Selectively modulated inkjet printing of highly conductive and transparent foldable polymer electrodes for flexible polymer light-emitting diode applications

Highly Customizable Transparent Silver Nanowire Patterning via Inkjet‐Printed Conductive Polymer Templates Formed on Various Surfaces

“…[ 1–11 ] Currently, indium tin oxide (ITO) is a commonly used TCE in the electronic devices on rigid substrates but its inherent brittleness hinders its application to the flexible electronics because of crack‐induced electrical failure caused by an external force. [ 12,13 ] Among many candidates for the flexible TCEs, [ 14–22 ] silver nanowires (AgNWs) are one of the promising candidates to replace the ITO due to their compatibility with a solution‐process and great optoelectronic properties while exhibiting superior mechanical flexibility. [ 8,9,21,23–26 ] Various papers have reported about fabrication methods of optoelectronic devices with AgNWs including embedding process, which compensates the rough surface of AgNWs.…”

Inkjet printed polystyrene sulfuric acid-doped poly(3,4-ethylenedioxythiophene) (PEDOT) uniform thickness films in confined grooves through decreasing the surface tension of PEDOT inks

“…The inkjet printing approach for manufacturing organic/polymer light-emitting displays (O/PLEDs) has attracted great attention in the last few years because of the non-contact digital printing process, suitability for large area exible substrates, low cost at high speed, and so on. [1][2][3][4][5] The morphological properties of printed photoelectric lms, such as uniformity of thickness and patterning resolution, are of great importance in fabricating reliable printed O/PLEDs and improving their performance.…”

“…The main research into the inkjet printing of PEDOT lms has focused on conductivity promotion through the modication of PEDOT inks to realize ITO free devices. [23][24][25][26][27][28] Rare works have focused on morphology control of inkjet printed PEDOT lms. 29,30 Thickness and lm uniformity of inkjet printed PEDOT lms is very important in ensuring the quality of the next deposited organic light emitting lms beyond PEDOT lms and the performance of printed O/PLEDs.…”

Rapid and Versatile Photonic Annealing of Graphene Inks for Flexible Printed Electronics

“…As previously suggested, a key figure of merit for practical applications is the conductance achieved per printing pass, which scales with the product of ink concentration and film conductivity. A range of competing conductive inkjet‐printable inks is mapped out on axes of ink concentration and conductivity in Figure c, taken from the recent literature for graphene, PEDOT:PSS, RGO, and CNTs (see the Supporting Information for details) . The dashed lines represent isolines of the product of conductivity and ink loading.…”
