Vår fabrikasjonsmetode kan endres ytterligere for å tillate skalerbarhet av funksjonens størrelser og områder av prøven og for bruk av ulike materialer. Den vellykkede produksjonen av sub-mikrometerlinjebredde ( Figur 3a-3c ) kobber EMTEer ved hjelp av EBL viser at EMTE-strukturen og hovedtrinnene i LEIT-fabrikasjon, inkludert elektroplating og overføring av overføringer, kan pålides pålitelig ned til et sub-mikrometerområde. På samme måte kan andre stor-området litografipr...

Over hele verden blir det gjennomført studier for å lete etter erstatninger for stive transparente ledende oksider (TCOs), for eksempel indiumtennoksid og fluor-dopet tinnoksid (FTO) fi lms, for å fremstille fleksible / tøybare TE som skal brukes i fremtidig fleksibel / Strekkbare optoelektroniske enheter 1 . Dette krever nye materialer med nye fabrikasjonsmetoder. Nanomaterialer, slik som grafen 2 , ledende polymerer 3 , 4 , karbonnanorør 5 og tilfeldige metallnettetråder 6 , 7 , 8 , 9 , 10 , 11 , har blitt studert og har demonstrert deres evner i fleksible TE, som retter seg mot manglene i Eksisterende TCO-baserte TE, Inkludert fiam-sårbarhet 12 , lav infrarød transmittans 13 og lav overflod 14 . Selv med dette potensialet er det fortsatt utfordrende å oppnå høy elektrisk og optisk konduktans uten forringelse under kontinuerlig bøyning. I dette rammeverket utvikler vanlige metallnett 15 , 16 , 17 , 18 , 19 , 20 som en lovende kandidat og har oppnådd bemerkelsesverdig høy optisk gjennomsiktighet og lavt arkmotstand, som kan justeres på etterspørsel. Imidlertid har den omfattende bruken av metallnettbaserte TE&#39;er blitt forhindret på grunn av utallige utfordringer. For det første innebærer fremstilling ofte den dyre, vakuumbaserte avsetningen av metaller 16 , 17 , </sup&gt; 18 , 21 . For det andre kan tykkelsen lett forårsake elektrisk kortslutning 22 , 23 , 24 , 25 i tynnfilm organiske optoelektroniske enheter. For det tredje resulterer den svake adhesjonen med substratoverflaten i dårlig fleksibilitet 26 , 27 . Ovennevnte begrensninger har skapt en etterspørsel etter nye metallnettbaserte TE-strukturer og skalerbare tilnærminger for deres fabrikasjon. I denne studien rapporterer vi en ny struktur av fleksible TE&#39;er som inneholder et metallnett fullstendig innebygd i en polymerfilm. Vi beskriver også en nyskapende, løsningsbasert og billig produksjonstilnærming som kombinerer litografi, elektrodeposisjon og overføringsoverføring. FoM-verdier så høye som 15 k har blitt oppnådd på prøve-EMTE. På grunn av den innebygde naturen avEMTEer, bemerkelsesverdig kjemisk, mekanisk og miljømessig stabilitet ble observert. Videre kan den løsningsbehandlede fabrikasjonsteknikken som er etablert i dette arbeidet potensielt brukes til lavpris og høy gjennomstrømningsproduksjon av de foreslåtte EMTEene. Denne fabrikasjonsteknikken er skalerbar til finere metall-mesh linewidths, større områder og en rekke metaller.

scalable solution-processed fabrication strategy for high-performance, flexible, transparent electrodes with embedded metal mesh

Her rapporterer forfatterne den innebygde metallgjennomskinnelige gjennomsiktige elektroden (EMTE), en ny gjennomsiktig elektrode (TE) med et metallnett fullstendig innebygd i en polymerfilm. Dette papiret presenterer også en billig, vakuumfri produksjonsmetode for denne nye TE; Tilnærmingen kombinerer litografi, elektroplating og overtrykksoverføring (LEIT) prosessering. EMTE-embedded-karakteren gir mange fordeler, for eksempel høy overflatejevnhet, noe som er avgjørende for organisk produksjon av elektronisk utstyr; Overlegen mekanisk stabilitet under bøyning; Gunstig motstand mot kjemikalier og fuktighet; Og sterk vedheft med plastfilm. LEIT-fabrikasjon har en galvaniseringsprosess for vakuumfri metallavsetning og er gunstig for industriell masseproduksjon. Videre tillater LEIT å fremstille metallnett med et høyt aspektforhold ( dvs. tykkelse til linjebredde), betydelig forbedring av sin elektriske konduktans uten å negativt miste optisk transmittance. Vi demonstrerer flere prototyper av fleksible EMTEer, med arkresistanser lavere enn 1 Ω / kvadrat og overføringer større enn 90%, noe som resulterer i svært høye verdifall (FoM) - opp til 1,5 x 10 4 - som er blant de beste verdiene i Publisert litteratur.

Figur 1 viser skjematisk og fabrikasjons flytdiagram for EMTE-prøvene. Som vist i figur la , består EMTE av et metallnett fullt embedd i en polymerfilm. Maskens overkant er på samme nivå som underlaget, og viser en generelt jevn plattform for etterfølgende enhetsproduksjon. Fremstillingsteknikken er skjematisk forklart i figur 1b - e . Etter spincoating en fotoresistfilm på et...

Scalable Solution-processed Fabrication Strategy for High-performance, Flexible, Transparent Electrodes with Embedded Metal Mesh

Denne protokollen beskriver en løsningsbasert fabrikasjonsstrategi for høyytende, fleksible, gjennomsiktige elektroder med fullt innebygd, tykt metallnett. Fleksible gjennomsiktige elektroder som er fremstilt ved denne prosessen, viser blant de høyest rapporterte forestillinger, inkludert ultra-lavt arkmotstand, høy optisk transmittans, mekanisk stabilitet under bøyning, sterk substratadhesjon, overflatejevnhet og miljøstabilitet.
