This study presents a novel hydrophobic lignocellulosic bioplastic from corn stover reinforced by oxidized cellulose and in situ regenerated lignin. Cellulose‐lignin mixture as a matrix was obtained by acid‐recyclable deep eutectic solvent (DES) pretreatment of corn stover in mild conditions. Triethoxy(octyl)silane (C14H32O3Si) was employed to improve the water stability of the bioplastic by vapor deposition. The results show that the hydrophobic bioplastic has a high tensile strength, measuring 62.36 MPa. The water contact angle of the bioplastic was increased from 8.50° to 121.9° after hydrophobic modification. We prepared oxidized cellulose‐reinforced cellulose paper by different particle size distributions of oxidized cellulose to investigate the reinforcement of oxidized cellulose. The tensile strength of oxidized cellulose cellulose paper increased from 14.41 to 21.18 MPa with the addition of oxidized cellulose. The zeta potential of oxidized cellulose is −47.99 mV, which shows a more negative charge due to carbonyl groups. The repulsive force of oxidized cellulose contributes to the formation of a brick‐and‐mortar microstructure with cellulose‐lignin mixture. It demonstrates that oxidized cellulose can act as bio‐adhesives and has a good toughening effect on the mechanical properties of bioplastic.Highlights Lignocellulosic bioplastic was prepared by DES pretreatment of corn stover.

“…Partial removal of noncellulosic components (i.e., lignin and hemicellulose) and the introduction of charged groups are considered as efficient chemical methods to achieve the defibrillation of recalcitrant wood cell wall structures . Several reactive DES systems have been used to fabricate nanostructured functional materials from lignocellulose resources based on bottom-up engineering strategies. − Reactive DES systems feature mild delamination of recalcitrant lignocellulose structures via a combination of hydrogen bond disruption, covalent bond hydrolysis, and charge group introduction. In this work, a reactive DES system comprising TEMACl, imidazole, and succinic anhydride, as the hydrogen-bond acceptor, hydrogen-bond donor, and reagent, respectively, was applied to achieve top-down engineering of natural wood toward the desired mesoporous hierarchical nanostructures for the first time.…”

The on-demand regulation of cell wall microstructures is crucial for developing wood as a functional building material for energy management and conversion. Here, a novel strategy based on reactive deep eutectic solvent is developed to one-step in situ fibrillate wood via disrupting the hydrogen bonding networks in cell walls and simultaneously carboxylating wood components, without significantly altering the native hierarchical structures of wood. Benefiting from its distinctive cell wall structure composed of individualized yet well-organized lignocellulose nanofibrils, in situ fibrillated wood exhibits a prominent mesoporous structure with a specific surface area of 81 m 2 /g. It represents a robust sponge material (5 MPa at 80% strain) with excellent durability. Due to the enhanced compressibility and charge polarization capacity, the in situ fibrillated wood (10 × 11 × 12 mm 3 ) can generate a piezoelectric output voltage of up to 2 V under 221 kPa stress. The favorable microstructural characteristics render in situ fibrillated wood with highly thermal-insulating properties, high solar reflectivity, and mid-infrared emissivity, favoring outdoor passive cooling effects with a subambient temperature drop of 6 °C. Combining its controllable, durable, and eco-friendly attributes, our developed wood sponge represents a versatile structural material suitable for indoor/outdoor energy-saving applications.

“…33 The versatile and tunable nature of DESs makes them effective for directional lignin valorization, creating opportunities for the development of novel DES-based solvent systems in future research. [34][35][36] Recent studies have also utilized DESs to construct biphasic systems for various applications. Chagnoleau et al intensively evaluated diverse combinations of DES-based organic biphasic systems from both theoretical and experimental perspectives for the purification of natural compounds.…”
