“…Inkjet printing of functional materials provides many tunable parameters such as rheology of the inks for a given material, accuracy of patterning, three dimensional overlay accuracy, stitching accuracy of patterns, etc. The challenges that remain are improved uniformity over large areas, deposition of the layers on flexible substrates, morphology, and structure and microstructure optimization [120,121]. Based on the review of literature it can be summarized that low-cost solution-based techniques are emerging as the candidates for large-area self-cleaning applications.…”

Abstract. Surfaces that exhibit reversible wettability toward water are extremely important for a variety of technological applications. In this context, the development of superhydrophobic and superhydrophilic surfaces for self-cleaning applications has been receiving a great deal of attention in the last few years. In this review, an overview of the current state-of-science and technology of self-cleaning surfaces is presented. The current understanding of physics of wetting leading to surfaces with predictive, controllable and reversible wettability is first presented. The review then focuses on materials, mainly metal oxides and their composites, employed for self-cleaning applications. It is shown that, although conventionally oxides and polymers are considered for self-cleaning applications, recent developments point toward the use of artificially engineered surfaces with hierarchical roughness. Applications of self-cleaning films in nonconventional areas such as protection of fabrics, solar cells and structures related to cultural heritage are discussed. The review ends with an outlook for the future in terms of science and technology of self-cleaning surfaces.

“…Off course, precipitation has to be prevented at all times to avoid non-stochiometric precursor solutions. Solution chemistry routes allow beside the formation of bulk ceramics, the deposition of ceramic thin films by dip-coating, spin-coating, spray-coating or even ink-jet printing [4][5][6][7].…”

Microwave synthesis of ZrO₂ and Yttria stabilized ZrO₂ particles from aqueous precursor solutions

Zirconia and Yttrium stabilized zirconia are well-known ceramic materials. Scaling down the dimension of these ceramics can result in a faster sintering process at lower temperatures. Microwave synthesis of nano-structured particles is a very attractive synthesis route because of the short synthesis time and low reaction temperature. This allows a fast screening of the influence of different parameters such as time, temperature and pressure on the final size and crystal phase of the particles. In this study Zr and Zr/Y aqueous precursors are mixed with a variety of complexing agents or surfactants in different ratios. The reason is twofold: (1) we aim for a stable precursor solution which is established by lowering the free ion concentration and (2) we want to see the influence of the complexing agents on the growth of the particles and the formation of crystalline phases. Particle sizes of these particle vary from 40 -200 nm. The crystallinity is confirmed by X-ray diffraction. The stabilization of these particles and possible exchange of the ligands is examined with NMR measurements (1D -proton combined with 2D NOESY) and is compared with TGA-DTA analysis of the isolated particles.

“…Yet, integration of metaloxides on Si-based components remains an area of research with much room for improvement in terms of materials processing. Theoretically, BaTiO 3 , having a very high opto-electronic coefficient, remains one of the most promising materials for use as opto-electronic modulator. Yet, there are some important restrictions hindering its' practical use.…”

“…To reduce optical losses and ensure high modulating efficiency, we need to integrate quasi single crystalline BaTiO 3 (BTO) with perfect epitaxy and extremely smooth surfaces with Si technology. Currently, these requirements can only be fulfilled by other materials with an intrinsic lower opto-electric coefficient such as LiNbO 3 and PbZr 1-x Ti x O 3 or by using PLD, CVD or MBE to deposit BaTiO 3 [1,2].…”

A water-based BaTiO 3 precursor solution, suited for ink-jet printing of hetero-epitaxial BaTiO 3 layers on LaAlO 3 single-crystal substrates was developed. First, a study on the simultaneous stabilization of Ba 2+ and Ti 4+ ions in a neutral, aqueous environment was performed. Thermal analysis of the precursor was used to select appropriate temperature programs and the rheology of the solutions is studied to optimize dipcoating and later ink-jet printing parameters. On both substrates, it was possible to obtain epitaxial layers of about 200 nm thickness after sintering at temperatures above 1000 °C. Currently, we are adapting the thermal program and heating atmosphere in order to reduce the sintering temperatures, decrease the surface roughness and increase density.
