Controllable liquid transport material and system, and method for preparing controllable liquid transport material

Abstract

A controllable liquid transport material, a controllable liquid transport system, and a method for preparing a controllable liquid transport material. A first region of the controllable liquid transport material is treated to be hydrophobic, while a plurality of second regions, which have different shapes and are in partial contact or are completely separated, are treated to have gradients or different wettabilities and/or pore sizes which are used for performing passively controllable liquid transport, and/or are combined with an intelligent material which is used for performing actively controllable liquid transport which is driven by an external force, thereby allowing for efficient and controllable directional transport of a liquid such as sweat. The controllable liquid transmission system comprises a controllable liquid transport material which is used as a liquid transport layer, and a ventilating and waterproof protective layer. 本发明涉及一种可控液体传输材料，其中该材料的第一区域被处理为具有疏水性，而具有不同形状的局部接触或完全分开的多个第二区域则被处理为具有用于被动可控液体传输的梯度或不同润湿性和/或孔径，和/或与用于由外力(诸如电渗力或超声波震荡)驱动的主动可控液体传输的智能材料结合，从而允许液体例如汗液的有效且可控的定向传输，阻挡外部液体，减少粘着，并且保持透气和干爽。本发明还涉及一种可控液体传输系统，其包括本发明所述的可控液体传输材料作为液体传输层以及透气、防水的防护层。本发明还涉及制备本发明所述可控液体传输材料的方法。
