This paper describes the specific features of supercritical hydrothermal synthesis method for organic modified nanoparticles synthesis and their applications for hybrid materials with polymers. Under the supercritical state, water-organic molecules-inorganic precursors form a homogeneous phase with high concentration, and the water molecule works as an acid or base catalyst. This leads to form optimum conditions for synthesizing organic modified nanoparticles with high concentrations. Also, this method can control the exposed surface, which leads to fabricate a new active catalyst. The formed nanoparticles can be mixed with organic solvents or with polymers, and thus, this method can fabricate new hybrid polymers.
