“…For example, Xu et al used an alkylcyanoacrylate (ACA, 132) solution in chloroform to prepare BFAs. 102 Condensed water droplets on the solution surface acted not only as templates to generate pores but also as initiators triggering the polymerization of ACA. After the evaporation of solvent and the polymerization of monomers, polyalkylcyanoacrylate (PACA) BFA films were obtained.…”

“…These biocompatible BFAs always show enhanced performance of cell attachment, spreading, and proliferation compared with the unpatterned polymer films 50b. 52d,f, 53 The pore size and shape of BFA have considerable influence on the cell behavior: the enhanced effect of cell adhesion, spreading, and proliferation are more prominent with the decrease of pore size,50b, 54 and there seems to exist a threshold pore size for cell adhesion, which is dependent on the chemical properties of the polymer;55 when the films are stretched, cells proliferate along the direction of the long axis of the micropores 50. Furthermore, the chemical properties of the film and the surface also play important roles in cell behavior 56.…”

A breath figure (BF) is the water droplet array that forms when moisture comes in contact with a cold substrate. This water droplet array has been widely utilized in the past two decades as a versatile soft template for the fabrication of polymeric porous films. Accordingly, the ordered pores on the polymer films formed with such a method are named a breath figure array (BFA).The BF templating technique is undergoing rapid development. Several unconventional BF processes have been established to prepare porous films with unique morphologies or primary materials, and various newly developed functionalization techniques have significantly improved the performance of polymeric films with BFA, leading to novel applications, including templates, biosensors, and separation membranes. These recent achievements will be described in this Minireview.

“…The Confocal Laser Scanning microscope (CLSM) images of thus patterned smooth and constrained surfaces for all molar fraction of methanol in the binary system are shown in Figures 4,5,7,9, Figure 5a indicates that, the introduction of 10% of methanol decreased the pore size and nearest neighbor pore distance to 1.65µm and 800nm respectively. Therefore, it is inferred from the observations that the pore diameter can be controlled by the percentage of methanol in the binary system forming saturated vapor atmosphere.…”

In this paper, the self-assembly of condensed droplets on smooth and constrained surfaces under saturated vapor atmosphere of ethanol and methanol binary system is reported. Hexagonally ordered array of pores are obtained on smooth surfaces with saturated vapors of binary liquids without the assistance of any additives. The results show that the addition of a small amount of ethanol to methanol plays a role very similar to that of surface active agents in inducing the formation of a regular droplet array. The effect of constraints on a self-assembled droplet pattern such as the movement of the contact line and the depinning of the contact line is also investigated. It is observed that the pore size, pore shape, pore depth and ring diameter are influenced by the atmosphere of binary vapors in addition to the commonly held attribution to the surface tension of the solvent. Contact angle studies of the patterned substrates show hydrophobicity with high adhesiveness and transitions between the Wenzel and Cassie impregnating state over the entire concentration region.
