We review the recent research on structure-induced water collecting properties of spider silk and bioinspired fibers. Since the capture silks of cribellate spiders have a unique wet-rebuilt structure with spindle-knots and joints for directional water collection, we were inspired to fabricate a series of artificial gradient micro-/nanostructure fibers. These fibers display excellent functions, such as driving tiny water drops in certain directions, water capturing, multi-gradient cooperation effect, and wet-response to environmental humidity. This review is helpful to the design of novel smart functional materials that can be extended to develop devices or systems for water collection, sensors, fluid-control, filters and others.
我们综述了近年来关于蜘蛛丝和仿生纤维的结构诱导集水性能的研究。由于具纺器蜘蛛的捕获丝具有独特的湿重建结构，带有纺锤结和关节，可定向集水，因此我们受到启发，制造了一系列人工梯度微/纳米结构纤维。这些纤维具有优异的功能，例如驱动微小水滴沿特定方向运动、集水、多梯度协同效应以及对环境湿度的湿响应。本综述有助于设计新型智能功能材料，可进一步开发用于集水、传感器、流体控制、过滤等的器件或系统。
