“…and synthetic polymers (PVA, polystyrene, polylactic acid, etc.) results in the formation of new composite materials with enhanced or special properties and applications in different kinds of areas, as reported by many other researchers [10,11,12,13,14,15]. Due to environmental concerns, the composite materials should be biodegradable and recyclable, reprocessable, and reusable.…”

In this study microcrystalline cellulose (MCC) was oxidized by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation. The treated cellulose slurry was mechanically homogenized to form a transparent dispersion which consisted of individual cellulose nanofibers with uniform widths of 3–4 nm. Bio-nanocomposite films were then prepared from a polyvinyl alcohol (PVA)-chitosan (CS) polymeric blend with different TEMPO-oxidized cellulose nanofiber (TOCN) contents (0, 0.5, 1.0 and 1.5 wt %) via the solution casting method. The characterizations of pure PVA/CS and PVA/CS/TOCN films were performed in terms of field emission scanning electron microscopy (FESEM), tensile tests, thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The results from FESEM analysis justified that low loading levels of TOCNs were dispersed uniformly and homogeneously in the PVA-CS blend matrix. The tensile strength and thermal stability of the films were increased with the increased loading levels of TOCNs to a maximum level. The thermal study indicated a slight improvement of the thermal stability upon the reinforcement of TOCNs. As evidenced by the FTIR and XRD, PVA and CS were considered miscible and compatible owing to hydrogen bonding interaction. These analyses also revealed the good dispersion of TOCNs within the PVA/CS polymer matrix. The improved properties due to the reinforcement of TOCNs can be highly beneficial in numerous applications.

“…Particularly, PHB/cellulose nanocrystal (CNC) composites could also reduce additive migration to the food material in food packaging applications at low loadings, indicating that this material presents operational stability and can be used for products with long‐term storage at room temperature . Nanoscaled cellulose fibers are promising candidates for the preparation of bionanocomposites, owing to their high abundance, strength, stiffness, low weight, and biodegradability …”

Paper presents low water vapor barrier capacity that is considered a limitation for its use in packaging applications. Therefore, the effect of using polyhydroxybutyrate (PHB)‐based coatings containing a plasticizer [Tributyrin (TB)] and cellulose nanocrystals (CNCs) in a bilayer configuration with paperboard is investigated in this work. PHB/paperboard composites are obtained by compression molding. It is found that the addition of TB and CNC in the coating formulation favored both the interaction between layers in the final composite and the enhancement of tensile properties for PHB/paperboard composites. Also, it is proved that water vapor permeation of bilayer composites is reduced by the addition of CNC in the PHB‐based layer. Disintegration test of the films has also been carried out under composting conditions, according to the standard ISO 20200, demonstrating that all the studied samples reached more than 90% of disintegration after 49 days of incubation. © 2018 Wiley Periodicals, Inc.

“…The rapid cooling technique employs flexible and faster temperature alterations in the reaction system which could significantly affect the surface, thermal properties, macromolecular structural stability, and ordered structure of the crystals growth behavior of the nanomaterials. The colloidal (Zhong et al, 2012), viscous (Shafeiei-Sabet, Hamad, & Hatzikiriakos, 2013, viscoelastic (Lu, Hemraz, Khalili, & Boluk, 2014), rheological (Ching et al, 2016;Shafeiei-Sabet et al, 2013), and dynamic rheological phase behaviors (Chen et al, 2013) of nanocrystalline celluloses has been studied and (Mhd Haniffa, Ching, Abdullah, Poh, & Chuah, 2016) incorporated with several reaction conditions.…”

Recently, surface functionality and thermal property of the green nanomaterials have received wide attention in numerous applications. In this study, microcrystalline cellulose (MCC) was used to prepare the nanocrystalline celluloses (NCCs) using acid hydrolysis method. The NCCs was treated with TEMPO [(2,2,6,6-tetramethylpiperidin-1-yl)oxy radical]-oxidation to prepare TEMPO-oxidized NCCs. Cellulose nanofibrils (CNFs) also prepared from MCC using TEMPO-oxidation. The effects of rapid cooling and chemical treatments on the thermo-structural property studies of the prepared nanocelluloses were investigated through FTIR, thermogravimetric analysis-derivative thermogravimetric (TGA-DTG), and XRD. A posteriori knowledge of the FTIR and TGA-DTG analysis revealed that the rapid cooling treatment enhanced the hydrogen bond energy and thermal stability of the TEMPO-oxidized NCC compared to other nanocelluloses. XRD analysis exhibits the effect of rapid cooling on pseudo 2 helical conformation. This was the first investigation performed on the effect of rapid cooling on structural properties of the nanocellulose.
