“…Meanwhile, we found the hierarchical wrinkles pattern appeared around the edge of the frame (Figure 2a). Previous studies demonstrated that the hierarchical wrinkling patterns is typical feature of an elastic film on a liquid substrate, [20][21][22][23] which is confirmed by our work.…”

“…[8][9][10][11][12][13][14] Meanwhile, the wrinkles pattern always are inevitable when the metal films are deposited on soft elastic or liquid substrates because of the residual compression between the metal films and the substrates. [15][16][17][18][19][20][21][22][23] The evolutionary rules of buckling structures are fundamental laws of the universe, whose detection in bilayer films are essential for understanding the structures of organisms and the morphology of planets. [24,25] Generally, wrinkles are first type of buckling structures in bilayer films, which can be stimulated by a minor compressive strain.…”

Buckling patterns are universal in organs of living organisms. Moreover, the functional realization of these organs is precisely dependent on the deformation of buckling structures, which is also related to the effect of interfacial interaction between liquid and solid surfaces. However, the detection of synergistic reaction between the buckling pattern and the effect of liquid–solid interface is absent. Herein, an experimental simulation of buckling behaviors at the solid–liquid interface, that is, by depositing Au atoms on liquid polydimethylsiloxane (PDMS) is developed. Buckling patterns can be directly created at the interface of Au atoms film and liquid PDMS. Furthermore, it is demonstrated that the orientation of buckling structures can be strictly controlled depending on the frame edges placed on the surface of the liquid PDMS before the deposition. Various ordered buckling patterns, such as parallel wrinkles pattern, magnetic‐field‐lines‐like buckling pattern, and bionic patterns, can be prepared depending on this buckling behavior. The experimental simulation of the buckling behavior at the liquid–solid interface is well promoted, which may be further helpful in understanding the effect of interfacial interaction between liquid and solid surfaces.

“…The crack period is three to four times the adhesive thickness, in agreement with the experimental observations of interlayer-mediated oscillating cracks. [181][182][183] The shape and property of substrates may greatly influence the crack path of subsequently deposited films. Nandakishore and Goehring investigated the crack patterns in wet clay films on uneven (sinusoidally varying) substrates by desiccation.…”

Constructing wrinkled structures on the surface of materials to obtain new functions has broad application prospects. Here a generalized method is reported to fabricate multi‐scale and diverse‐dimensional oxide wrinkles on liquid metal surfaces by an electrochemical anodization method. The oxide film on the surface of the liquid metal is successfully thickened to hundreds of nanometers by electrochemical anodization, and then the micro‐wrinkles with height differences of several hundred nanometers are obtained by the growth stress. It is succeeded in altering the distribution of growth stress by changing the substrate geometry to induce different wrinkle morphologies, such as one‐dimensional striped wrinkles and two‐dimensional labyrinth wrinkles. Further, radial wrinkles are obtained under the hoop stress induced by the difference in surface tensions. These hierarchical wrinkles of different scales can exist on the liquid metal surface simultaneously. Surface wrinkles of liquid metal may have potential applications in the future for flexible electronics, sensors, displays, and so on.
