“…An interesting option in this direction is the arrangement of the individual photonic particles into arrays (see Figure 6 b, c). 32, 35 The fabrication is made possible with inkjet printing, which is currently extensively used for material deposition and structuring. Such arrays open up possibilities for applications either after the problems with the defects in the individual particles are solved, or for photonic applications that are insensitive to disorder.…”

The beauty of opals results from a densely packed, highly ordered arrangement of silica spheres with a diameter of several hundred nanometers. Such ordered nanostructures are typical examples of materials called photonic crystals, which can be formed by known microstructuring methods and by self-assembly. Opals represent a self-assembly approach to these structured media; such an approach can lead to novel materials for photonics, photocatalysis, and other areas. Although self-assembly leads to many types of defects, resulting in the surprising and very individual appearance of natural opals, it causes also difficulties in technological applications of opal systems.

“…They inkjet printed latex suspension on the hydrophobic substrate, obtained dome-like PC sphere, which can effectively avoid the angle-dependent property of the stopband of PC, providing an important insight for the wide-view display applications of PCs. That is, the hydrophobic substrate provides an effective approach for the fabrication of colloidal crystals with excellent wide-angle property [41][42][43][44][45][46].…”

In this paper, we presented a detailed discussion about the influence of the substrate wettability on the colloidal assembly and the resultant functionality of the films. It covers the basic assembly principle for colloidal crystals, the basic understanding of the substrate wettability on colloidal assembly, and the detailed explanation of the influence by give a full examples of various assembly from the substrate with distinct wettability, such as superhydrophilic, hydrophilic, hydrophobic, superhydrophobic and hydrophilic-hydrophobic pattern substrate.

“…However, the development of concepts and methods for an efficient manufacture of such novel materials is one of the current challenges towards industrial applications. A variety of bottom‐up approaches for preparing spherical aggregates of colloidal particles from monodisperse suspensions have been reported 10–20. They mainly focus on emulsion‐based processes where spherical aggregates are formed by arrangement of particles inside droplets emulsified in liquid media.…”

In‐Flight Inkjet Self‐Assembly of Spherical Nanoparticle Aggregates

Recently, there has emerged a growing interest in many disciplines to use the principle of self‐assembly in order to manufacture ensembles of nanostructures. Self‐assembly processes organize autonomously building blocks into patterns or structures without human intervention. We report on combining inkjet printing and self‐assembly as a manufacturing method for spherical aggregates. The aggregates consist of a high number of colloidal nanospheres arranged as stable ball‐shaped structures. The method allows the patterned deposition of spherical aggregates on any surface due to an in‐flight self‐assembly process of the nanospheres.
