Preparation and influence of highly concentrated screen-printing inks on the development and characteristics of thick-film varistors

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

“…This recovery time and viscosity allow for leveling of the ink and uniform line formation. Moreover, the recovery of the viscosity for the AgNW Ink‐M at the time of 110 s was higher than 80%, which is an indication of good elasticity of the ink . Generally, the viscosity for the typical inks based on silver particles/flakes, even when formulated with very high solid contents of >60 wt%, can hardly exceed 70% recovery .…”

“…Oscillatory rheological measurements were also carried out for the AgNW Ink‐M to further characterize the viscoelastic effect of the ink in a stress sweep step (SSS) test. The curves of the variation of “storage modulus” G ′ (elastic component) and “loss modulus” G ″ (viscous component) for AgNW Ink‐M as a function of shear stress are presented in Figure d, and are divided into three regions . Figure e illustrates the variation of tan δ ( G ″/ G ′) as a function of shear stress.…”

Recent advances in printable thermoelectric devices: materials, printing techniques, and applications

“…Moreover, the screen printed lm is known to have a rough surface and are susceptible to cracking and delamination. 74,77 Screen printing is one of the most popular methods used to print thermoelectric devices (Table 3). Both organic and inorganic inks has been used in conjunction with this method.…”

Printed thermoelectric materials and devices: Fabrication techniques, advantages, and challenges

“…The negative of the mesh structure can be reproduced in the surface of printed patterns. This significantly increases surface roughness . For vertical structures the rough top surface increases the contact resistance between it and subsequent layers.…”
