    Abstract: Superhydrophobic (SHPB) surfaces with tunable adhesion have attracted substantial research interest due to their broad applications. Surface adhesion is a critical parameter that is used to determine the dynamics of water droplets, including liquid pining and releasing. In this study, a facile dewetting strategy is developed to finely tune adhesion on SHPB copper surfaces in a controllable manner. Using this approach, various liquid manipulation behaviors are demonstrated. Copper nanofiber textures (CNFTs) with different surface morphologies, including nanofiber array, bundled nanofibers, and hierarchical micro‐/nanocomposite structures facilitate different dewetting processes of the silicone oil solution via different capillary pathways, which lead to different localization of the silicone oil. Consequently, the CNFTs exhibit tunable adhesion ranging from 8.5 to 104.7 µN, while exhibiting superhydrophobicity. It is proposed that the continuity of the three‐phase contact line plays a crucial role in determining the surface adhesion, which varies from a continuous state on nanofiber array to a discontinuous state on micro‐/nanocomposite textures. Taking advantage, various droplet manipulation behaviors, such as the loss‐less transfer, stretchable deformation, and the directional droplet rolling, are demonstrated using CNFTs with different adhesion. It is envisioned that the proposed strategy will elucidate the fabrication of functional SHPB surfaces.

    Direct Writing Large‐Area Multi‐Layer Ultrasmooth Films by an All‐Solution Process: Toward High‐Performance QLEDs

    Abstract: With increasing the film area/layer, deteriorating in both smoothness and uniformity of thin‐films frequently happen, which remains a barrier for making large‐area quantum dot light‐emitting diodes (QLEDs) by solution processes. Here, we demonstrated a facile all‐solution process guided by the conical fiber array to write multi‐layer ultrasmooth thin‐films directly in centimeter scale. The side‐by‐side fibrous array helps to align surface tensions at the tri‐phase contact line to facilitate large‐area homogeneous deposition, which was verified by theoretical simulation. The Laplace pressure along individual conical fiber contributes to the steady liquid transfer. Thin‐films with small roughness ( 〈 2.03 nm) and large‐area (2×2 cm 2 ) uniformity were prepared sequentially on the target substrate, leading to large‐area high‐performance QLEDs. The result offers new insights for fabricating large‐area high‐performance thin‐film devices.

    Electrochemical On‐Site Switching of the Directional Liquid Transport on a Conical Fiber
    Wiley ; 2022

    Abstract: Directional liquid transport (DLT), especially that proceeding on a conical fiber (DLT‐CF), is an important mass‐transfer process widely used both by natural organisms and in practical applications. However, on‐site switching of the DLT‐CF remains a challenge due to the nontunable driving force imparted by the structural gradient, which greatly limits its application. Here, unprecedently, a facile electrochemical strategy is developed for reaching the on‐site switchable DLT‐CF, featuring in situ control and fast response. Depending on the poised electric potential, the droplet can either move directionally or be pinned at any position for a tunable duration time, exhibiting completely different moving characteristics from the traditional DLT‐CF with no control. It is proposed that the surface hysteresis resistance, closely related to both the surface hydrogen‐bonding network and the droplet topology on the fiber, can be largely altered electrochemically. The tunable hysteresis resistance works synergistically with the conical‐structure‐induced Laplace pressure to on‐site tune the forces acting on the droplet, leading to various controllable DLTs‐CF, including those with tunable distance and direction, array manipulation, and assembly line processing of droplets. The strategy is applicable for versatile liquids, offering a general approach for controllable liquid transport in fibrous systems.

    Direct Writing Micropatterns with a Resolution up to 1 µm

    Abstract: Solution processes have been widely used to fabricate micropatterned surfaces for its mild operation conditions. However, current approaches suffer from limitations of either low resolution or high cost. Here, a facile approach is proposed for direct writing micropatterns with a resolution up to ≈ 1 µm using a unit of triple conical fibers with the side‐by‐side parallel arrangement. With this unit, the resolution of the micropatterns can be mainly controlled by the single central conical fiber, with one side of the fiber facilitating continuous and steady liquid transfer onto the substrate and the other side mechanically supporting the whole unit. Particularly, the unit enables tunable dimension of the micropatterns within a rather large scale from ≈ 1 µm to ≈ 1.3 mm by varying the writing parameters (speed, height, and angle). Moreover, the unit is applicable for direct patterning various liquids, even into microline arrays, with a high resolution. It enables direct writing conductive microline with a width of ≈ 1 µm in a centimeter length scale, which can be used for constructing microcircuits. It is envisioned that the result offers a new perspective for preparing high‐resolution micropatterns using solution processes.

    Aligning Ag Nanowires by a Facile Bioinspired Directional Liquid Transfer: Toward Anisotropic Flexible Conductive Electrodes

    Abstract: Recent years have witnessed the booming development of transparent flexible electrodes (TFEs) for their applications in electronics and optoelectronic devices. Various strategies have thus been developed for preparing TFEs with higher flexibility and conductivity. However, little work has focused on TFEs with anisotropic conductivity. Here, a facile strategy of directional liquid transfer is proposed, guided by a conical fibers array (CFA), based on which silver nanowires (AgNWs) are aligned on a soft poly(ethylene terephthalate) substrate in large scale. After further coating a second thin layer of the conductive polymer poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate), a TFE with notable anisotropic conductivity and excellent optical transmittance of 95.2% is prepared. It is proposed that the CFA enables fine control over the receding of the three‐phase contact line during the dewetting process, where AgNWs are guided and aligned by the as‐generated directional stress. Moreover, anisotropic electrochemical deposition is enabled where the Cu nanoparticles deposit only on the oriented AgNWs, leading to a surface with anisotropic wetting behavior. Importantly, the approach enables alignment of AgNWs via multiple directions at one step. It is envisioned that the as‐developed approach will provide an optional approach for simple and low‐cost preparation of TFE with various functions.

    A Facile One‐Step Approach for Constructing Multidimensional Ordered Nanowire Micropatterns via Fibrous Elastocapillary Coalescence

    Abstract: Nanowire (NW) based micropatterns have attracted research interests for their applications in electric microdevices. Particularly, aligning NWs represents an important process due to the as‐generated integrated physicochemical advantages. Here, a facile and general strategy is developed to align NWs using fibrous elastocapillary coalescence of carbon nanotube arrays (ACNTs), which enables constructing multidimensional ordered NW micropatterns in one step without any external energy input. It is proposed that the liquid film of NW solution is capable of shrinking unidirectionally on the top of ACNTs, driven by the dewetting‐induced elastocapillary coalescence of the ACNTs. Consequently, the randomly distributed NWs individually rotate and move into dense alignment. Meanwhile, the aggregating and bundling of ACNTs is helpful to produce carbon nanotube (CNT) yarns connecting neighboring bundles. Thus, a micropatterned NW network composed of a top‐layer of horizontally aligned NWs and an under‐layer of vertical ACNT bundles connected by CNT yarns is prepared, showing excellent performance in sensing external pressure with a sensitivity of 0.32 kPa −1 . Moreover, the aligned NWs can be transferred onto various substrates for constructing electronic circuits. The strategy is applicable for aligning various NWs of Ag, ZnO, Al 2 O 3 , and even living microbes. The result may offer new inspiration for fabricating NW‐based functional micropatterns.
