WebIf water is used as the medium of dispersion, then such sols are also called hydrophilic sols. Examples of lyophilic sols can be the colloidal solution of starch, gum, gelatin, etc. …
WebFor example, iron (III) hydroxide forms a colloid because an excess of iron (III) ion is present on the surface, given each crystal an excess of positive charge. These positively charged crystals repel one another, so aggregation to large particles is prevented. Web28 sep. 2024 · For example, incorporating nanostructures in the TiO 2 coating can make it hydrophilic and oleophobic, thus enhancing the absorption of water while improving the surface resistance to oil. Thereby, these TiO 2 -based surface modifications can improve the efficiency of the oil/water separating filter.
WebThis process technology is much more complex than for activating and degreasing. It is used for example to produce barrier coats in fuel tanks, scratch-resistant coats on headlights and CDs, PTFE-like coatings, hydrophobic coats, etc. There are three coating processes that have established themselves on an industrial scale: WebIf water is used as the dispersion medium, lyophilic sols are called hydrophilic sols. Starch, gum, gelatin, egg albumin etc. are examples of lyophilic sols. Starch Sol Starch forms lyophilic sol when water is used as the dispersion medium. The formation of sol is accelerated by heating. Starch sol can be prepared by heating it and water at 100 °C.
