“…The characteristic spatial scales of patterns vary from nanometers to dozens of micrometers. Consider the largescale patterning observed in rapidly evaporated polymer solutions [94][95][96][97][98][99], depicted in Figure 3, observed under the dip-coating of substrates with rapidly evaporated polymer solutions (similar large-scale patterns were observed also under other experimental techniques [96][97][98][99]). In particular, it was demonstrated that the characteristic dimension of cells constituting the pattern grow with the concentration of the polymer solution [95].…”

“…2D and 3D hierarchical structures, possessing a range of scales from micro-meters to nano-meters were reported [14,35,150]. The nature of the large-scale (~ 10 m) patterning, attributed by different authors to various kinds of hydrodynamic instabilities remains disputable [95][96][97][98][117][118].…”

“…The experimental data reported in Refs. 95,115 convince, that this is the solutal Marangoni flow, which constitutes the pattern. Indeed, heating the substrate from below destroyed the patterning [115].…”

“…This means that the effects due to gravity, inertia and viscosity are negligible, and the breath figures self-assembly is mainly driven by the interfacial phenomena (however, the viscosity, growing with the evaporation of the polymer solution layer, helps to stabilize the eventual honeycomb pattern, as it will be shown below). Indeed, the breath figures patterns were observed on horizontal [14][15][16] and vertical [46,[95][96][97] substrates. It is seen from Eqations 4, that the breath-figures self-assembly is a "slow" process, in which effects due to inertia and viscosity are negligible.…”

Abstract:The review is devoted to the physical, chemical and technological aspects of the breath-figures self-assembly process. Main stages of the process and the impact of the polymer architecture and physical parameters of the breath-figures self-assembly on the eventual pattern are covered. The review is focused on the hierarchy of spatial and temporal scales inherent for the breath-figures self-assembly. Multi-scale patterns arising from the process are addressed. The characteristic spatial lateral scales of patterns vary from nanometers to dozens of micrometers. The temporal scales of the process span from micro-seconds to seconds. The qualitative analysis performed in the paper demonstrates that the process is mainly governed by the interfacial phenomena, whereas the impact of inertia and gravity is negligible. Characterization and applications of polymer films manufactured with breath-figures self-assembly are discussed.

“…The origin of this pattern is not clear, and is related by many researchers to various kinds of interfacial instabilities: Marangoni (surface-tension-driven), evaporation or masstransport-driven ones. [23][24][25][33][34][35][36][37][38][39][40][41][42] The high dispersion of pore sizes seen in Figure 2 makes this pattern unsuitable for most of the applications mentioned above.…”

A method of manufacturing free‐standing, micrometer‐scale honeycomb polyetherimide films is reported for the first time. Films are manufactured with a dip‐coating technique under water‐assisted self‐assembly. It is shown that the addition of poly(organosilane/siloxane)s and poly(ethylene glycol) allows the formation of regular honeycomb patterns. The films demonstrated the high thermal stability inherent for polyetherimide. The wetting properties of films are reported. The presence of nanopores was revealed with SEM imaging of the films. The makeup of the films allows their use as asymmetric membranes for reverse osmosis and ultrafiltration.magnified image
