摘要：多孔材料的合成与调控在材料科学、能源科学等领域有着迫切的研究和应用需求,然而其制备的过程存在能耗高、不环保等问题。因此,绿色可持续多孔材料的开发与利用亟待研究。木材是一种天然多孔材料,具有可持续、可降解、易修饰等特点,细胞腔、纹孔、细胞壁中的孔隙、微纤丝间隙等大小不同的孔隙构成了木材层级多孔结构。但木材孔隙结构分布不均匀、孔隙类型相对固定,为实现更广泛的功能化应用,需要对木材孔隙结构进行调控。通过对木材孔隙的大小、形状、数量和联通性等进行调控,不仅可以改善木材原本的理化性能,还可以赋予其新的功能。分别从物理、化学、生物等层面总结木材孔隙结构的调控手段及其调控后材料在建筑、环境、能源、输导、智能器件等领域的应用,并展望木材孔隙结构调控的发展趋势,以期挖掘木材作为多孔材料的更大潜力,为木基多孔新材料的发展提供理论支撑与技术支持。
The research on the synthesis and regulation of porous materials has gained significant interests in fields such as materials science,life science,and energy science.However,the synthesis process faces challenges such as high energy consumption and environmental friendliness.The development and utilization of green and sustainable porous materials urgently need to be studied.Wood is a natural porous material,which is sustainable,biodegradable,and easy to modify.The hierarchical porous structure is constituted of pores of different sizes such as cell lumen,pits,pores in the cell wall and inter-microfibril spaces.Nevertheless,as a porous material,the distribution of wood porous structure is uneven,and the pore type is relatively fixed.In order to achieve a wide range of applications,the pore structure need to be regulated.By regulating the size,shape,quantity,and connectivity of the pores,not only can the original physical properties of wood be improved,but also new functions can be given to it.In this review,we summarize the regulation methods for the porous structure of wood and the applications of modified wood in building materials,environment,and biological aspects respectively.Finally,the development trend of wood pore structure regulation is prospected to exploit the great potential of wood as a porous material and provide theoretical and technical support for the development of wood-based porous new materials.
