Mechanically durable superhydrophobic surfaces.
Development of durable non-wetting surfaces is hindered by the fragility of the microscopic roughness features that are necessary for superhydrophobicity. Mechanical wear on superhydrophobic surfaces usually shows as increased sticking of water, leading to loss of non-wettability. Increased wear resistance has been demonstrated by exploiting hierarchical roughness where nanoscale roughness is p...
متن کاملOrganic Solvent-Free Fabrication of Durable and Multifunctional Superhydrophobic Paper from Waterborne Fluorinated Cellulose Nanofiber Building Blocks.
In view of a great demand for paper-based technologies, nonwettable fibrous substrates with excellent durability have drawn much attention in recent years. In this context, the use of cellulose nanofibers (CNFs), the smallest unit of cellulosic substrates (5-20 nm wide and 500 nm to several microns in length), to design waterproof paper can be an economical and smart approach. In this study, an...
متن کاملMagnetic, superhydrophobic and durable silicone sponges and their applications in removal of organic pollutants from water.
Porous silicone sponges are fabricated by polymerization of organosilanes in the presence of Fe3O4@silica nanoparticles. The sponges feature fast magnetic responsivity, superhydrophobicity/superoleophilicity, high compressibility and stability. The sponges can selectively absorb floating oils on a water surface, heavy oils under water and even emulsified oils.
متن کاملInvestigating the factors affecting the Qanat discharge as a method for sustainable harvesting water from underground water resources
Qanat is a technique for obtaining water and transferring it for various uses. Due to the widespread arid and semi-arid areas in Iran, Qanat is the most sustainable method to obtain underground water. Considering the role of the Qanat in providing water to dry areas in the current situation of the country, where the issue of water shortage and water resources management is very important. Due t...
متن کاملToward a durable superhydrophobic aluminum surface by etching and ZnO nanoparticle deposition.
Fabrication of suitable roughness is a fundamental step for acquiring superhydrophobic surfaces. For this purpose, a deposition of ZnO nanoparticles on Al surface was carried out by simple immersion and ultrasound approaches. Then, surface energy reduction was performed using stearic acid (STA) ethanol solution for both methods. The results demonstrated that ultrasound would lead to more stable...
