“…S1 †). Recently, Jankowska et al showed that lms made of nanocellulose had higher proton conductivity compared to the ones made of larger microcellulose, 24 supporting our results that highlight the importance of high aspect ratio nanobers and well dened and homogenous membrane structures (achievable by controlled slow drying conditions). Aer the fuel cell evaluation, the physicochemical characterization (including SAXS, XRD and IR) show no signicant alteration in their chemistry, crystallinity or microstructure (see ESI, Fig.…”

“…In this regard, thanks to their chemical stability, advantageous mechanical and optical properties, environmental benignity, availability and versatility in the manufactory process, 16,17 the use of cellulose nanomaterials in energy applications such as lithium ion batteries [18][19][20][21][22] and PEMFC itself 23,24 has increased dramatically in recent years. [25][26][27] Several different types of nanocelluloses 16 have been investigated in PEMFCs: bacterial cellulose (BC) membranes have shown a low conductivity z 0.008 mS cm À1 at 40 C and 98% RH.…”

“…28 Bayer et al studied carboxylated cellulose nanobers (CNF) and cellulose nanocrystals (CNC) membranes as PEM for high temperature application and obtained a slightly higher performance characterized by a maximum conductivity value at 100% RH of 0.05 mS cm À1 (100 C) and 0.01 mS cm À1 (30 C) using an ex situ measurement replicating the fuel cell environment. 23 Jankowska et al 24 compared the performance of several nano-and microcelluloses and observed a maximum proton conductivity of z0.001 mS cm À1 at 90 C under non-controlled RH conditions. The reported values clearly show that the proton conductivity is still below that of Naon and similar alternatives by orders of magnitude.…”

“…The study showed that the composites with the incorporation of CNF presented a better thermal stability than the CNC/soy protein isolate nanocomposites. The lower thermal stability of CNC‐incorporated composites could be attributed to the high surface area of CNC, which led to a larger exposure to heat and the partial disruption in the cellulose crystal structure …”

Nanocellulose has received increasing attention in science and industry in recent years as a nanoscale material for the reinforcement of polymer matrix composites due to its superior mechanical properties, renewability, and biodegradability. New nanocellulose sources, modifications, and treatments are under development to reduce the high energy required during production and to create a more suitable industrial-scale production process. Thus, this paper reviews plant-based nanocellulose composites and their properties, with a focus on their thermal-related characteristics. The purpose of this review is to establish for readers the impact of the incorporation of nanocellulose on the thermal and dynamic mechanical properties of nanocellulose composites. Understanding of the thermal properties is important for researchers to assess the suitability of the nanocomposites for a variety of applications in response to new and evolving societal requirements.The first NFC was produced from wood by using high-pressure homogenization without any pretreatment. 11,12 However, this method is a very energy-intensive process. Therefore, chemical treatments such as 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidation combined with mechanical and chemical

Cellulose is derived from biomass and is useful in a wide range of applications across society, most notably in paper and cardboard. Nanocellulose is a relatively newly discovered variant of cellulose with much smaller fibril size, leading to unique properties such as high mechanical strength. Meanwhile, electrochemical energy conversion in fuel cells will be a key technology in the development of the hydrogen economy, but new lower cost proton exchange membrane (PEM) materials are needed. Nanocellulose has emerged as a potential candidate for this important application. In this review we summarize scientific developments in the area of cellulosic materials with special emphasis on the proton conductivity, which is the most important parameter for application in PEMs. We cover conventional cellulose and nanostructured cellulose materials, polymer composites or blends, and chemically modified cellulose. These developments are critically reviewed, and we identify interesting trends in the literature data. Finally, we speculate on future directions for this field.
