TLDR
The overall properties of transparent Ag NW electrodes meet the requirements of transparent electrodes for many applications and could be an immediate ITO replacement for flexible electronics and solar cells.Abstract:
We report a comprehensive study of transparent and conductive silver nanowire (Ag NW) electrodes,includingascalablefabricationprocess,morphologies,andoptical,mechanicaladhesion,andflexibility properties, and various routes to improve the performance. We utilized a synthesis specifically designed for long andthinwiresforimprovedperformanceintermsofsheetresistanceandopticaltransmittance.Twenty/sqand 80% specular transmittance, and 8 ohms/sq and 80% diffusive transmittance in the visible range are achieved, whichfallinthesamerangeasthebestindiumtinoxide(ITO)samplesonplasticsubstratesforflexibleelectronics andsolarcells.TheAgNWelectrodesshowopticaltransparenciessuperiortoITOfornear-infraredwavelengths(2- foldhighertransmission).Owingtolightscatteringeffects,theAgNWnetworkhasthelargestdifferencebetween diffusive transmittance and specular transmittance when compared with ITO and carbon nanotube electrodes, a propertywhichcouldgreatlyenhancesolarcellperformance.AmechanicalstudyshowsthatAgNWelectrodeson flexiblesubstratesshowexcellentrobustnesswhensubjectedtobending.Wealsostudytheelectricalconductance ofAgnanowiresandtheirjunctionsandreportafacileelectrochemicalmethodforaAucoatingtoreducethewire- to-wire junction resistance for better overallfilm conductance.

Laser-induced single point nanowelding of silver nanowires
TL;DR: In this paper, the precise control of single point nanowires is explored in depth, where the nanowelding is laser-induced through the plasmonic resonance enhanced photothermal effect.

Mass Production of Nanowire-Nylon Flexible Transparent Smart Windows for PM2.5 Capture
TL;DR: It is demonstrated that large-area fabrication of flexible transparent Ag-nylon mesh can be performed not only to turn the indoor light illumination intensity as thermochromic smart windows after uniformly coating with thermochROMic dye but also to purify indoor air as high-efficiency PM2.5 filter.

Organic‐Stabilizer‐Free Polyol Synthesis of Silver Nanowires for Electrode Applications
TL;DR: It is demonstrated that Ag NWs can be produced in high yield without any organic stabilizers simply by introducing trace amounts of NaCl and Fe(NO3 )3 during low-temperature polyol synthesis.

Uniformly embedded silver nanomesh as highly bendable transparent conducting electrode
TL;DR: Ag-nanomesh-based highly bendable conducting electrodes are developed using a combination of metal nanotransfer printing and embossing for the 6-inch wafer scale to demonstrate the enhancement of bending stability when the Ag nanomesh is embedded in the PET substrate.

Design of UV-Absorbing Polypropylene Films with Polymeric Benzotriaziole Based Nano- and Microparticle Coatings.
TL;DR: The thin coatings obtained by the PNB NPs were superior to those of the P NB MPs, in that no UV transmittance or loss of optical properties of the PP films were observed for the NP coatings, while the coatings produced by thePNB MPs resulted in damaged optical properties, particularly increasing the haze, and achieved incomplete UV blocking.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

TL;DR: The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.
