Synthesis of shape-controlled hollow silica nanostructures with a simple soft-templating method and their application as superhydrophobic antireflective coatings with ultralow refractive indices

Abrasion Resistance of Superhydrophobic Coatings on Aluminum Using PDMS/SiO2

“…These functionalities include self-cleaning [1], anti-icing [2], anti-corrosion [3], and anti-biofouling [4] in addition to the native features of aluminum metal such as lightweight and commendable ductility. A wide variety of fabrication techniques are available for the creation of such coatings, which includes but is not limited to the template method [5], chemical etching [6], electro-spinning [7], chemical vapor deposition [8], self-assembled monolayers [9], and nanocomposites [10][11][12]. The two governing factors for developing a superhydrophobic coating are its surface chemistry (low surface free energy) and surface morphology (nano/microscale roughness) [13][14][15].…”

Sol–gel preparation of moisture-resistant antireflective coatings from novel hollow silica nanoparticles

“…HSNs were prepared by the modified Stöber method [23,28]. Typically, at room temperature, 0.15 g PAA dissolved in 7 mL of ammonia hydroxide was mixed with 180 mL of absolute ethanol in a 250-mL glass conical flask, followed by a mixture of MTES and TEOS being injected within 5 h at a time interval of 1 h under vigorous magnetic stirring at 30°C.…”
