Large‐Scale Direct‐Writing of Aligned Nanofibers for Flexible Electronics

The potentialities of miniaturized laser sources are still far from being fully developed. Unprecedented opportunities are generated in this field by organic nanowires and nanofibers, which can be used as building blocks of micro‐ and nanolasers in which they combine optical gain, waveguiding, and very high versatility to create nanophotonic networks. The progress in laser devices and network architectures based on optically pumped organic light‐emitting nanowires and nanofibers is here presented, with emphasis on developed active materials, fabrication technologies, lasing mechanisms, and cavity geometries, and on achieved device performance in terms of spectral tunability, excitation threshold, and resonator quality factors. Recent examples of optical coupling of different miniaturized lasers, of their application in optical sensing, and of network lasers are presented. Future directions for research are also outlined, which include the exploration of new classes of active organic or hybrid materials within nanowires, the more in‐depth characterization of the fundamental properties of these lasers, and the use of topologically defined organic nanophotonics in network science, computing, and diagnostics.

Flexible substrates play a decisive effect on the functions of flexible energy storage devices. However, systematical investigation and understanding of often-used flexible carbon-based substrates is lack. In this work, a reliable cotton cloth induced flexible hierarchical carbon film is facilely obtained. The synthesized-carbonized cotton cloth (SCC) owns distinctive carbon nature with perfect order level and defects, unique porous microstructure, and crosslinked-network. The SCC exhibits favorable flexibility, fast kinetics, high structural and electro-chemical durability with high performance (239.4 mAh g À 1 and 155.2 mAh g À 1 at 0.01 A g À 1 in the ether-and ester-based electrolyte in sodium-ion batteries, respectively), superior to commonly-used commercial carbon cloth and graphene film. In addition, the predominant surface-controlled reaction mechanism, effective solid electrolyte interphase and favorable compatible features with different electrolytes are also intensively studied.

“…Orderly assembling thin conducting fibres into an array or three-dimensional (3D) structures up-scales their functional performance for device coupling. Developing new strategies to control rapid synthesis, patterning and integration of these conducting elements into a device architecture could mark an important step in enabling new device functions and electronic designs (4,5). To-date, conducting micro/nano-scaled fibres have been produced and assembled in a number of ways, from transferring of chemically-grown nanofibers/wires (6,7), writing electrohydrodynamicalldeposited lines (8,9), to drawing ultra-long fibres (10,11), wet-spinning of fibres (12)(13)(14) and 2D/3D direct printing (15)(16)(17)(18).…”

Scalability and device-integration have been prevailing issues limiting our ability in harnessing the full potential of small-diameter conducting fibres. We report inflight fluidic fibre printing, a rapid, low-cost route that integrates the entire process of conducting fibre production and fibre-to-circuit connection, in a single step under sub-100 °C ambient atmospheres. Metallic (silver) or organic (PEDOT:PSS) fibres with 1-3 μm diameter are fabricated, and the fibre arrays exhibit over 95 % transmittance in the 350-750 nm region. We exploit combinations of the unique fibre characteristics: directionality, high surface-area-to-volume ratio, and permissiveness, along with transparency and conductivity. Using PEDOT:PSS fibres as a cell-interfaced impedimetric sensor and a moisture sensor, we show that even a single fibre component can achieve complex functions or outperform conventional film-based devices. The capability to design suspended fibres and networks of homo-, hetero-cross-junctions, paves the way to applications including flow-permissive devices, and 3D optoelectronic and sensor architectures.
