Special Issue Information

Dear Colleagues,

Printing is considered as one of the fastest and least expensive mass production technologies for the manufacturing of thin films and coatings. Inkjet printing advantageously differs from other known methods in a number of ways, such as the capability of printing patterns with high resolution and processing materials with minimal contamination. Inkjet-printed materials have growing fields of application, e.g., in optics, electronics, energy, and medicine. The field of inkjet printing provides vast opportunities for theoretical studies aimed at a fundamental understanding of the underlying physical principles and applied studies in order to develop inkjet printing technology and postprocessing. The aim of this Special Issue is to present recent developments in the field of inkjet-printed films and coatings and reveal outlooks and advantages of inkjet technology for creating thin layers.

In particular, the topics of interest include, but are not limited to:

  • Ink synthesis;
  • Coatings characterization;
  • Problems of strength, adhesion and materials compatibility;
  • Microfabrication;
  • Applications: photovoltaics, optoelectronics, medical applications, biological and chemical sensors; and
  • All other issues relating to inkjet-printed films and coatings.

The tendency to develop flexible and transparent materials has been growing in the last decade. As inkjet printing technology has become a widespread method for the fabrication of functional materials, the investigation of the inkjet printing process seems to be essential with regard to polymers, which are a viscous and flexible media. In this study, we evaluated the dependence of ink drop coalescence on process parameters such as polymer viscosity (controlled by polymerization time), drop spacing and drop speed. The results showed that drop coalescence was mostly influenced by drop speed, while drop spacing and substrate polymer viscosity did not significantly affect the printing results. The presented data are crucial for understanding the processes involved in the fabrication of flexible materials by inkjet printing. Full article

Here we report the methodology for nanocomposite fabrication based on the inkjet printing technique. Doped TiO2 nanoparticles with Sc contents up to 10 wt.% were synthesized and adapted towards a facile fabrication of microscale structures and thin film printing. Implementation of the state-of-the-art low-temperature synthesis allowed to us successfully incorporate high concentrations of Sc3+ ions into the TiO2 lattice and improve the light absorption characteristics of the resulting materials. Without affecting the anatase structure substantially, Sc doping gave rise to an intensified absorbance capacity and provided the means for the efficient fabrication of Sc-TiO2 microarchitectures via the inkjet printing technique. The changes in the spectral and structural characteristics of the Sc-TiO2 composites were observed by Energy Dispersive X-Ray spectroscopy (EDX), X-ray diffraction (XRD), and UV-vis methods. The rheological parameters of the colloidal suspension based on the synthesized Sc-TiO2 nanoparticles were adapted for inkjet printing in terms of the optimal viscosity, morphology, and surface tension. The developed individual ink characteristics allowed us to produce a close coherence between the enhanced optical properties of the Sc-TiO2 prepared the sol–gel method and the inkjet-printed films. The introduced methodology features the possibility to inkjet-print doped and pure TiO2 robust films for potential large-scale fabrication. Full article
