“…2b), the presence of a weak SiH molecular band (A 2 Δ→X 2 Π at 414.2 nm) is observed. Such Si-based species are considered to be the plasma precursors for the formation of superhydrophobic CNC films (Matouk et al 2020).…”

“…Cho et al (2009) also reported a dramatic decrease of the wettability of filter paper surface after its exposure to low pressure HMDSO and toluene plasmas whereas Dimitrakellis et al (2017) obtained superhydrophobic paper by a double-step treatment consisting in surface etching followed by deposition of a thin fluorocarbon film. In addition, hydrophilic cellulose nanocrystals films were functionalized by appropriate plasma treatment to promote superhydrophilicity, hydrophobicity and superhydrophobicity surfaces by altering the plasma chemistry using different gaseous precursors (Matouk et al 2020). Natural lycopodium powder was exposed to plasma for changing its intrinsic wettability properties from hydrophobic to hydrophilic, thus allowing to obtain stable water suspension (Bormashenko and Grynyov 2012).…”

Despite promising characteristics such as the biodegradability and the environmentally-benign nature of cellulose nanocrystal (CNC) based composites, their poor dispersion and agglomeration in thermoplastic matrix during the melting process is a “bottleneck” in the development of these composites. In this work, a cylindrical atmospheric pressure dielectric barrier discharge (AP-DBD) was employed to functionalize CNCs to reduce their surface hydrophilicity and improve their dispersion in polar organic solvents. Three different gas mixtures were used for plasma treatment, argon/methane, argon/silane and an argon/methane followed by argon/silane. In all cases, the plasma treatment was conducted below 90°C as determined from optical emission spectroscopy (OES) analysis. The x-ray diffraction (XRD) analysis of both raw and plasma treated CNC powders confirms that the CNC crystallographic properties remain unchanged after plasma treatment. Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) analysis reveal the presence of hydrophobic C-Hx moieties on the CNC granular surface after argon/methane plasma treatment whereas SiHx, Si-O-Si, SiC bonds were formed after argon/silane plasma treatment. Under these experimental conditions, water wettability tests reveal some significant water repellency of the naturally hydrophilic cellulosic raw material. Moreover, the formation the SiHx moieties in silane-treated CNCs clearly enhances the hydrophobicity of the CNC powder in contrast to the sole C-Hx moieties synthetized by argon/methane plasma. High-resolution SEM images indicate the presence of agglomerated granules with 5-10 µm diameters in size. The surface functionalities of CNC powder enhance its dispersibility in polar solvents. Overall, this study emphasizes that AP-DBDs are suitable to process thermo-sensitive CNCs.

Nanocellulose and its derivatives represent the most abundant biopolymers on Earth, offering a wide range of advantages, including versatility in preparation, customizable functional group incorporation, and compatibility with various materials. They open up new horizons in the development of various types of metal‐ion batteries (MIBs). This work concisely categorizes nanocellulose design strategies, including rational isolation, surface chemical enhancement, and effective physical treatments. Subsequently, an overview of recent advancements in utilizing nanocellulose and its derivatives to enhance the performance of MIBs, from lithium‐ion batteries (LIBs) to post lithium‐ion batteries (e.g., Na+, K+, Zn2+, Mg2+, Ca2+) are provided. The pivotal roles of nanocellulose in electrode design, interface engineering, electrolyte modification, and binder optimization are highlighted. Lastly, the challenges and prospects of utilizing nanocellulose and its derivatives in MIBs are delved into. This work aims to comprehensively cover recent developments in nanocellulose surface modification strategies and illuminate their current applications in emerging MIBs with impressive energy and power densities.

Nanocellulose (NC) represents a pivotal material for the sustainable strategies of the future. NC comprises cellulose nanofibrils (CNFs), cellulose nanocrystals (CNCs), and bacterial nanocellulose (BNC), each exhibiting unique and exceptional physicochemical properties. These properties encompass high specific surface area, high tensile strength, lightweight, biodegradability, good barrier properties, and high processing versatility. However, the range of properties and applications can be significantly expanded through the modification of NC, involving both chemical and physical methodologies, which introduce a plethora
