Investigation of Printing Properties on Paper Substrate

Abstract

In this article, the optimum printing parameters were found when using silver nanoparticle ink to print on Kodak 4-Star photo paper substrate. Fujifilm Dimatix 2831 was used as the inkjet printer. The printing parameters of interest included the number of printing layers, the drop spacing, and curing temperature of the ink. Analysis of Variance (ANOVA) analysis of the experimental data reveals sintering temperature to be significant (p < 0.05) to improve the conductivity. Pattern conductivity and surface roughness were used to identify the optimum printing parameters. The optimum printing parameters were found to be 15 μm drop spacing, two printing layer, and a sintering temperature of 90 • C. The best conductivity measured under the above mentioned condition was found to be 5.56 × 10 6 −1 m −1 . Further, the bending test indicated that the printed patterns were unaffected (in terms of conductivity) when flexed around a cylindrical support indicating excellent stability under stress. This study paves the way for developing mechanically robust flexible devices with excellent electrical properties for Internet of Things (IoT) applications.

Inkjet-Printed Flexible Temperature Sensor Based on Silver Nanoparticles Ink

“…For instance, the research in [4] and [5] have claimed their devices' performances are excellent when using gold (Au) and copper (Cu) inks, respectively. However, the temperature of the paper substrate is not able to withstand both the required curing temperatures of the Au and Cu inks [6]. Compared to the Au and Cu inks, the silver nanoparticles ink (AgNPs) has been highly recommended due to the fact that AgNPs has low reactivity to air [7], minimal resistance to corrosion [8], a lower melting temperature [9] and lower costs [10].…”

Printed Microwave Frequency Humidity Sensor Operating With Phase Shifting Scheme

“…rinting technologies have been involved intensively in a bid of improving the competitivness of wireless sensors considering cost, performance, and ease of implementation. These improvements impacted fields like the Internet of Things, industrial safety, and automotive systems [1][2][3][4]. In that respect, various sensing schemes imparted from printing materials properties have been proposed.…”

Inkjet Printing on a New Flexible Ceramic Substrate for Internet of Things (IoT) Applications

“…Optimization of the printer parameters for the selected ink and substrate combination is mandatory to guarantee high printing quality, as inks with varying viscosity and surface tension interact differently with various substrates. The authors have prior experience in optimizing printing properties on different substrates [ 24 , 25 ]. A fundamental requirement for robust device implementation is the device integrity at room temperature and high temperature in addition to flat and bent conditions.…”
