Dramatic volume changes of silicon anode materials lead to the pulverization and shedding of active materials, which hinders their further practical application. Silicon binders can greatly relieve the volumetric expansion issue and improve the cycle life. Herein, a natural three-dimensional cross-linked biopolymer gum, Sa-son seed gum (SG), is modified by carboxymethylation and applied to silicon anodes as a binder to implement long-term stable cycling. The modified Sa-son seed gum (CMSG) provides a strong interfacial binding force with silicon particles to adapt to the volume change due to their rich carboxyl and hydroxyl groups. Meanwhile, the introduction of the carboxymethyl group of the binder increases the water solubility resulting in a feasible process for a uniform electrode. The CMSG binder exhibits high mechanical strength and long-lasting interfacial adhesivity to stabilize the electrode integrity of silicon anodes. The Si@CMSG electrode shows a high initial Coulombic efficiency (ICE) of 89.67% and a reversible capacity of 2060 mAh/g after 240 cycles at a current density of 0.84 A/g. Furthermore, electrochemical impedance spectroscopy (EIS) indicates that the CMSG binder can effectively reduce interfacial impedance, increase the ion diffusion rate, and reduce electrode polarization.

“…36 Fourier transform infrared spectroscopy (FTIR) analysis was conducted to assess the reduction of lignin in cellulose following the delignification process with a scan between 600–4000 cm −1 . 37 Scanning electron microscopy (SEM) with an attached Energy Dispersive X-ray spectrometer (EDS) was employed to visualize the morphology of both untreated and treated oil palm empty fruit bunch (OPEFB) samples and detect any elemental distribution on the corn starch surface. 38 These analytical techniques provide valuable insights into the chemical composition, structure, and surface properties of cellulose and its derivatives, aiding in the characterization and evaluation of cellulose-based materials.…”

This investigation was centered on the intricate processes of fabricating and fine–tuning the concentration of microcellulose derived from oil palm empty fruit bunch (OPEFB). The objective was to employ it as a reinforcing agent, with sorbitol serving as a plasticizer, and chitosan acting as both a plasticizer and a strengthening agent for the formulation of bioplastic films to gain higher value mechanically. The cellulose extraction involved a methodical delignification approach, extracting lignin and hemicellulose from OPEFB to yield brown pulp. Subsequent double peroxide bleaching was employed to reduce the lignin concentration in the pulp. Leveraging the Box–Behnken experimental within a response surface methodology framework, the study scrutinized the influence of independent parameters (additive concentrations) on the ultimate tensile strength and Young’s modulus of the fabricated bioplastic films. Noteworthy variations in ultimate tensile strength and Young’s modulus were discerned, underscoring the impact of microparticle loading on the mechanical attributes of the bioplastic films. The quadratic polynomial model derived from experimental data exhibited coefficients of determination (R2) of 0.8690 for ultimate tensile strength and 0.6793 for Young’s modulus, affirming the adeptness of the models in navigating the optimization space. Microcellulose was isolated (30 – 40) wt.% of OPEFB as the white pulp which revealed a homogenous dispersion with chitosan in the corn starch matrix. The superior tensile strength and Young’s modulus were observed at 6.84 MPa and 21.94 MPa respectively.

Transparent paper manufactured from wood fibers is emerging as a promising, cost‐effective, and carbon‐neutral alternatives to plastics. However, fully exploring their mechanical properties is one of the most pressing challenges. In this work, a strong yet tough transparent paper with superior folding endurance is prepared by rationally altering the native fiber structure. Microwave‐assisted choline chloride/lactic acid deep eutectic solvent (DES) pulping is first utilized to isolate wood fibers from spruce wood. During this process, the S1 layer within the fibers is partially disrupted, forming protruding microfibrils that play a crucial role in enhancing cellulose accessibility. Subsequently, carboxymethylation treatment is applied to yield uniformly swollen carboxymethylated wood fibers (CM fibers), which improves the interaction between CM fibers during papermaking. The as‐prepared transparent paper not only shows a 90% light transmittance (550 nm) but also exhibits impressive mechanical properties, including a folding endurance of over 26 000, a tensile strength of 248.4 MPa, and a toughness of 15.6 MJ m−3. This work provides a promising route for manufacturing transparent paper with superior mechanical properties from wood fibers and can extend their use in areas normally dominated by high‐performance nonrenewable plastics.
