“…To improve the separation performance of PPMs, scientists have devoted intensive efforts to the modulation of pore diameter, porosity, pore diameter distribution, surface functionalization, as well as the fabrication strategy of composite membranes. 10,[13][14][15][16][17] However, compared to other parameters, little attention has been paid to the effects of pore/channel tortuosity. For example, Eykens et al provided a comprehensive overview of the optimal membrane properties including wettability, pore diameter, membrane thickness, porosity, pore tortuosity, and thermal conductivity.…”

Membrane separation technology plays a pivotal role in modern industry and scientific research. The key to developing and improving membrane separation processes lies in designing and fabricating customized porous membranes with specific physical parameters, including pore diameter, porosity, pore size distribution, pore length (membrane thickness), pore geometry, and pore connectivity. Polymeric porous membranes with vertically‐penetrative‐pores (PPMVs) represent a distinct category among the available membranes due to their unique characteristics such as short transport path, small trans‐membrane resistance, and simple pore geometry, as compared to other porous membranes with sponge‐like channels. In practical applications, PPMVs offer several advantages, including achieving higher flux rates, facilitating easier unidirectional transport, and enabling harmless biological extraction. Moreover, PPMVs can serve as ideal model systems for theoretical investigations on the fundamental mechanisms of separation and transport in academic research. With substantial advancements in fabrication technologies and application fields of PPMVs in recent years, it warrants a comprehensive perspective. In this mini‐review, we provide an overview of widely used fabrication methods for PPMVs, discuss their primary applications, and address the existing challenges and opportunities.

Spontaneous or non‐spontaneous unidirectional fluid transport across multi‐dimension can occur under specific structural designs and ambient elements for porous materials. While existing reviews have extensively summarized unidirectional fluid transport on surfaces, there is an absence of literature summarizing fluid's unidirectional transport across porous materials. This review introduces wetting phenomena observed on natural biological surfaces or porous structures. Subsequently, it offers an overview of diverse principles and potential applications in this field, emphasizing various physical and chemical structural designs (surface energy, capillary size, topographic curvature) and ambient elements (underwater, under oil, pressure and solar energy). Applications encompass moisture‐wicking fabric, sensors, skincare, fog collection, oil‐water separation, electrochemistry, liquid‐based gating, and solar evaporators. Additionally, we have compiled significant principles and formulas from various studies to offer readers valuable references. Simultaneously, we critically assess potential advantages and challenges in these applications and present our perspectives.This article is protected by copyright. All rights reserved
