“…Currently, various assembly strategies have been developed to align the 1D nanostructures in ordered way. Some strategies such as rubbing, external field–assisted assembly, coassembly, bubble blowing, dip coating, printing, chemical bonding, strain‐release assembly, wrinkle‐assisted assembly, shear coating, and interface‐mediated assembly can lead to a single oriented layer. And some strategies including Langmuir–Blodgett technique, evaporation‐induced assembly, electrospinning, fluidic flow, spray coating, and brush coating can be repeated to form multilayered oriented structures.…”

Transparent conductors for the next generation of soft electronic devices need to be highly stretchable, conductive, and transparent, while an inevitable challenge lies in enhancing them simultaneously. Cost-effective silver nanowires (AgNWs) are widely used but the conventional random network yields a high junction resistance as well as degraded conductivity in the stretched state. Here, a novel, facile, and versatile agitation-assisted assembly approach is reported to control the orientation direction and density of AgNWs and to layer-by-layer deposit the AgNWs monolayer or multilayers onto the prestrained soft substrate. This electrode demonstrates an unprecedented low sheet resistance of 2.8 Ω sq −1 as well as high transparency of 85% and high stretchability of 40%. It is interesting to note that contrary to most other reports, such a device shows higher conductivity in the stretched state compared to the released state. ] for comparison. The designed oriented AgNWs films exhibit relatively lower sheet resistance, higher or comparable transparency and stretchability simultaneously. b) Photograph of the illuminated LED biased at 3 V with our AgNWs-based electrode at the released state (left); photograph of the illuminated LED biased at 3 V using our AgNWs-based electrode when it was stretched for 40% (right). c) Photograph of the illuminated LED biased at 3 V using our AgNWs-based electrode when it was bended for about 180°.

“…This technique serves as an important link between the structure of the solution or sol and the microstructure of the deposited film. Substantial efforts have been devoted for dip coating assembly of NWs on different substrates . As well known, metal NWs such as Au and Ag NWs with advantages of high electrical conductivity, high transparency, good mechanical flexibility, and easy processing have been regarded as most promising alternatives of traditional indium tin oxide for next generation of flexible electronics.…”

The fabrication of nanowire (NW)‐based flexible electronics including wearable energy storage devices, flexible displays, electrical sensors, and health monitors has received great attention both in fundamental research and market requirements in our daily lives. Other than a disordered state after synthesis, NWs with designed and hierarchical structures would not only optimize the intrinsic performance, but also create new physical and chemical properties, and integration of individual NWs into well‐defined structures over large areas is one of the most promising strategies to optimize the performance of NW‐based flexible electronics. Here, the recent developments and achievements made in the field of flexible electronics composed of integrated NW structures are presented. The different assembly strategies for the construction of 1D, 2D, and 3D NW assemblies, especially the NW coassembly process for 2D NW assemblies, are comprehensively discussed. The improvements of different NW assemblies on flexible electronics structure and performance are described in detail to elucidate the advantages of well‐defined NW assemblies. Finally, a short summary and outlook for future challenges and perspectives in this field are presented.

“…[1][2][3] The self-templating process, [4,5] organization via organic matrices, [6,7] spraying, [8][9][10] and evaporation based techniques are among the techniques available for guiding anisotropic object assembly. [11][12][13][14][15][16] The formation of lyotropic liquid crystals directly in bulk or via these evaporation techniques represents an interesting tool. [17][18][19] Where convective evaporation has generated beautifully organized patterned surfaces from inorganic anisotropic objects like nanowires and nanorods [12,15,20] or chiral biological rod-like viruses, [21,22] to the best of our knowledge, the organized assembly of synthetic chiral anisotropic objects…”

Creating Regular Matrices of Aligned Silica Nanohelices: Theory and Realization

Here we exercise nanoscale control over the assembly of highly anisotropic silica helices using convective flow by using the physical properties occurring during evaporation-induced self-assembly. Organizing and patterning such chiral elongated objects over large surfaces in a controllable and reproducible fashion is challenging, but desirable to optimize the performance of biomimetic structures, nano-sensors (mechanical properties of helices) or optical materials (chiral objects have asymmetric interactions with light as absorption is different for left-and right-handed polarization). The coupling of evaporation forces and physicochemical solution properties induce specific helix alignment and the stick-slip phenomenon produces a periodical deposition of bands with controllable and regular spacing. Helix orientation, packing density and spacing can then be tuned. We observe the effect of polymer additives, silica helix concentration, and substrate withdrawal speed on the quality and the orientation of the helix deposition. Theoretical modeling based on capillary hydrodynamics is developed to describe the relationship between evaporative conditions and pitch distance, the band width of the stick region and the helix orientation.
