Abstract: PURPOSE: A method for preparing silica nanoparticles imparting thermal stability and mechanical strength by encapsulating aromatic oil with silica. CONSTITUTION: A method for preparing silica nanoparticles comprises the steps of: (i) forming an emulsion solution by adding surfactant, cosurfactant and aromatic oil to water; and (ii) adding a silica precursor to an emulsion solution to obtain silica nanoparticles. The surfactant is added in the amount of 1-4 weight% based on water. The cosurfactant is added in the amount of 1-10 volume % based on water.
