An atmospheric pressure glow-discharge plasma in contact with liquid is generated using a capacitively coupled plasma (CCP) method, by which a boundary region between a plasma (gas-phase) and liquid paraffin (liquid-phase), i.e., gas-liquid interface is considered to be important. A stable atmospheric pressure plasma with liquid is achieved by selecting the appropriate mesh electrode and liquid paraffin. In addition, results of optical emission spectroscopy indicate that carbonic species come from paraffin in the interface region of the plasma. This plasma is accordingly expected to promote the use of an attractive plasma process for creating materials encapsulating various elements in liquids.
