Method for preparing material for directionally transmitting liquid

Abstract

The invention discloses a method for preparing a material for directionally transmitting liquid, which comprises the following steps: applying a placeholder on a hydrophilic material to form one or more regions containing the placeholder on the hydrophilic material; wherein the area containing the placeholder comprises a first surface and a second surface, and the content of the placeholder from the first surface to the second surface is in gradient change; subjecting the material to which the placeholder is applied to a hydrophobic treatment to obtain a material having one or more regions containing the placeholder and a hydrophobic region; and removing the placeholder to form one or more liquid transfer channels, thereby obtaining the material for directionally transferring the liquid. The method for preparing the material for directionally transmitting the liquid is simple to operate, the raw materials are easy to obtain, the material is very suitable for large-scale industrial application, and the prepared material for directionally transmitting the liquid can keep the capability of directionally transmitting the liquid for a long time and is durable. 本发明公开了一种制备制备定向传输液体的材料的方法，包括：通过在亲水性材料上施加占位剂，以在所述亲水性材料上形成一个或多个包含占位剂的区域；其中所述包含占位剂的区域包含第一表面和第二表面，从第一表面到第二表面的占位剂含量是梯度变化的；对施加了所述占位剂的材料进行疏水性处理，以得到具有一个或多个包含占位剂的区域和疏水性区域的材料；和去除占位剂以形成一个或多个液体传输通道，从而获得所述定向传输液体的材料。本发明制备定向传输液体的材料的方法操作简单，原料易得，非常适合大规模工业化应用，制备的定向传输液体的材料可长久的保持其定向传输液体的能力，经久耐用。
