“…A strong shear thinning behavior was observed for aqueous dispersions of lignin-containing cellulose nanoparticles derived from soy hulls and was found to be of interest for rheology modification, coatings, and films . Relevant to this work, the previous efforts discussed water drainage during film formation depending on particle morphology and lignin content . Likewise, recent work has pursued the effects of fibril heterogeneity in micro/nanofibrillated cellulose and fibril width distribution in microfibrillated cellulose (MFC) on the rheological characteristics of the respective suspension .…”

The rheological behavior of aqueous suspensions of lignocellulose nanofibrils (LCNFs) is investigated systematically by considering the coupled effect of residual lignin and LCNF morphology. The LCNF was obtained by high-energy fluidization of TEMPOoxidized mechanical fibers, followed by size fractionation (fibril widths of ∼5, ∼9, and ∼18 nm). The nanofibril width and the corresponding fibril−fibril interactions are strongly influenced by the presence and distribution of lignin in the respective fractions, either retained on the fibril surface or as free structures present in the finest size fraction. All samples containing lignin display dilatancy, typifying gel suspensions with aggregated hydrophobic particles. Fine fractionated samples display strong gel behavior. The coarse fractionated sample, by contrast, shows a greater tendency to flocculate via entanglement and displays less gel-like characteristics; hence, it dewaters more freely.

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 global oil production reached almost 21 million tons in 2010 . Thus, an enormous volume of residues are generated, mainly EFB fibers, which are proposed here for the production of micronano fibers by methods different than those reported so far by us , and others. ,− One critical issue common to coir and EFB fibers is the high lignin content, as high as 45%. Therefore, any attempt in utilization should consider preserving this component as the only way to make any industrial effort truly sustainable.…”

Autohydrolysis and microemulsion treatments followed by microfluidization are employed to isolate micro- and nanofibrillar cellulose (MNFC) from coir fibers and palm tree empty fruit bunches (EFB) with residual lignin content of ∼24 and ∼31 wt %, respectively. The fibers and associated MNFC are characterized in each treatment for their chemical, structural, and thermal properties. The most significant findings include the fact that two MNFC populations are produced, with distinctive structural differences and characteristic lateral dimensions of 20–70 nm and 1–3 μm. The lignin distribution after possible recondensation occurred in the form of nanodroplets. Finally, a correlation between thermal degradation of MNFC with spatial arrangement of lignin is hypothesized and a defibrillation mechanism is proposed. The detailed structural and thermochemical analyses presented here are expected to facilitate further interest in the development of new materials from MNFC isolated from coir and EFB, two abundant bioresources that are most suitable for their valorization.
