Latest Patents

Chang-Kook Hong holds a patent for a method for producing sheets that include fibrous aerogel. The patent outlines a detailed process that involves several steps: first, gelling a water glass solution in a mixture of alcohol and water to prepare a wet gel. Next, the surface of the wet gel is hydrophobically modified using a non-polar organic solvent, an organosilane compound, and alcohol. Following this, the hydrophobically modified silica gel and a polymer are dissolved in an aprotic organic solvent to create an electrospinning solution. Finally, the electrospinning solution is processed to produce a fiber web that includes a silica aerogel, resulting in a sheet where a polymer and silica aerogel coexist in fiber form. This innovative method has the potential to enhance the properties of materials used in various applications.
