A Water‐Based Silver‐Nanowire Screen‐Print Ink for the Fabrication of Stretchable Conductors and Wearable Thin‐Film Transistors

Abstract

A water-based silver-nanowire (AgNW) ink is formulated for screen printing. Screen-printed AgNW patterns have uniform sharp edges, ≈50 μm resolution, and electrical conductivity as high as 4.67 × 10(4) S cm(-1) . The screen-printed AgNW patterns are used to fabricate a stretchable composite conductor, and a fully printed and intrinsically stretchable thin-film transistor array is also realized.

Use of biosynthetic silver nanoparticles in the surface sterilization of Pyracantha coccinea stem explants

“…Bitki ekstreleri kullanarak elde edilen gümüş nanopartikül içeren kolloidal çözeltilerin maksimum absorbanslarının 425-439 nm aralığında değiştiği ve bu değerlerin UV-vis spektrumda metalik gümüşün karakteristikleriyle örtüştüğünü belirtmektedir [8], [9]. AgNP'ler tıp, ziraat, kozmetik, kişisel bakım ürünlerinden nanokablo üretimine kadar birçok farklı alanda kullanılan ve başarılı olarak etkinlik gösteren malzemelerdir [11]- [13]. Bu çalışmada, havaciva sulu ekstresi kullanılarak gümüş iyonları indirgenmiş ve spektrofotometrik ve pH analizleri yapıldıktan sonra ateş dikeni gövdesinin yüzey sterilizasyonunda kullanılmışlardır.…”

Fused silver nanowires with silica sol nanoparticles for smooth, flexible, electrically conductive and highly stable transparent electrodes

“…Among these additives, water soluble and eco-friendly HPMC is used as the viscosity modier and lm-forming agent for AgNW inks. 47 Without HPMC, AgNWs will aggregate during the drying process as shown in Fig. S1 in the ESI, † resulting in inhomogeneous distribution and high sheet resistance of over 1 kU sq À1 .…”

All-printed magnetically self-healing electrochemical devices

“…Fragility is the “Achilles’ heel” of the multibillion dollar field of printed electronics. Development of self-healing inks will thus be germane to printed electronics for their numerous applications in scenarios where mechanical damage of devices is common ( 9 , 10 ). …”
