There is an emerging quest for lightweight materials with excellent mechanical properties and economic production, while still being sustainable and functionalizable. They could form the basis of the future bioeconomy for energy and material efficiency. Cellulose has long been recognized as an abundant polymer. Modified celluloses were, in fact, among the first polymers used in technical applications; however, they were later replaced by petroleum-based synthetic polymers. Currently, there is a resurgence of interest to utilize renewable resources, where cellulose is foreseen to make again a major impact, this time in the development of advanced materials. This is because of its availability and properties, as well as economic and sustainable production. Among cellulose-based structures, cellulose nanofibrils and nanocrystals display nanoscale lateral dimensions and lengths ranging from nanometers to micrometers. Their excellent mechanical properties are, in part, due to their crystalline assembly via hydrogen bonds. Owing to their abundant surface hydroxyl groups, they can be easily modified with nanoparticles, (bio)polymers, inorganics, or nanocarbons to form functional fibers, films, bulk matter, and porous aerogels and foams. Here, some of the recent progress in the development of advanced materials within this rapidly growing field is reviewed.

“…The recent addition to the environmental scenario and sustainability in new product development, cellulose, more specifically, fibrillated or nanofibrillated cellulose (or cellulose nanofibers -CNFs) can play an extraordinary role (VALLE-DELGADO et al, 2016;HUBBE et al, 2017). CNFs have dimensions of approximately 5-60 nm in diameter and lengths of few micrometres; these nanofibers are produced through a mechanical fibrillation (friction), and in some cases with the aid of chemical or enzymatic pre-treatments, of cellulosic pulps (IWAMOTO et al, 2008;ISOGAI et al, 2011;KLEMM et al, 2011).…”

In a world seeking environmentally sustainable products, bio-resources are investigated as suitable replacements to oil-derived products. Tannin extracts represent one of the most abundant phenolic resources of the earth, with more than 200,000 T/year. These extractives are constituted mainly of polyphenolic compounds and they are used industrially for various purposes, including leather tanning, wine-making, and water clarification. However, condensed tannin extractives can also be easily polymerized, and the resulting bio-macromolecule can be exploited for other applications such as adhesives and coatings. In recent years, tannin-based polymers have also been used for the synthesis of fire-resistant insulation foams and outdoor wood preservatives. This bio-resource imparts also outstanding water resistance to wood plastic composites (WPCs) and gives great antioxidant activity to nanofibrillated cellulose films, which become an interesting material for "active packaging". This literature review covers these four innovative solutions made from tannin extractives from mimosa or black wattle (Acacia mearnsii) industrial powder and provides some basic information about the purification of the industrial tannin extract that can be suitable for more chemically specific usages.

“…Tiny and bilayer protein coated CLPs (mass ratio 1 g g -1 lignin) CLPs were linked on the CNF surfaces using esterification reaction between the carboxylic acid groups with hydroxyls of CNF [49,59]. For the analysis two drops of modified CLP dispersions were coated (4000 rpm, 1 min) on the CNF surface using a spin-coater from Laurell Technologies Corp., (USA).…”

Lignin has interesting functionalities to be exploited in adhesives for medicine, foods and textiles. Nanoparticles (NPs) <100 nm coated with poly(L-lysine), PL and poly(L-glutamic acid) PGA were prepared from the laccase treated lignin to coat nanocellulose fibrils (CNF) with heat. NPs ca. 300 nm were prepared, β-casein coated and cross-linked with transglutaminase (Tgase) to agglutinate chamois specimens. Size exclusion chromatography (SEC) and Fourier-transform infrared (FTIR) spectroscopy were used to characterize polymerized lignin, zetapotential and dynamic light scattering (DLS) to ensure coating of colloidal lignin particles (CLPs). Protein adsorption on lignin was studied by quartz crystal microbalance (QCM). Atomic force microscopy (AFM) was exploited to examine interactions between different polymers and to image NPs with transmission electron microscopy (TEM). Tensile testing showed, when using CLPs for the adhesion, the stress improved ca. 10 and strain ca. 6 times compared to polymeric lignin. For the β-casein NPs the values were 20 and 8, respectively, and for the β-casein coated CLPs between these two cases. When NPs were dispersed in adhesive formulation, the Young's moduli confirmed significant improvement in the elasticity of the joints over the adhesive alone. Exploitation lignin in nanoparticulate morphology is a potential method to prepare bionanomaterials for advanced applications.
