With increasing industrial oily wastewater and frequent oceanic spillage, advanced sorbent is highly demanded. Although the conventional sorbent with high specific surface area has good oil sorption capacity, its tortuous structure leads to liquid flow resistance. Inspired by wicking pathways of wood, we fabricated micron-scale aligned channel structure sorbent for fast wastewater treatment. The as-prepared sorbent was derived from delignified lignocellulosic biomass as a building block. Due to its abundant functional groups, micron-scale building blocks can assemble continuous oriented structure with intermolecular bonds. Furthermore, hydrolyzed methyltrimethoxysilane (MTMS) sol was formed hydrophobic coating layer via in-situ polysiloxane growth and provides mechanical robustness. Benefiting from these character, aligned channel structure sorbent showed fast oil contaminated water separation and good reusability with squeezing. |
