“…Therefore, to further explore the formation mechanism of the nanofibrous cellular grid structure, electric field simulation of the electrospinning process was performed by COMSOL Multiphysics (Supplementary Methods). 31,32 Taking a double-cross configuration at the intersections of copper wires as the basic unit, the model of the receiving substrate was established (Figure S2). Figure 2e shows the electric field distribution on the y−z-plane.…”

Harvesting water from untapped fog is a potential and sustainable solution to freshwater shortages. However, designing high-efficiency fog collectors is still a critical and challenging task. Herein, learning from the unique microstructures and functionalities of the Namib desert beetle, honeycomb, and pitcher plant, we present a multi-bioinspired patterned fog collector with hydrophilic nanofibrous bumps and a hydrophobic slippery substrate for spontaneous and efficient fog collection. Interestingly, hydrophilic nanofibrous bumps display a honeycomb-like cellular grid structure self-assembled from electrospun nanofibers. Notably, the patterned nanofibrous fog collector exhibits superior watercollecting efficiency of 1111 mg cm −2 h −1 . The hydrophilic nanofibrous bumps increase the effective fog-collecting area, and the hydrophobic slippery substrate promotes quick transport of collected water in the desired direction reducing the secondary water evaporation, finally achieving rapid directional transport of tiny droplets and high-efficiency water collection. This work opens a new avenue to collect water efficiently and provides clues to research on the multi-bioinspired synergistical optimization strategy.

Freshwater shortage is a critical global issue that needs to be resolved urgently. Efficient water collection from fog provides a promising and sustainable solution to produce clean drinking water, especially in the desert and arid regions. Nature has long served as our best source of inspiration for designing new structures and developing new materials. Herein, we report a strategy to design a novel Janus fog collector with a hydrophilic lizard-skin-like nanofibrous network upper surface and hydrophobic slippery lower surface using a simple and feasible method of coating and electrospinning. We analyze the forming law of the lizard-skin-like nanofibrous network structure on different substrates using electric field simulation. The resulting copper mesh-based Janus fog collector exhibits superior water-collecting efficiency (907 mg cm–2 h–1) and long-term durability, achieving directional transport of tiny droplets and high-efficiency water collection. However, there are few reports on the combination of the lizard-skin-like nanofibrous capillary network and slippery surface for efficient fog collection. Therefore, we believe that this work will open a new avenue to collect water efficiently and also provide clues to research on the lizard-skin-like nanofibrous network structure.

“…Since the fabrication process of the electrospun fibrous membranes is closely regulated by the distribution of electric field. To analyze the logic and fabrication mechanism behind structures/structural design of fibrous membranes, the electric field simulations of four substrates S1–S4 were carried out based on the actual process parameters by COMSOL Multiphysics 5.6 with an AC/DC module. , The electric field distribution on the receiving substrates is shown in Figure g–j, from left to right are S1–S4, respectively. Additionally, the corresponding three-dimensional electric field simulation diagrams were also carefully studied (SI Figure S4).…”

Highly Transparent Nanofibrous Membranes Used as Transparent Masks for Efficient PM_0.3 Removal

Currently, the quest for highly transparent and flexible fibrous membranes with robust mechanical characteristics, high breathability, and good filtration performance is rapidly rising because of their potential use in the fields of electronics, energy, environment, medical, and health. However, it is still an extremely challenging task to realize transparent fibrous membranes due to serious surface light reflection and internal light scattering. Here, we report the design and development of a simple and effective topological structure to create porous, breathable, and high visible light transmitting fibrous membranes (HLTFMs). The resultant HLTFMs exhibit good optical performance (up to 90% transmittance) and high porosities (>80%). The formation of such useful structure with high light transmittance has been revealed by electric field simulation, and the mechanism of fibrous membrane structure to achieve high light transmittance has been proposed. Moreover, transparent masks have been prepared to evaluate the filtration performance and analyze their feasibility to meet requirement of facial recognition systems. The prepared masks display high transparency (>80%), low pressure drop (<100 Pa) and high filtration efficiency (>90%). Furthermore, the person wearing this mask can be successfully identified by facial recognition systems. Therefore, this work provides an idea for the development of transparent, breathable, and high-performance fibrous membranes.
