“…In addition to the barrier properties and related functional capabilities of nanocellulose-based layers, much research has focused on desirable attributes such as transparency Petersson and Oksman 2006;Nordqvist et al 2007;Shimazaki et al 2007;Ayuk et al 2009;Fernandes et al 2009Fernandes et al , 2010Fukuzumi et al 2009;Kim et al 2009;Nogi et al 2009;Petersson et al 2009;Sehaqui et al 2010;Hassan et al 2011;Pereda et al 2011Pereda et al , 2014Stevanic et al 2011;Yang et al 2011;Aulin et al 2012;Hu et al 2013;Li et al 2013a;Tome et al 2013;Khan et al 2014b;Kumar et al 2014;Kurihara and Isogai 2014;Tammelin and Vartiainen 2014;Ambrosio-Martin et al 2015b;Honorato et al 2015;Oun and Rhim 2015;Toivonen et al 2015a,b). Hu et al (2013) showed that nanocellulose films could be rendered conductive by deposition of tindoped indium oxide, while still retaining their transparency; solar cells prepared with such films were successfully demonstrated.…”

“…Such "curing" steps are considered below. Several research teams have described procedures whereby nanocellulosecontaining films have been heated or subjected to photo-initiation in order to bring about chemical reactions that cure the films (Shimazaki et al 2007;Stoica-Guzun et al 2013;Bai et al 2015a,b;Schade et al 2015). For example, the article and patent by Bai et al (2015a,b) describe the use of UV light to cure a formulation that included nanofibrillated cellulose, polyvinyl alcohol, a cross-linking agent, and a photo-initiator.…”

This review article was prompted by a remarkable growth in the number of scientific publications dealing with the use of nanocellulose (especially nanofibrillated cellulose (NFC), cellulose nanocrystals (CNC), and bacterial cellulose (BC)) to enhance the barrier properties and other performance attributes of new generations of packaging products. Recent research has confirmed and extended what is known about oxygen barrier and water vapor transmission performance, strength properties, and the susceptibility of nanocellulose-based films and coatings to the presence of humidity or moisture. Recent research also points to various promising strategies to prepare ecologically-friendly packaging materials, taking advantage of nanocellulose-based layers, to compete in an arena that has long been dominated by synthetic plastics. Some promising approaches entail usage of multiple layers of different materials or additives such as waxes, high-aspect ratio nano-clays, and surface-active compounds in addition to the nanocellulose material.While various high-end applications may be achieved by chemical derivatization or grafting of the nanocellulose, the current trends in research suggest that high-volume implementation will likely incorporate water-based formulations, which may include water-based dispersions or emulsions, depending on the enduses.

As of November 2016, a search of this combination of terms showed about as many publications since the start of 2015, compared to all preceding years combined. Given such an acceleration of research around the world, it makes sense to ask whether this high amount of research effort has yet borne significant fruit. In light of this question, the emphasis of this review article is on research publications that shed light on known challenges to the successful implementation of nanocellulose products to enhance the performance of packaging.In principle, a nano...

“…With the various processes for generating NC, it is possible that it can enhance epoxy elastomer and act as a good reinforcement for transparent composite coatings (Shimazaki et al 2007). The inclusion of NC in epoxy remarkably improves the thermal and mechanical behavior of the composite films, as well as its transparency (Steele et al 2012;Cross et al 2013).…”

Anticorrosion Properties of Epoxy/Nanocellulose Nanocomposite Coating

Nanocellulose (NC) is an attractive reinforcement agent that can be incorporated into protective coatings because it is a renewable, biodegradable, and biocompatible polymer resource. In this study, a series of epoxy resin-based nanocomposites were prepared in the form of coatings with various amounts of NC loadings, and the coatings were applied onto mild steel at room temperature. The characterizations of the NC and nanocomposites were performed via X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and Fourier transform infrared spectroscopy (FTIR). The thermophysical properties of the nanocomposites were evaluated using differential scanning calorimetry (DSC) and thermogravimetry (TGA) analyses. The transparency of the nanocomposite specimens was examined by ultraviolet visible (UV-Vis) spectroscopy in the range of 300 to 800 nm. The corrosion protection properties of the coated mild steel substrates immersed in a 3.5% NaCl solution were studied comparatively by electrochemical impedance spectroscopy (EIS). The results showed that all of the nanocomposite coatings with NC noticeably influenced the epoxy-diamine liquid pre-polymer, both physically and chemically. Furthermore, the 1 wt.% NC nanocomposite coating system was found to have the most pronounced anti-corrosion properties, as confirmed by a 30-day EIS study.

“…The cellulose fibers have established great industrial applications, however the insufficient manufacturing technology hinder their commercial applications 11 . Cellulose, in its nano form, has great potential in emerging medical and environmental applications and it has proven to be a good heat transfer material [12][13][14] . Cellulose fiber has contributed in its use in paper and other fiber based composite materials in adsorbents, textile industry, cosmetics and medical fields.…”
