摘要：随着水体油类污染造成的环境和健康危害问题日益严重,开发高效、低成本且绿色环保的油水分离材料受到越来越多的关注。木材作为一种可持续、可再生、可生物降解的环境友好型天然材料,具有多尺度分级结构、高度各向异性、丰富的孔隙构造以及结构可调控等特点。直接利用木材的层级多孔结构,通过“自上而下”策略对木材的化学组成、孔隙结构以及表面润湿性进行调控,可为开发高性能油水分离材料提供新思路和新方法。本文从过滤和吸附两种主要的油水分离方式出发,介绍近年来基于天然木材的多孔过滤膜和吸油材料的构建策略,并综述这两类木基功能材料用于分离不混溶油水混合物、油水乳液和水面高黏度原油的最新研究进展,讨论存在的问题以及未来潜在的研究方向。
With the increasingly serious environmental pollution and health hazards caused by oil contaminated water,the development of high-efficiency,low-cost,and green oil/water separation materials has attracted more and more attention.As a sustainable,renewable,and biodegradable environment-friendly natural material,wood possesses many advantageous features such as multi-scale hierarchical structure,high anisotropy,abundant pore structure,and diverse tunability.Taking advantage of its hierarchical porous structure directly,wood can be deliberately tuned in terms of its chemical composition,pore structure,and surface wettability through the"top-down"strategy,which can provide new ideas and methods for the development of high-performance oil/water separation materials.In this review,based on the two main oil-water separation methods of filtration and adsorption,the strategies for constructing wood-derived porous filter membranes and oil-absorbing materials in recent years are introduced.The latest research progress is summarized in using these two kinds of wood-based functional materials for separating immiscible oil/water mixtures,oil-water emulsions,and high-viscosity crude oils on water surface.In addition,the existing problems in the research of the wood-based porous oil/water separation materials and the perspectives of the future research direction are also discussed.
