A Lotus‐Leaf‐like Superhydrophobic Surface: A Porous Microsphere/Nanofiber Composite Film Prepared by Electrohydrodynamics

Abstract

Inspired by self-cleaning lotus leaves, superhydrophobic surfaces with water contact angles (CA) larger than 1508 have attracted great interest over the last few years for both fundamental research and practical applications. The fundamental mechanism of this phenomenon proposes that a combination of a hierarchical micro/nanostructure and low-[*] Prof.

Bio‐Inspired, Smart, Multiscale Interfacial Materials

“…Via this simple method a cheap industrial polymer affords superhydrophobicity without any further modification. [82] porous microspheres (Fig. 8) contribute to the superhydrophobicity by increasing the surface roughness, while nanofibers interweave to form a 3D network and reinforce the composite film that is surprisingly similar to a lotus leaf.…”

“…Different chemical and physical methods for the fabrication of rough surfaces and subsequent application of low-surface-energy coatings on these rough surfaces have been explored, e.g., lithography, [77] sublimation, [78] plasma techniques, [79] self-assembled monolayers, [80] electrochemical methods, [81] electrohydrodynamic/electrospinning techniques, [82] and many more. Electrohydrodynamic techniques proved to be effective methods for the preparation of lotus-leaf-like porous microsphere/nanofiber composite films.…”

Reducing the Adhesion between Surfaces Using Surface Structuring with PS Latex Particle

“…27 Bottomup approaches involve mostly self-assembly and self-organization 28 as for instance chemical deposition, 29 layer-by-layer (LBL) deposition, 30 hydrogen bonding, 31 and colloidal assemblies. 32 There are also methods based on the combination of both bottom-up and top-down approaches, for example, casting of polymer solution and phase separation, 33 and electrospinning. 34 Among these methods, the application using two-dimensional (2D) colloidal crystals, "natural lithography", which has been suggested by Deckman and Dunsmuir, 35 has attracted attention due to it being a relatively easy process in comparison with conventional lithography.…”
