Method for antiaglomeration treatment of nanomaterials in colloidal suspensions using plasma generated in the liquid phase

摘要

Process for the anti-agglomeration treatment of nanomaterials by interaction of their suspension in an aqueous solution, a solution of an organic or inorganic substance, or a combination of these solutions with plasma generated either directly in the liquid phase or by interaction with plasma blown into this phase. Any plasma generating system at atmospheric or near atmospheric pressure, or systems for generating plasma directly in the liquid phase by a pulsed or continuous mode system can be used to generate the plasma. These parameters thus determine the conductivity requirements of the nanoparticle suspension ranging from 0 mS / m to 0.200 S / m. The pH of the suspension is limited by the insolubility of the nanoparticles themselves. Both inorganic and organic nanomaterials can be treated, and the treatment has a long-term effect.
