Narrow and tortuous interstitial paths through parallelly oriented interlayer spacings hinder the practical viability of 2D laminar membranes due to the limited membrane permeance. Ubiquitous stress involved wrinkling morphologies of biological tissues inspire us to exploit spontaneously formed wrinkles for facilitating transmembrane molecular transport. Herein, a stress driven wrinkle engineering methodology is proposed for manipulating micron- and nano-scale wrinkles as a new class of transport pathways of GO membranes. Micron-scale wrinkles of GO laminates are initiated by capillary stress via good solvents evaporation, while nano-scale wrinkles of GO nanosheets are induced by entropy stress via poor solvents resolvation. The deliberately tailored GO membranes possess nanoarchitectures with both high porous volume and low defective degree, thus achieving remarkable molecular separation performances (water permeance of ∼69.2 L m⁻² h⁻¹ bar⁻¹and dye rejection of >98%). This work offers a straightforward experimental strategy for designing high-performance 2D laminar membranes via rational wrinkle manipulations.

由于有限的膜渗透性，通过平行取向的层间距的狭窄和曲折的间隙路径阻碍了二维层状膜的实际可行性。无处不在的压力涉及生物组织的皱纹形态，这激发了我们利用自发形成的皱纹来促进跨膜分子转运。在此，提出了一种应力驱动的皱纹工程方法，用于操纵微米级和纳米级皱纹，作为 GO 膜的一类新的运输途径。GO 层压板的微米级皱纹是由毛细管应力通过良溶剂蒸发引起的，而 GO 纳米片的纳米级皱纹是由熵应力通过溶解不良的溶剂。精心设计的 GO 膜具有高孔体积和低缺陷度的纳米结构，从而实现了显着的分子分离性能（~69.2 L m ^-2  h ^-1 bar ^-1的水渗透性和 >98% 的染料截留率）。这项工作为通过合理的皱纹操作设计高性能二维层状膜提供了一种直接的实验策略。
