Hydrophobic modification of wood membrane via dual silanes in aqueous system: Constructing efficient oil-water separation materials
Oil-water separation is a critical challenge in current environmental remediation and industrial production, urgently requiring the development of innovative materials with high efficiency, selectivity and sustainability. In this study, a facile aqueous media dual-silane modification approach is employed to functionalize the wood membrane, thereby preparing a hydrophobic FS-AS@Wood filter. The FS-AS@Wood achieves a stable water contact angle of 140° to 144°, which repels the water and selectively allows oil to pass through. FS-AS@Wood retains exceptional hydrophobicity even when subjected to mechanical and chemical damage, such as continuous sandpaper abrasion and exposure to strong acids and bases, while demonstrating self-cleaning properties. FS-AS@Wood exhibits excellent oil-water interface selectivity, achieving a separation efficiency of 97.8–98.5 % at a flux of 2000–2400 L m−2 h−1 when processing heavy oil-water mixtures, and maintaining high efficiency and stability even after 40 cyclic operations. For light oil-water mixtures, the adsorption capacity reaches 4–7 times its weight. This study shows that FS-AS@Wood is a promising material for treating oil contaminants from different fields.
期刊介绍:
Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
