Plasma Irradiation to Ionic Liquids using 2.45 GHz Microwave Discharges

抄録

Experiments on plasma irradiation to ionic liquids (ILs) have been initiated. Despite lower density and kinetic energy of ions, discoloration of ILs is still observed. Spectrometric and calorimetric measurements show that once the visible change in color of ILs happens, spectra of both the crystallization temperature and the melting point completely disappear, suggesting decompositions of a part of components of ILs by plasma irradiation.
