“…Aulin et al (2013) were able to tune the barrier properties of the films by varying the procedural details of successive adsorption of polyethyleneimine and nanocellulose. Marais et al (2014) demonstrated unusually high straining ability of such films. They also demonstrated a large difference in properties, depending on which of the successive layers was the last to be deposited in a multilayer film structure.…”

“…Some researchers have applied the same approach to preparing films incorporating nanocellulose, essentially substituting the nanocellulose suspension in place of the negatively charged polyelectrolyte solutions typically used in such procedures (Wågberg et al 2008; Aulin et al 2009b Aulin et al , 2010b Aulin et al , 2013 de Mesquita et al 2010;Li et al 2013b;Marais et al 2014). Alternatively, it is possible to convert nanocellulose to a positively charged form and make the opposite substitution (Aulin et al 2010b).…”

“…Secondly, the tiny dimensions of nanocellulose imply a high exposure to its surroundings. The issue of biodegradation has been emphasized in studies in which nanocellulose was used in composite structures with other natural film-forming materials (Lu et al 2008;Ma et al 2008;Cheng et al 2009;Wan et al 2009; Azeredo et al 2010;Bras et al 2010;Khan et al 2010Khan et al , 2012Khan et al , 2014bSiro and Plackett 2010;da Silva et al 2012;Hassan et al 2012;Johnsy and Siddaramaiah 2012;Tang et al 2012; Baheti and Militky 2013; ChingaCarrasco et al 2013;Ollier et al 2013; Bhardwaj et al 2014;Dehnad et al 2014a;Fortunati et al 2014;Ghaderi et al 2014;Khalil et al 2014;Kumar et al 2014;Marais et al 2014;Reddy and Rhim 2014;Song et al 2014;Yang et al 2014; Azizi Samir et al 2015; Feng et al 2015a;Figueiredo et al 2015;Honorato et al 2015;Lavoine et al 2015;Li et al 2015a;Lu et al 2015; Youssef et al REVIEW ARTICLE bioresources.com .

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...

“…The use of PECs and PEMs have also found their way into the field of pulping and papermaking (Petzold and Lunkwitz 1995;Petzold et al 1996;Gernandt et al 2003;Hubbe et al 2003Hubbe et al , 2005Gärdlund et al 2005;Lofton et al 2005;Torgnysdotter and Wågberg 2006;Myllytie et al 2009;Renneckar and Zhou 2009;Lin and Renneckar 2011;Granberg et al 2012;Ankerfors and Wågberg 2013;Marais et al 2014). The use of PECs and PEMs in papermaking is somewhat expected, since the properties of paper and retention of fillers commonly have been tailored by additions of polyelectrolytes, in single or dual systems, for a long time (Hubbe 2006).…”

In-situ analysis of polyelectrolyte complexes by flow cytometry

Polyelectrolyte complexes (PECs) from common papermaking additives were prepared at different cation/anion ratios, resulting in colloidal light scattering particles. The polycations were cationic starches and polyDADMACs, while the polyanions were different carboxymethyl celluloses. The PECs were studied by turbidity measurements, as well as by flow cytometry (FCM). Turbidity maxima were detected close to the theoretical neutralization point of the polycation and polyanion. The turbidity response of the PEC mixtures varied with polyelectrolyte charge density. The PECs were in most cases quite stable over 24 h, but certain combinations resulted in unstable particles over time. Flow cytometry of PECs revealed clear populations of hydrophilic particles. The light scattering properties of PECs in side direction (SSC) and forward direction (FSC) were recorded for the different PEC combinations. The determined FSC and SSC offered information about very different PEC properties, and a new term was suggested for better understanding the mechanisms behind PEC formation; FSC/SSC. It was suggested that the determined FSC/SSC values were connected to the structural density of different particles. The premise was tested by analyses of solid, dense particles as well as swollen, soft particles. In addition to this, the hydrophobicity of PECs was determined by FCM. It was seen that the PECs were quite hydrophilic overall and that the measured hydrophobicities were lowest around the theoretical point of neutralization. Finally, the behavior of a coagulating PEC mixture as a function of contact time was studied with FCM.

“…Polyelectrolyte/polyelectrolyte or polyelectrolyte/nanoparticles multilayers created by LbL assembly can also be deposited on wood (Lin et al 2008;Renneckar and Zhou 2009). The modified fibers have improved physical properties and special functionalities such as high scalability (Marais et al 2014), high porosity (Lu et al 2007), electroconductibility (Agarwal et al 2009), magnetism (Cranston and Gray 2006), flame resistance (Laufer et al 2012), superhydrophobicity, (Zhang et al 2012a) etc. (Zhou et al 2010;Zamarreño et al 2011).…”

A hydrophilic wood surface was transformed to become superhydrophobic by layer-by-layer (LbL) assembly of polyelectrolyte/titanium dioxide (TiO2) nanoparticles multilayers and subsequent hydrophobic modification with 1H, 1H, 2H, 2H-perfluoroalkyltriethoxysilane (POTS). The chemical composition of the wood samples before and after treatment was characterized by energy dispersive X-ray analysis (EDXA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). These analyses showed that a highsurface-roughness film of TiO2 nanoparticles deposited by LbL became combined on the wood surface with a low-surface-energy thin layer of POTS. The microstructure and the hydrophobicity of the wood samples were analyzed by scanning electron microscope (SEM) and contact angle measurements, respectively. The morphology and the values of water contact angle (WCA) demonstrated that the reaction pH and number of self-assembled layers were the main factors affecting hydrophobic wood samples. After assembly with 5 or more multilayers, the wood surface exhibited excellent superhydrophobicity with the highest WCA of 161°.
