栗田製作所 List of Products and Services

Kurita Manufacturing Co., Ltd.'s "Liquid Plasma Technology" is a technique that generates corona discharge and glow discharge in liquid rather than in a vacuum or atmosphere. By utilizing reactive species (H radicals, OH radicals) and ultraviolet light generated from the plasma, it enables high-speed processing of targets at the gas-liquid interface. By treating CNTs and modifying their surface with hydrophilic groups, it can improve their dispersibility in water. When treating a gold chloride aqueous solution, gold nanoparticles can be synthesized through a reduction reaction. 【Contents of Liquid Plasma Technology】 ■ CNT Dispersion ■ Nanoparticle Synthesis ■ Decolorization ■ Development of Multi-channel Systems For more details, please refer to the catalog or feel free to contact us.

The liquid plasma generation device is compact and allows for easy experimentation with solution plasma. It generates plasma in liquid, enabling the synthesis of new materials and the creation of processing environments, representing a new plasma application technology. Various effects are demonstrated, such as the generation of nanoparticles and the imparting of water solubility to carbon nanotubes. Discharge is sustained through secondary electrons from the liquid and the coupling reactions between plasma and liquid. Additionally, because the discharge occurs in liquid, it is also possible to utilize the chemical reactivity of the liquid used. As it employs pulsed glow discharge, treatment can be performed at low temperatures. Compared to arc discharge, electrode damage is significantly reduced, allowing for prolonged operation. The generation of solution plasma uses a pulsed power supply, and by adjusting the conductivity of the liquid and the distance between electrodes, solution plasma can be generated with very low energy (a few hundred watts).
