▎ 摘  要

NOVELTY - Method for dispersing (1) graphitic nanomaterials involves injecting (2) entity comprising graphitic nanomaterial and host material, and driving force into supersonic dispersion reactor to generate multiphase mixture, providing (3) compression and increasing speed of the mixture to generate nanobubbles, and decelerating (4) speed of the mixture through supersonic threshold to generate high intensity cavitation leading to effective dispersion of the graphitic nanomaterials into host material. The entity and driving force merge into highly compressible multiphase mixture. USE - Method for dispersing graphitic nanomaterials used for producing graphene nanocomposites using shock waves with extremely high specific energy. ADVANTAGE - The method enables facile and economical dispersion of graphitic nanomaterials, where the suspension is stable for long period of time using multiphase fluid dynamic technique in industrial scale. DETAILED DESCRIPTION - Method for dispersing graphitic nanomaterials using multiphase fluid dynamic dispersion, where the flowing multiphase working stream converts potential energy of the stream into high energy cavitation nanobubbles that when collapse generates supersonic shock interactions involves injecting entity comprising graphitic nanomaterial and host material, and driving force into supersonic dispersion reactor to generate multiphase mixture, providing compression to multiphase mixture and increasing the speed of the multiphase mixture to supersonic range and subsequently condensing the driving force in the multiphase mixture to generate nanobubbles, and decelerating the speed of the multiphase mixture through supersonic threshold to collapse nanobubbles and generate high intensity cavitation leading to effective dispersion of the graphitic nanomaterials into host material. The entity and driving force merge into highly compressible multiphase mixture. An INDEPENDENT CLAIM is included for system for dispersing graphitic nanomaterial by supersonic shock waves with extremely high specific energy, which has mixing zone where the injected streams merge into highly compressible multiphase mixture, narrowing inlet valve zone for compressing and increasing speed of the mixture to supersonic speed, nanobubbles generation zone where the injected streams condense in the mixture and generate localized heat and nanobubbles, deceleration zone where the nanobubbles collapse and generate high intensity cavitation, and discharging zone for discharging the dispersion with predefined discharge thrust to enhance the dispersion of graphitic nanomaterial.
