However, these highly textured surfaces (micro/nanotextured)suffer from frequent liquid penetration in high humidity and abrasion-induceddestruction of the local environment. Herein, bioinspired superhydrophobicfibrous materials are reviewed from the perspective of the dimension scale offibers. First, the fibrous dimension characteristics of several representativenatural superhydrophobic fibrous systems are summarized, along with themechanisms involved. Then, artificial superhydrophobic fibers aresummarized, along with their various applications. Nanometer-scale fibersenable superhydrophobicity by minimizing the liquid–solid contact area.Micrometer-scale fibers are advantageous for enhancing the mechanicalstability of superhydrophobicity. Micrometer-scale conical fibrous structuresendow a Laplace force with a particular magnitude for self-removingcondensed tiny dewdrops in highly humid air and stably trapping large airpockets underwater. Furthermore, several representative surface modificationstrategies for constructing superhydrophobic fibers are presented. In addition,several conventional applications of superhydrophobic systems arepresented. It is anticipated that the review will inspire the design andfabrication of superhydrophobic fibrous systems. 收起
