The present study aims to investigate the structure–morphology–rheology relationships for cellulose nanoparticles (CNPs), including nanofibers (CNFs) and nanocrystals (CNCs). CNCs were extracted from never dried CNFs using sulfuric acid with controlled hydrolysis time. crystalline structure, surface charge, morphology, rheological behavior of CNPs measured contrasted. CNF suspensions exhibited rigid solid-like viscoelastic even at a low concentration due formation highly entangled network....
Rheological and filtration characteristics of drilling fluids are considered as two critical aspects to ensure the success a operation. This research demonstrates effectiveness cellulose nanoparticles (CNPs), including microfibrillated (MFC) nanocrystals (CNCs) in enhancing rheological performances bentonite (BT) water-based (WDFs). CNCs were isolated from MFC through sulfuric acid hydrolysis. In comparison with MFC, resultant had much smaller dimensions, more negative surface charge, higher...
This research aims to develop low cost, sustainable, environmentally friendly, and high performance water-based drilling fluids (WDFs) using bentonite (BT), polyanionic cellulose (PAC), nanocrystals (CNCs). The effect of concentration BT, PAC, CNCs on the rheological filtration properties PAC/CNC/BT-WDFs was investigated. Eight empirical models were applied fit quantitatively fluid properties. Results showed that presence CNCs, BT improved WDFs. Among eight models, Sisko model performed best...
Abstract Direct ink writing technology is capable of using 2D MXene to construct 3D architectures for electrochemical energy storage (EES) devices that are normally difficult achieve conventional techniques. However, meet specific rheological requirements printing, a large amount needed in the ink, resulting severe self‐restacking structure after drying. Herein, series cellulose nanofibers (CNFs) with different morphologies and surface chemistries applied enhance rheology MXene‐based inks...
Abstract Conventional self‐charging systems are generally complicated and highly reliant on the availability of energy sources. Herein, a chemically self‐charging, flexible solid‐state zinc ion battery (ssZIB) based vanadium dioxide (VO 2 ) cathode polyacrylamide‐chitin nanofiber (PAM‐ChNF) hydrogel electrolyte is developed. With power density 139.0 W kg ‐1 , ssZIBs can deliver high 231.9 Wh . The superior electrochemical performance attributed to robust tunnel structure VO entangled network...
Abstract Uncontrollable zinc dendrite growth and parasitic reactions have greatly hindered the development of high energy long life rechargeable aqueous zinc‐ion batteries. Herein, synergic effect a bifunctional lignin‐containing cellulose nanofiber (LCNF)‐MXene (LM) layer to stabilize interface anode is reported. On one hand, LCNF provides enough strength (43.7 MPa) at relative low porosity (52.2%) enable diffusion limited suppression, while, on other MXene serves as gating layer,...
The 3D printing technique offers huge opportunities for customized thick-electrode designs with high loading densities to enhance the area capacity in a limited space. However, key challenges remain formulating printable inks exceptional rheological performance and facilitating electronic/ion transport thick bulk electrodes. Herein, hybrid ink consisting of woody-derived cellulose nanofibers (CNFs), multiwalled carbon nanotubes (MWCNTs), urea is formulated nitrogen-doped electrodes, which...

ABSTRACT In this study, redox‐initiated free radical graft copolymerization of microcrystalline cellulose (MCC) and methyl methacrylate (MMA) has been carried out in aqueous media to develop a novel cellulose‐based copolymer. Cerium ammonium nitrate was used as the initiator presence nitric acid. Effects monomer concentration, polymerization time, temperature on parameters copolymers were studied. The successful grafting between MCC MMA validated through attenuated total reflection,...

Poly (vinyl pyrrolidone) (PVP)/cellulose nanocrystal (CNC)/silver nanoparticle composite fibers were prepared via electrospinning using N,N′-dimethylformamide (DMF) as a solvent. Rheology, morphology, thermal properties, mechanical and antimicrobial activity of nanocomposites characterized function material composition.
