“…A large class of natural or synthetic zeolites (i.e., A, X, Y, SAPO, ALPO, …), were used as coating material on several substrates to obtain 'smart' layers (that respond selectively to the environment) able to offer a suitable functional action. Zeolite coating technology was applied effectively in several industrial purposes, e.g., catalysis processes [40,41], optic [42,43], adsorption [44,45], sensing [46,47] applications.…”

Research activity concerning nanoporous zeolites has grown considerably in recent decades. The structural porosity of zeolites provides versatile functional properties such as molecular selectivity, ion and molecule storage capacity, high surface area, and pore volume which combined with excellent thermal and chemical stability can extend its application fields in several industrial sectors. In such a context, anti-corrosion zeolite coatings are an emerging technology able to offer a reliable high performing and environmental friendly alternative to conventional chromate-based protective coatings. In this article, a focused overview on anti-corrosion performances of sol-gel composite zeolite coatings is provided. The topic of this review is addressed to assess the barrier and self-healing properties of composite zeolite coating. Based on results available in the literature, a property–structure relationship of this class of composites is proposed summarizing, furthermore, the competing anti-corrosion active and passive protective mechanisms involved during coating degradation. Eventually, a brief summary and a future trend evaluation is also reported.

“…Moreover, recent literature evidenced that zeolite, due to its hydrophilic properties, transparency and scratch resistance, is a promising candidate for AR coating. However, one of the key issues is the deposition process which often involves in situ and seeded growth, requiring synthesis of the layer using chemical solutions (most of them are highly basic), hindering the deposition of silica-based substrate [ 53 , 54 ]. Moreover, the calcination process at temperatures higher than 400 °C for different hours is harmful for the PV cell [ 39 , 53 , 54 ].…”

Anti-Reflective Zeolite Coating for Implantable Bioelectronic Devices

Since sunlight is one of the most easily available and clean energy supplies, solar cell development and the improvement of its conversion efficiency represent a highly interesting topic. Superficial light reflection is one of the limiting factors of the photovoltaic cells (PV) efficiency. To this end, interfacial layer with anti-reflective properties reduces this phenomenon, improving the energy potentially available for transduction. Nanoporous materials, because of the correlation between the refractive index and the porosity, allow low reflection, improving light transmission through the coating. In this work, anti-reflective coatings (ARCs) deposited on commercial PV cells, which were fabricated using two different Linde Type A (LTA) zeolites (type 3A and 4A), have been investigated. The proposed technique allows an easier deposition of a zeolite-based mixture, avoiding the use of chemicals and elevated temperature calcination processes. Results using radiation in the range 470–610 nm evidenced substantial enhancement of the fill factor, with maximum achieved values of over 40%. At 590 and 610 nm, which are the most interesting bands for implantable devices, FF is improved, with a maximum of 22% and 10%, respectively. ARCs differences are mostly related to the morphology of the zeolite powder used, which resulted in thicker and rougher coatings using zeolite 3A. The proposed approach allows a simple and reliable deposition technique, which can be of interest for implantable medical devices.

“…Qing et al developed a robust superhydrophobic surface using sandpaper as a template to lock in the fluorinated inorganic/organic film, which demonstrated exceptional mechanical robustness, good pressure stability, and repellency to hot water [77]. Zhang et al prepared a zeolite antireflective (ZAR) coating via the layer-by-layer (LBL) method [78]; they created micro and macroporous structures to realize antireflective property. Moreover, this coating revealed a transparent superhydrophobicity after being grafted with 1H,1H,2H,2H-perfluorooctyltriethoxysilane (POTS).…”

Superhydrophobic surfaces have drawn attention from scientists and engineers because of their extreme water repellency. More interestingly, these surfaces have also demonstrated an infinite influence on civil engineering materials. In this feature article, the history of wettability theory is described firstly. The approaches to construct hierarchical micro/nanostructures such as chemical vapor deposition (CVD), electrochemical, etching, and flame synthesis methods are introduced. Then, the advantages and limitations of each method are discussed. Furthermore, the recent progress of superhydrophobicity applied on civil engineering materials and its applications are summarized. Finally, the obstacles and prospects of superhydrophobic civil engineering materials are stated and expected. This review should be of interest to scientists and civil engineers who are interested in superhydrophobic surfaces and novel civil engineering materials.
