Materials Horizons, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 1, 2025

In recent years, the widespread use of wood products has been observed in many fields. Wooden have excellent green and environmentally friendly characteristics, but their performance often cannot meet people's needs. Many researchers conducted in-depth research on wood-based composite materials modification methods order to improve wood. This article provides a selective review types, methods, properties inorganic modifiers. The preparation are mainly divided into immersion sol-gel hydrothermal synthesis. flame retardancy, mechanical properties, hydrophobicity, mold resistance modified effectively improved. addition, also photoresponsive electrical conductivity, thermal conductivity. Finally, challenges perspectives advanced wood-inorganic composites proposed for guiding future studies.

Compatibilization and reinforcement of highly filled wood flour/polyethylene composites via peroxide‐induced grafting and crosslinking

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Abstract The industrialized development of biocomposites effectively promotes the high‐value utilization waste biomass resources, generating substantial economic benefits. However, in highly filled systems (≥50 wt.%), wood flour agglomeration and poor interfacial compatibility between components significantly degrade performance final biocomposites, thus restricting their applications. In this work, we developed a low‐maleic anhydride grafted microcrosslinking polyethylene matrices specialized for (50–70 wt.%) enhancing mechanical properties. successful grafting maleic (MAH) onto molecular chains formation crosslinked structure were evidenced by characteristic infrared absorption peak at 1792 cm −1 new torque peak. Grafting matrix with MAH enhanced adhesion matrix, as well dispersion within matrix. Adding small amount peroxide (0.09 improved tensile, flexural, impact strengths composites up to 120%, 125%, 209%, respectively, compared unmodified composites. This study proposes simple cost‐effective method low modification innovative application system yields significant results expands applications construction materials. Highlights Matrix enhances compatibility. Initiator‐induced crosslinking plastic deformation. properties Fine particles enhance energy

Bioinspired Lignocellulose Foam: Exceptional Toughness and Thermal Insulation

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

The biofoam exhibits significant advantages in environmental and sustainability aspects as an effective alternative to petrochemical foams; however, its limited mechanical stability seriously hinders practical application. Herein, a synergistic strategy combining structural bionics supramolecular cross-linking is proposed fabricate biodegradable lignocellulosic featuring "pillar-spacer" microlattice texture, utilizing multiscale cellulose fibers (CFs) sodium lignin sulfonate (SLS) inspiration from the natural cuttlebone. Attributed robust interfacial bonding between nanoscale SLS, akin "rebar cement", complemented by support microfibers, CFs/SLS with low density of 62 mg cm-3 compression modulus 6.56 MPa, nearly four times higher than that CF (1.67 MPa). Additionally, it excellent thermal insulation, boasting remarkably conductivity 0.046 W m-1 K-1, outperforming recently reported biofoams plastic foams. Moreover, integrating functional SiO2 nanocoating results SiO2@CFs/SLS foam, which delivers satisfactory flame retardation smoke inhibition without compromising strength or insulation. This work highlights potential for developing sustainable, eco-friendly, mechanically applications.
