“…In contrast to the aforementioned two strategies, a one‐pot method is deemed to be simpler for the fabrication and thereby has frequently been studied . Recently Lin et al applied an in situ one‐step vapor phase polymerization method to prepare electrically conductive superamphiphobic fabrics with polypyrrole in conjunction with fluorinated alkylsilane .…”

“…Additionally, a facile one‐step i‐CVD route has been developed by Kim et al to fabricate a robust superamphiphobic coating on a sponge surface, in which no additional solvent was required, thereby resulting in an all‐dry vapor‐phase process . By such a single simple step of the i‐CVD process, the poly(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10‐heptadecafluorodecyl methacrylate) was successfully deposited onto both the interior and exterior of the sponge structure relying on the polymerization of fluoroalkyl acrylates ( Figure ).…”

Among diverse wetting phenomena in surface science, superamphiphobicity is regarded as one of the most special super-antiwetting states. In this paper, a systematic summary is presented to cover the characterization of surface wettability, the construction techniques, and selected functional applications. With respect to fabrication techniques, the following three types of technology routes, viz., "pre-texturing + post-modifying," "pre-modifying + posttexturing," and in situ one-step construction will be discussed. The merits and demerits of each technology route are discussed. It is vital to rationally design or adopt appropriate construction strategies in diverse conditions. Appropriately constructed superamphiphobic multifunctional surfaces can be applied in many fields, however, most have not been scaled-up and utilized for practical applications due to some specific difficulties required to be resolved in the future. These challenges and further outlook for super-antiwetting surfaces are discussed in this review.

Advances in device technology have been accompanied by the development of new types of materials and device fabrication methods. Considering device design, initiated chemical vapor deposition (iCVD) inspires innovation as a platform technology that extends the application range of a material or device. iCVD serves as a versatile tool for surface modification using functional thin film. The building of polymeric thin films from vapor phase monomers is highly desirable for the surface modification of thermally sensitive substrates. The precise control of thin film thicknesses can be achieved using iCVD, creating a conformal coating on nano-, and microstructured substrates such as membranes and microfluidics. iCVD allows for the deposition of polymer thin films of high chemical functionality, and thus, substrate surfaces can be functionalized directly from the iCVD polymer film or can selectively gain functionality through chemical reactions between functional groups on the substrate and other reactive molecules. These beneficial aspects of iCVD can spur breakthroughs in device fabrication based on the deposition of robust and functional polymer thin films. This review describes significant implications of and recent progress made in iCVD-based technologies in three fields: electronic devices, surface engineering, and biomedical applications.

“…We do believe that the inorganic core of our 3D structure provides a high stability. Kim et al prepared a superhydrophobic sponge (totally organic based material) using iCVD, where both 3D porous core structure and coated layer are both organic . Our 3D hybrid structure (PTFE: organic layer and TiO 2 : inorganic skeleton) seems to resist chemical and physical environment better.…”

or partially removed, superhydrophobicity properties vanish easily. Such 2D surfaces provide a metastable superhydrophobic state since the limited entrapped air in such surfaces disappears quickly in contacting with water and the surface gets completely wetted within a short time. In contrast, 3D structures maintain trapped air at the surface and through whole bulk. [7] These kinds of structures may provide a stable and long-running superhydrophobicity since penetrating water will meet continuously with a fresh trapped-air barrier. It is essential to extend the surface topographies responsible for superhydrophobicity into the bulk by creating both roughness and low surface energy to achieve superhydrophobic 3D materials.Herein, a commercially available polyurethane (PU) foam was utilized as the sacrificial hard template to infiltrate TiO 2 nanoparticles in its interstitial pores. By simply burning out PU template and sintering at 850-900 °C, a 3D TiO 2 skeleton (forming inner and outer macropores) was achieved by 2D assembling of TiO 2 nanoparticles through the whole bulk. By combining macrolevel pores and the micro-/nanostructured topography, a 3D high surface roughness was achieved (Figure 1a; Figure S1, Supporting Information). The prepared TiO 2 slurry was also applied to planar quartz substrates by double-doctor blade coating technique to achieve micro-/nanostructured 2D TiO 2 (Figure 1a; Figure S2, Supporting Information). Afterward, initiated chemical vapor deposition (iCVD) was carried out to coat 2D and 3D TiO 2 homogenously with a thin layer of polytetrafluoroethylene (PTFE) while conserving the inner micro-and nanotopography (as shown schematically in Figure 1b). iCVD allows coating various types of substrates varying from simple 2D to complex 3D structures with a high conformity (without altering topographic details of the pristine structure). [8] After coating a thin layer of PTFE, 3D TiO 2 showed an extraordinary superhydrophobicity.3D TiO 2 has a porous structure with the pore size of ≈100-150 µm (Figure 2a) and exhibits approximately the same micro-and nanoscale structures with 2D TiO 2 surface prepared for the comparison by the well-established doctor blade technique. [9] While 2D surface was composed of micro/nano hierarchical porous texture, 3D surface consists additionally macropores (Figure 2a). Clearly micro-and nanoscale roughness was provided through the whole bulk in 3D TiO 2 . Following the iCVD step, we did not observe any significant change in the morphology of both 2D and 3D TiO 2 . This indicates that the deposited PTFE layer was extremely thin and highly conformal. Figure 2b shows the X-ray photoelectron spectroscopy (XPS) survey spectra of the uncoated and coated 3D TiO 2 . Simply Combining hard-templating and infiltration processes, micro-and nanoscale topography induced by 2D assembling of TiO 2 nanoparticles is extended to 3D TiO 2 . By applying an ultrathin and highly conformal polytetrafluoroethylene (PTFE) layer on prepared 3D TiO 2 via initiated chemical vapor deposition (iC...
