“…Not only Atef et al but other research groups [61,62] too showed that due to good dispersion, low content of nanofiller (CNC) in polymer matrix (polylactide) is the best in terms of enhancement of mechanical properties. This hypothesis is also supported by this and our previous work [28,40], but stays in opposite to Khan et al [63] who claimed that 5% of CNC is optimal for chitosan. It comes as no surprise that aspect ratio of a filler, its interaction with polymer matrix, and uniform dispersion of filler are the main factors limiting mechanical properties of composites [63].…”

In this paper, ionic liquid treatment was applied to produce nanometric cellulose particles of two polymorphic forms. A complex characterization of nanofillers including wide-angle X-ray scattering, Fourier transform infrared spectroscopy, and particle size determination was performed. The evaluated ionic liquid treatment was effective in terms of nanocrystalline cellulose production, leaving chemical and supermolecular structure of the materials intact. However, nanocrystalline cellulose II was found to be more prone to ionic liquid hydrolysis leading to formation larger amount of small particles. Each nanocrystalline cellulose was subsequently mixed with a solution of chitosan, so that composite films containing 1, 3, and 5% mass/mass of nanometric filler were obtained. Reference samples of chitosan and chitosan with micrometric celluloses were also solvent casted. Thermal, mechanical, and morphological properties of films were tested and correlated with properties of filler used. The results of both, tensile tests and thermogravimetric analysis showed a significant discrepancy between composites filled with nanocrystalline cellulose I and nanocrystalline cellulose II.

“…This finding indicated that good compatibility between the seaweed and the OPS nanofillers was achieved, in which the TS of the nanocomposite films were enhanced by the presence of OPS nanoparticles compared to the blank seaweed film. This phenomenon could be due to the high specific surface area and uniform dispersion of the nanoparticles in the matrix, and good bonding between the hydrophilic oil palm nanoparticles and seaweed with the presence of hydroxyl groups (-OH groups), which could provide better filler-matrix interfacial interactions and also allow for the effective transfer of stress through a shear mechanism from the matrix to the particles (Huq et al 2012;Khan et al 2012;Mohaiyiddin et al 2013;Zarina and Ahmad 2014;Rosamah et al 2016;Abdul Khalil et al 2016). Hence, it was believed that the nanocomposite film could sustain greater loads when up to 20% of OPS nanofillers were incorporated.…”

Oil Palm Shell Nanofiller in Seaweed-based Composite Film: Mechanical, Physical, and Morphological Properties

et al. 2017

View full text Add to dashboard Cite

Composite films that utilize seaweed as a matrix and oil palm shell (OPS) nanoparticles as a reinforcing material were developed. The effects of loading OPS nanoparticle (0%, 1%, 5%, 10%, 20%, and 30%) into seaweed films were determined by analyzing the physical, mechanical, and morphological properties of the films. The seaweedbased film incorporated with OPS nanoparticles at a high concentration (20% w/w) achieved the highest tensile strength (44.8 MPa) and Young's Modulus (3.13 GPa). However, the film's hydrophobicity (contact angle = 47.3º) and percentage of elongation at break (2.10%) were reduced. Moreover, it was observed that excessive loading of nanofillers (> 20%) reduced the tensile strength and hydrophilicity of the film. This phenomenon was attributed to the agglomeration of OPS nanoparticles and the formation of large voids on the film surface. Thus, the relative effectiveness of the various tested nanofiller contents in enhancing the mechanical strength of the composite film were found to be ranked in the following order: 20%, 10%, 5%, 30%, and 1%.

“…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...
