Cellulose is the cheapest and mostly widespread green raw material on earth. Due to the easy and versatile developed modification of cellulose, many cellulosic paper-based sustainable materials and their multifunctional applications have attained increasing interest under the background of the implementation of the "plastic ban" policy. However, intrinsic cellulose paper is hydrophilic and non-water-proof, which highly limited its application, thus becoming a bottleneck for the development of "cellulosic paper-based plastic replacement". Unquestioningly, the superhydrophobic modification of cellulosic paper-based materials and the extension of their high value-added applications are highly desired, which is the main content of this review. More importantly, we presented the comprehensive discussion of the functionalized applications of superhydrophobic cellulosic paper-based materials ranging from conventional products to high value-added functional materials such as paper straw and paper mulch film for the first time, which have great industrialization potential and value. This review would offer the valuable guidance and insightful information for the rational construction of sustainable superhydrophobic cellulosic paper for advanced functional devices.
纤维素是地球上最便宜、分布最广泛的绿色原料。由于纤维素易于进行多种修饰，因此在实施“禁塑令”的背景下，许多基于纤维素的纸质可持续材料及其多功能应用引起了越来越多的关注。然而，天然纤维素纸是亲水性的，不防水，这极大地限制了其应用，因此成为“纤维素基塑料替代品”发展的瓶颈。毫无疑问，纤维素基材料的超疏水改性及其高附加值应用的拓展是人们所期望的，这也是本综述的主要内容。更重要的是，我们首次对超疏水纤维素基纸质材料的功能化应用进行了全面的讨论，这些应用涵盖了从传统产品到高附加值功能性材料（如纸吸管和纸地膜）的范围，具有巨大的工业化潜力和价值。本综述将为合理构建先进功能器件用可持续超疏水纤维素提供有价值的指导和有见地的信息。
