“…Huang et al reported a new method [ 106 ] that enables the creation of low-surface-energy polymer coatings from ordered nanoscale conical arrays using a CVD process. The polymer coatings are then plasma treated in a vacuum chamber, where the plasma treatment activates surface hydroxyl groups to facilitate grafting with silicones.…”

As research on superhydrophobic materials inspired by the self-cleaning and water-repellent properties of plants and animals in nature continues, the superhydrophobic preparation methods and the applications of superhydrophobic surfaces are widely reported. Silicones are preferred for the preparation of superhydrophobic materials because of their inherent hydrophobicity and strong processing ability. In the preparation of superhydrophobic materials, silicones can both form micro-/nano-structures with dehydration condensation and reduce the surface energy of the material surface because of their intrinsic hydrophobicity. The superhydrophobic layers of silicone substrates are characterized by simple and fast reactions, high-temperature resistance, UV resistance, and anti-aging. Although silicone superhydrophobic materials have the disadvantages of relatively low mechanical stability, this can be improved by the rational design of the material structure. Herein, we summarize the superhydrophobic surfaces made from silicone substrates, including the cross-linking processes of silicones through dehydration condensation and hydrosilation, and the surface hydrophobic modification by grafting hydrophobic silicones. The applications of silicone-based superhydrophobic surfaces have been introduced such as self-cleaning, corrosion resistance, oil–water separation, etc. This review article should provide an overview to the bioinspired superhydrophobic surfaces of silicone-based materials, and serve as inspiration for the development of polymer interfaces and colloid science.

“…A superhydrophobic membrane of P(PFDA-co-EGDA) with a cone structure was polymerized on a polyethylene glycol diacrylate (PEGDA) membrane via iCVD. 44,165 While the partial pressure of PFDA in the chamber was above the saturation pressure of PFDA, the PFDA monomer was supersaturated on the PEGDA surface and nucleated to form nuclei as nanodroplets. Then, the PFDA monomer was adsorbed and polymerized on the cores to build a conical structure.…”

Vapor deposition of polymers is known to result in densified thin films, and recent developments have advanced these polymers with interesting fabrication techniques to a variety of controlled structures other than thin films. With the advantages of chemical modification and functionalization of these polymers, advancements have combined both the physical and chemical properties of these vapor-deposited polymers to obtain controlled anisotropic polymers, including layer-by-layer, gradient, hierarchical, porosity, and the combination of the above, meaning that the produced polymers are functional and are addressed in devised physical configurations and chemical compositions. The main purpose of using polymer coatings as a tool for surface modification is to provide additional properties that decouple the natural properties of the underlying materials (including metals, polymers, oxides/ceramics, glass, silicon, etc.), and recent advancements have rendered novel insights into combined physical and chemical properties to fulfill the increasing needs of sophisticated requirements of materials for users. The review herein intends to deliver messages of recent progress of the advancements of vapor-deposited polymers, with discussions of the variations of the physical structures and chemical functionalities, and how these two aspects are integrated with novel fabrication techniques.

“…Self-cleaning often relies on superhydrophobicity, which reduces the water adhesion on the device surface and enables the rapid slide of water droplets.

Silica glass devices are widely used due to their exceptional physical and chemical properties. However, prolonged usage may result in abrasion and contamination of silica glass devices, adversely affecting the service life. One of the most effective solutions to this issue is surface modification, in which superhydrophobicity with high transmittance and mechanical robustness is highly desired. Inspired by the concept of protective armor, we proposed a novel approach for the direct integration of robust and transparent superhydrophobic structures on silica glass. In this method, microstereolithography synergistic heat treatment processes are used to create a micrometerscale biomimetic frame on the surface of silica glass and then filled with in situ deposited nanoparticles. The superhydrophobicity of the surface can be obtained through the nanoparticles, and the biomimetic frame can protect the surface from direct contact with external objects to achieve durability. This process allows the preparation of superhydrophobic silica structures on the silica device surface at temperatures below its melting point, which prevents any damage to the devices during the heat treatment. Moreover, up to 90% transmittance does not affect the performance of silica devices. The composite structure maintains a contact angle of over 150°after multiple abrasion tests, verifying the mechanical robustness. This innovative process paves the way for forming a high mechanical robustness and excellent transmittance protective layer on silica glass devices, which expands the application field.
