Microfibrillated cellulose and new nanocomposite materials: a review

Due to their abundance, high strength and stiffness, low weight and biodegradability, nano-scale cellulose fiber materials (e.g., microfibrillated cellulose and bacterial cellulose) serve as promising candidates for bio-nanocomposite production. Such new high-value materials are the subject of continuing research and are commercially interesting in terms of new products from the pulp and paper industry and the agricultural sector. Cellulose nanofibers can be extracted from various plant sources and, although the mechanical separation of plant fibers into smaller elementary constituents has typically required high energy input, chemical and/or enzymatic fiber pre-treatments have been developed to overcome this problem. A challenge associated with using nanocellulose in composites is the lack of compatibility with hydrophobic polymers and various chemical modification methods have been explored in order to address this hurdle. This review summarizes progress in nanocellulose preparation with a particular focus on microfibrillated cellulose and also discusses recent developments in bio-nanocomposite fabrication based on nanocellulose.

“…1 In particular, research on the interaction of chitosan with wood or wood components, which are very useful biomass resources, has become of interest in recent years. [2][3][4][5][6][7][8][9][10] In our previous report, the interaction of chitosan with cellulose model compounds based on the Maillard reaction was investigated. 11 It was clarified that chitosan was markedly modified by increasing the amount of the compounds added.…”

The Maillard reaction between chitosan and hemicellulose model compounds such as mannose, xylose, and glucuronic acid was investigated. Chitosan and the compounds were dissolved in 1% acetic acid and were dried at 508C. In an analysis of the film obtained, weight increase, color difference, FTIR, relative amount of free amino groups, insolubility to dilute acetic acid, and tensile properties were measured. The film weight increased gradually as the compounds were added, and the color difference changed significantly. In addition, the relative amount of free amino groups decreased rapidly, and the insoluble matter increased markedly. In particular, xylose brought about drastic changes in a small amount addition. According to the results of FTIR spectra, the cleavage of sugar unit of chitosan and the formation of heterocyclic compounds were observed in all compounds. The formation of carbonyl and carboxyl groups was observed with the addition of a large amount of the compounds. The tensile strength was improved in 10-20 wt % additions of the compounds.

“…13 This polymer blend offers greater economic advantages. 14 The applications of polymer and polymer blend generally depend on their mechanical properties; however, their thermal characteristics must also be considered. 15 The temperature of the thermal degradation of polymers must be determined before they can be used in thermal applications.…”

A kinetic study of thermal degradations of chitosan/polycaprolactam blends

We have used FT-IR spectra to explain the effects of hydrogen bonding between chitosan and polycaprolactam (PA6). A dynamic mechanical analysis study suggested that the optimum chitosan and PA6 miscibility under the conditions of this experiment were obtained at a blending ratio of 40:60. We studied the thermal degradation of chitosan blended with PA6 (chitosan/PA6) by thermogravimetric analysis and kinetic analysis (by the Ozawa method). Dry chitosan and PA6 exhibited a single stage of thermal degradation and chitosan/PA6 blends having >20 wt% PA6 exhibited at least two stages of degradation. In chitosan/PA6 blends, chitosan underwent the first stage of thermal degradation; the second stage proceeded at a temperature lower than that of PA6, because the decomposition product of chitosan accelerated the degradation of PA6. The activation energies of the blends were between 130 and 165 kJ/mol, which are also lower than that of PA6.
