TL;DR: Rod-like straight cellulose whiskers and long flexible entangled microfibrillated cellulose (MFC) were used to prepare cellulosic membranes as discussed by the authors, and it was observed that the diffusion of water is rather controlled by the surface than by the core, probably because of a barrier effect related to the presence of water at the surface during the sorption kinetics.
322 citations
TL;DR: Both unmodified and chemically modified nanocrystals were used to prepare nanocomposites and their mechanical behavior was evaluated in both the linear and non-linear range.
129 citations
TL;DR: In this paper, the contribution of nanofiller content on the transport properties of poly(e-caprolactone) matrix was investigated through water sorption and water permeation processes, and its impact on the water transport properties was specifically investigated at a nanoparticle loading higher than percolation threshold.
116 citations
TL;DR: The findings revealed the size-dependent ingestion and accumulation of smaller MPs (0.45-3 µm) in fish tissues even after a short-term exposure, and that significant oxidative alterations were highly correlated with MPs size range.
67 citations
TL;DR: In this paper, a new thermo- and pH-sensitive block copolymers were prepared via reductive amination by end-to-end coupling reaction between the aldehyde function (reducing sugar) of pullulan with varied molar masses and the amine function of polyetheramine (i.e. methoxypoly (oxyethylene/oxypropylene)-2-propylamine) or PEO-PPO amine).

TL;DR: This review collocates current knowledge in the research and development of nanocelluloses and emphasizes more particularly on the chemical modification routes developed so far for their functionalization.
Abstract: Nanocelluloses, including nanocrystalline cellulose, nanofibrillated cellulose and bacterial cellulose nanofibers, have become fascinating building blocks for the design of new biomaterials. Derived from the must abundant and renewable biopolymer, they are drawing a tremendous level of attention, which certainly will continue to grow in the future driven by the sustainability trend. This growing interest is related to their unsurpassed quintessential physical and chemical properties. Yet, owing to their hydrophilic nature, their utilization is restricted to applications involving hydrophilic or polar media, which limits their exploitation. With the presence of a large number of chemical functionalities within their structure, these building blocks provide a unique platform for significant surface modification through various chemistries. These chemical modifications are prerequisite, sometimes unavoidable, to adapt the interfacial properties of nanocellulose substrates or adjust their hydrophilic–hydrophobic balance. Therefore, various chemistries have been developed aiming to surface-modify these nano-sized substrates in order to confer to them specific properties, extending therefore their use to highly sophisticated applications. This review collocates current knowledge in the research and development of nanocelluloses and emphasizes more particularly on the chemical modification routes developed so far for their functionalization.

TL;DR: A review of cellulose chemically extracted nanocrystals can be found in this article, where the authors provide an overview about several aspects that involve this material, including sources, properties, challenges, and perspectives.
Abstract: Cellulosic nanoparticles with high Young's modu- lus, crystallinity, specific surface area, and aspect ratio can be found in the natural structure of plant fibers. Indeed, lignocel- lulosic fibers consist of semicrystalline cellulose nanofibrils embedded in an amorphous matrix mainly composed of lignin and hemicelluloses. These nanostructures give the mechanical strength to higher plant cells, and are biodegradable, renew- able, resistant, and widely available to produce nanocompo- sites with low density, and improved and controlled mechanical, optical, and barrier properties. Nanoparticles can be extracted from cellulose using a top-down mechanically or chemically assisted deconstructing strategy, and owing to their highly reactive surface ensuing nanomaterials can be chemi- cally modified to tailor their properties for a wide range of applications. This review is limited to cellulose chemically extracted nanocrystals and aims to provide an overview about several aspects that involve this material, including sources, properties, challenges, and perspectives.
