“…Because of their very high water affinity coupled with large surface-to-volume ratios, nanocelluloses form self-sustained gels with as little as 2% solid and find applications in many fields [ 6 ]. Apart from the obvious possibility of remodeling the current food packaging scenario by taking advantage of the outstanding properties of nanocelluloses [ 34 ], recent contributions demonstrate that they appear as favorable candidates for the design of hydrogels and cryogels [ 35 ], including those that exhibit electric conductive properties [ 36 ], of gas barrier [ 37 ] and membrane filtration materials [ 38 ], of supercapacitors [ 33 ], of photoremediation agents for contaminated environments [ 39 ], of oil and gas production green additives, especially in enhanced oil recovery and hydraulic fracturing applications [ 40 ], and of novel biomedical systems, as for targeted chemo-protodynamic/photothermal cancer therapy [ 41 ]. Other common applications involve nanocelluloses as paper additives, implants, dentistry aids and cosmetics, and reinforcing elements in composite materials [ 42 ].…”

A progressively increasing concern about the environmental impacts of the whole polymer industry has boosted the design of less aggressive technologies that allow for the maximum use of carbon atoms, and reduced dependence on the fossil platform. Progresses related to the former approach are mostly based on the concept of the circular economy, which aims at a thorough use of raw materials, from production to disposal. The latter, however, has been considered a priority nowadays, as short-term biological processes can efficiently provide a myriad of chemicals for the polymer industry. Polymers from renewable resources are widely established in research and technology facilities from all over the world, and a broader consolidation of such materials is expected in a near future. Herein, an up-to-date overview of the most recent and relevant contributions dedicated to the production of monomers and polymers from biomass is presented. We provide some basic issues related to the preparation of polymers from renewable resources to discuss ongoing strategies that can be used to achieve original polymers and systems thereof.

“…Nanocellulose is attractive as an alternative material for PEMs due to its intrinsic properties, such as high mechanical strength [ 14 ], exceptional gas barrier properties [ 15 ], acidic functional groups leading to proton conductivity [ 16 ], and a polymer structure suitable for various chemical modifications. As a biodegradable polymer, it has an additional advantage over the fluorinated PEMs and hydrocarbon PEMs, such as Nafion ® , in terms of sustainability and the circular economy.…”

Nanocellulose is a sustainable material which holds promise for many energy-related applications. Here, nanocrystalline cellulose is used to prepare proton exchange membranes (PEMs). Normally, this nanomaterial is highly dispersible in water, preventing its use as an ionomer in many electrochemical applications. To solve this, we utilized a sulfonic acid crosslinker to simultaneously improve the mechanical robustness, water-stability, and proton conductivity (by introducing -SO3−H+ functional groups). The optimization of the proportion of crosslinker used and the crosslinking reaction time resulted in enhanced proton conductivity up to 15 mS/cm (in the fully hydrated state, at 120 °C). Considering the many advantages, we believe that nanocellulose can act as a sustainable and low-cost alternative to conventional, ecologically problematic, perfluorosulfonic acid ionomers for applications in, e. fuel cells and electrolyzers.

“…It is even suggested that high CO 2 permeability is preferred over high CO 2 /N 2 selectivity. 11 Despite the impressive enhancement in gas transport property under humid conditions, the CO 2 permeability of neat nanocellulose is still not high enough for the flue gas purification. To further raise CO 2 permeability, nanocellulose has been blended with polymers, especially hydrophilic ones.…”

“…Nanocellulose, as a representative biomaterial, attracted researchers’ attention due to its unique properties (e.g., remarkably high mechanical properties, excellent surface area, and a great number of hydroxyl groups available for functionalization). , Although nanocellulose is well known for its gas-barrier property (that is, impermeable for gas and water vapor) due to its crystalline nature, recently, researchers have noticed that the gas transport in nanocellulose is actually greatly affected by the test conditions and the type of nanocellulose. For example, the CO 2 permeability of a self-standing nanocellulose fiber (CNF) membrane is around 0.04 Barrer under ambinet dry conditions .…”

Developing a membrane material with both high CO2 permeability and high CO2/N2 selectivity is always desired for CO2 capture, while improving the sustainability of the membrane preparation process is of equal importance. In the current work, a nanocellulose crystal (CNC) was blended with hydrophilic Pebax 1657 for CO2 separation application. The CO2/N2 separation performance of Pebax 1657/CNC hybrid membranes with up to 40 wt % CNC was evaluated by mixed-gas permeation tests under both dry and humid conditions. The humid test condition simultaneously increases CO2 permeability and CO2/N2 selectivity of all CNC/Pebax hybrid membranes compared to those under dry conditions. Introduction of only 5 wt % CNC into Pebax 1657 realizes 42 and 18% increments in CO2 permeability (305.7 Barrer) and CO2/N2 selectivity (41.6), respectively. However, further increasing the CNC loading increases the tortuosity of the membrane and results in the self-assembly of CNC in the Pebax matrix, which is observed by SEM, thus leading to both reduced gas permeability and CO2/N2 selectivity. The CO2/N2 separation results of 5 wt % CNC/Pebax locate close to Upper Bound 2008, showing its potential as a CO2/N2 separation membrane material.
