Study of Superhydrophobic Biomimetic Surfaces
The surface properties of materials are very important, and researchers attempt all sorts of methods to obtain materials surfaces with required properties. With the development of bionic engineering, researchers are paying an increasing attention to biological surface in order to understand how the nature can solve engineering problems. The extensive investigations on biological surfaces have revealed that these surfaces have many unusual properties. The “lotus-effect” is a typical phenomenon that the natural surface structure as blueprint is used to designRead More …
Superhydrophobic Surface Can Be Prepared by Two Methods
People know the self-cleaning lotus effect for many years, but can not make the material as the lotus leaf surfaces. By nature, the typical superhydrophobic surface – study found that lotus leaf, constructed with a special geometry of roughness in the low surface energy solid surface plays an important role on superhydrophobic.Based on these principles, the scientists began to mimic this surface. Now, research on rough superhydrophobic surface has been quite a lot of coverage. In general, the superhydrophobic surfaceRead More …
Self-cleaning Effect of Super Hydrophobic Surface
Wettability is an important feature of the solid surface, which is determined by the chemical composition and morphology of the surface. Super-hydrophilic and super hydrophobic surface characteristics are the main contents of invasive studies. The superhydrophobic (water-repellent) surface generally refers to the surface that the contact angle between water and surface is greater than 150 degrees. That people know superhydrophobic surface is mainly from plant leaves – lotus leaf surface, “self-cleaning” phenomenon. For example, water droplets can roll to rollRead More …
The Principle of Hydrophobic/Super Hydrophobic Coatings
Conventional sol-gel coatings were prepared using MTMOS and TEOS as silane precursors to form a smooth, clear and dense organic/inorganic network on an aluminum alloy substrate. Such coatings are known to have excellent adhesion due to their ability to form Al-O-Si linkages at the coating/substrate interface.Sample-II in this study represents such a conventional sol-gel coating. In order to reduce surface energy, and hence increase hydrophobicity, we incorporated an organo-silane containing a fluorooctyl chain, in addition to MTMOS and TEOS (sampleRead More …
Super hydrophobic surfaces is created by Super hydrophobic coatings
Super-hydrophobic coatings can be made from many different materials. The following are known possible bases for the coating: Manganese oxide polystyrene (MnO2/PS) nano-composite Zinc oxide polystyrene (ZnO/PS) nano-composite Precipitated calcium carbonate Carbon nano-tube structures Silica nano-coating Super-hydrophobic coatings are used to create super hydrophobic surfaces. When water or a water based substance comes into contact with these coated surfaces, the water or substance will “run off” of the surface because of the hydrophobic characteristics of the coating. Neverwet is aRead More …
Future development prospects of hydrophobic paint
Hydrophobic paint often refer to a class of low surface energy coatings where the static water contact angle θ of the coating on a smooth surface is greater than 90°, whereas superhydrophobic paint are a new type of coating with special surface properties, meaning water contact with a solid coating. The angle is greater than 150° and often means that the water contact angle lag is less than 5°. From 2017 to 2022, the hydrophobic paint market will grow atRead More …
