摘要： Disclosed is a plasma surface treatment apparatus for conductive powder. The plasma surface treatment apparatus for conductive powder comprises: a reaction chamber including a linear gas inlet at the lower end thereof and a gas outlet at the upper end thereof, and having a vertical cross section that is funnel-shaped; and a plasma jet generation device that is located below the linear gas inlet and is configured to discharge a plasma jet into the reaction chamber from below in an upward direction through the linear gas inlet, wherein powder is accommodated in the reaction chamber and is treated by plasma while buoyed by the plasma jet.

摘要： The present invention relates to a method of improving aqueous dispersibility of conductive carbon powders, and to a method of preparing a colloid solution of conductive carbon powders. The present invention comprises a step of exposing conductive carbon powders to a plasma jet or reacting same with a plasma-treated reaction gas, wherein the step is characterized by reacting the plasma-treated reaction gas (ionized gas) with the conductive carbon powders, and accordingly by using plasma, the aqueous dispersibility of the conductive carbon powders may be improved in a convenient manner.
