Abstract:
1. A method of synthesizing hollow silica from sodium silicate for reflective adiabatic materials, the method comprising: (A) fabricating a polystyrene organic template having an average particle size of 1 μm to 3 μm from polystyrene latex after fabricating the polystyrene latex by mixing styrene monomer, 2-(methacryloyl)ethyltrimethylammonium chloride (MTC), 2,2′-azoisobutyronitrile (AIBN), polyvinylpyrrolidone (PVP), ethanol, and water (H (B) cleaning the polystyrene organic template; (C) exchanging media by using a water-based medium, introducing the cleaned polystyrene organic template and sodium silicate, and preparing a silica-coated organic template by performing an acidic hydrolysis reaction; and (D) cleaning the silica-coated organic template included in the water-based medium by using water.
