Latest Patents

Bok Yeop Ahn holds a patent for a "Process for preparing silica microcapsules." This invention involves a method that includes dissolving tetraethyl orthosilicate (TEOS) in an aqueous solution with a hydrolysis catalyst. The process aims to control the degree of hydrolysis and enhance the hydrophilicity or lipophilicity of the microcapsules. By adding a core material and aminopropyltrialkoxysilane (APS) as a gelling agent, Ahn's method allows for the emulsification and dispersion of the solution. This results in microcapsules that are coated with a silica shell through a sol-gel reaction. Notably, this process reduces environmental pollution compared to traditional methods that utilize alkali gelling agents, making it suitable for both organic and inorganic core materials.
