The sol–gel process is a wet-chemical technique used for the fabrication of both glassy and ceramic materials. In this process, the sol (or solution) evolves gradually towards the formation of a gel-like network containing both a liquid phase and a solid phase.
Dip coating of inorganic sols (or so-called sol-gel synthesis) is a way of creating thin inorganic or polymeric coatings. In sol-gel synthesis the speed of deposition is an important parameter that affects, for example, layer thickness, density and porosity.
Mechanics of gelation describes processes relevant to sol-gel process. In a static sense, the fundamental difference between a liquid and a solid is that the solid has elastic resistance against a shearing stress while a liquid does not. Thus, a simple liquid will not typically support a transverse acoustic phonon, or shear wave. Gels have been ...
The sol-gel process is a common method of preparing water-repellent glass coating films done with various materials and often resulting in dual-layer films. [7] This process is advantageous for automobile window applications since it works with large, curved safety glasses and allows qualities such as durability and hydrophobicity to be ...
One process for making nanoceramics varies is the sol-gel process, also known as chemical solution deposition. This involves a chemical solution, or the sol, made of nanoparticles in liquid phase and a precursor, usually a gel or polymer, made of molecules immersed in a solvent. The sol and gel are mixed to produce an oxide material which are ...
The Stöber process is a sol-gel approach to preparing monodisperse (uniform) spherical silica (SiO 2 ) materials that was developed by a team led by Werner Stöber and reported in 1968. [ 1 ] The process, an evolution and extension of research described in Gerhard Kolbe's 1956 PhD dissertation, [ 24 ] was an innovative discovery that still has ...

The use of nanoparticles and nanofibers to produce specialized nanofabrics became a subject of interest after the sol-gel [12] and electrospinning [13] techniques were fully developed in the 1980s. [14] Since 2000, dramatic increases in global funding have accelerated research efforts in nanotechnology, including nanofabrics research. [15]
