Droplets display many unique properties in soft solid matrices, leading to various fascinating phenomena. These phenomena have inspired multidisciplinary scientific designs involving both fundamental studies and application exploration in the fields of physics, mechanics, chemistry, materials, biology, and so on. These emerging researches are diverse, ranging from artificial trees to antifouling coatings, and have not been concluded from the viewpoint of their composite structures, that is, droplet-embedded soft materials. A comprehensive understanding of these structures will favor the designs of new systems with various predictable properties. We thus review the recent progress of this topic here. This contribution starts from the basic structural characteristics of the droplet-embedded soft materials in the introduction section, followed by the section describing the main fabrication methods to create droplets in soft materials. In the third part, we divide the reported examples into five categories based on the hydrophobicity of the droplets and the miscibility between droplets and matrices and discuss their properties.Afterward, the applications of these systems with droplets are discussed, including self-healing, antifouling surfaces, anticounterfeiting, radiative cooling, and so on. Finally, the promising developments and facing challenges of this topic are proposed. We envision that this review can deliver a comprehensive understanding of droplets in soft matrices and promote the development of this topic.

“…Therefore, the potential applications of the HCP films fabricated by the BF method have been greatly expanded in succession. It has been demonstrated that the HCP films are valuable in the fields of templating and microfabrication [ 62 , 63 ], biomaterials [ 64 ], superhydrophobic surfaces [ 65 , 66 ], sensing [ 60 , 67 , 68 ], catalysis [ 69 , 70 , 71 ], separation [ 72 , 73 , 74 ], responsive surface [ 75 ], coatings [ 76 ], surface-enhanced Raman scattering substrates [ 3 , 77 ], microchannels [ 78 ], and optical and conductive materials [ 79 ]. However, the above-mentioned functionalizing methods for the HCP films used either change homopolymer to copolymers, composites, or blend with the functional components.…”

Modified Breath Figure Methods for the Pore-Selective Functionalization of Honeycomb-Patterned Porous Polymer Films

Recent developments in the field of the breath figure (BF) method have led to renewed interest from researchers in the pore-selective functionalization of honeycomb-patterned (HCP) films. The pore-selective functionalization of the HCP film gives unique properties to the film which can be used for specific applications such as protein recognition, catalysis, selective cell culturing, and drug delivery. There are several comprehensive reviews available for the pore-selective functionalization by the self-assembly process. However, considerable progress in preparation technologies and incorporation of new materials inside the pore surface for exact applications have emerged, thus warranting a review. In this review, we have focused on the pore-selective functionalization of the HCP films by the modified BF method, in which the self-assembly process is accompanied by an interfacial reaction. We review the importance of pore-selective functionalization, its applications, present limitations, and future perspectives.
