摘要:纤维素是一种来源广泛的生物质基材料，由于其生物相容性好、分子结构中的羟基丰富、密度低等性质而用于食品、医药、化学品等领域，备受科研工作者关注。近年来，对纤维素进行疏水化改性的研究使其应用范围进一步拓宽。本文从纤维素构建超疏水材料的表面能物质、含微/纳粗糙结构的表面构造等方面进行了综述，并归纳了该类超疏水材料在油水分离、高效吸附、集水等领域的应用。

Abstract:Cellulose is a kind of biomass based materials with a wide range of sources， which is used in food， medicine， chemicals， and other fields due to its good biocompatibility， abundant hydroxyl groups in molecular structure， and low density. In recent years， the research on hydrophobic modification of cellulose has further broadened its application scope. In this paper， the surface energy materials and the surface structures containing micro/nano rough structures of cellulose-based superhydrophobic materials are reviewed， and the potential applications of superhydrophobic materials in oil-water separation， efficient adsorption， water collection， and other fields are summarized.
