Issue Date: | 2018 | Source: | NANOTECHNOLOGY, 29(42) (Art N° 425201) | Abstract: | Silver nanowire networks have demonstrated significant potential as semi-transparent electrodes for various applications. However, for their widespread utilisation in devices, upscaled coating technologies such as screen-printing need to be explored and related to this, the formulation of suitable inks is indispensable. This work contributes to this effort by the synthesis of Ag-NW based formulations. The rheological characteristics that are essential for screen-printing are obtained by the addition of hydrophobically modified cellulose. The electrical and optical characteristics of screen-printed features on PET are compared by a Van der Pauw method and UV–vis spectroscopy. Despite the presence of the cellulose additive, the screen-printed electrodes exhibit a transmittance from 92.8% to 57.3% and a sheet resistance down to 27 Ohm sq−1. Based on the percolation theory in composites, a mathematical expression is presented, which allows the in-depth analysis of the resulting opto-electrical properties. The application potential of the nanowire-containing formulations is finally demonstrated by screen-printing functional, flexible electroluminescent devices. | Keywords: | metallic nanowires; transparent conductive coating; ink formulation; printed electronics; screen-printing; low temperature; modelling | Document URI: | http://hdl.handle.net/1942/28062 | ISSN: | 0957-4484 | e-ISSN: | 1361-6528 | DOI: | 10.1088/1361-6528/aad74d | ISI #: | 000441669200001 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2019 |
