PROCESS FOR THE SUPERFICIAL MODIFICATION OF INORGANIC NANOPARTICLES WITH COMPOUNDS OF THE SPIROORTHOCARBONATE-TYPE USING ULTRASOUND.

摘要

The present invention refers to a process for the superficial modification of inorganic matter, specially metallic or metallic oxide nanoparticles with compounds of the spiroorthocarbonate-type compounds with alcohol functionality which present compatibility with said nanoparticles, so that when the polymerization is performed, the material is provided with antishrinking or volume expanding properties, once the material is processed for any desired application. The superficial modifiers used for the present invention are the spiroorthocarbonate mono and difunctional alcohol, SOC DIOL and HSOC OL. The ultrasound induction at a predetermined time depends on the characteristics to be obtained in the final product, allowing the nanoparticles to have a better dispersion when these are incorporated in any compound.
