PROCESS FOR PREPARING FLUORINATED, INORGANIC HOLLOW NANOSPHERES

摘要

The disclosure provides a process for preparing a fluorinated silica hollow nanosphere comprising: providing a mixture comprising water, at least one non-reactive solvent; at least one fluorosilane, at least one solvent based silica precursor, and at least one surfactant; shearing the components of the mixture with high shear energy at an energy density of at least 10^6 J/m^3 to form a mini-emulsion; and initiating a one-step sol-gel reaction forming fluorinated hollow silica nanospheres having a particle size of less than about 400nm, more typically about 20 nm to about 400nm.
