FIBROUS AEROGEL SHEET AND PREPARATION METHOD THEROF

摘要

PURPOSE: A method for fabricating a sheet containing silica aerogel is provided to be effectively applied to fields needing adsorption and insulation. CONSTITUTION: A method for fabricating a sheet containing silica aerogel comprises: a step of gelating a water glass solution in a mixture solution of alcohol/water to prepare a wetting gel; a step of modifying the surface of the wetting gel into hydrophobicity using non-polar organic solvent, organic silane compounds, and alcohol; a step of dissolving silica hydrophobic gel and polymer in an aprotic organic solvent to prepare an electrospinning solution; and a step of electrospinning the electrospinning solution to prepare the sheet of fiber web form.
