In this study, highly conductive and polarizable electrode material was tried to be fabricated by improving the conductivity of diamond like carbon films using the impurity (nitrogen atoms) doping methods and the novel electrochemical device that combines the specificity of the nano-structure and the superior electrochemical properties of conductive DLC films was tried to be developed.(1) Establishment of the deposition methods of highly conductive DLC films and its electrochemical properties. The heavily nitrogen doped DLC films was successfully fabricated by adding nitrogen atoms in the DLC thin films that was synthesized using plasma CVD methods. The resistivity of DLC films could be controlled by changing the RF plasma power during the CVD synthesis. The resulting highly conductive DLC films show the wide working potential range (ca. 4.0 V) in 0.1 M H_2SO_4, that is in the same range with that fir the boron-doped diamond electrodes (ca. 3.5 V). Therefore, it turned out that highly … More conductive DLC films works as an ideal polarizable electrode material with good response fix electrochemical reaction of typical redox species like Fe(CN)_6^<〓>. Moreover, the highly conductive DLC films show high corrosion resistance for the electrochemical treatment (long term potential cycling from -0.65 to 1.3 V) in strong acid solution (0.1M NaF in 1M HNO_3, indicating that the DLC films was highly stable fir the electrochemical application in extreme environmental conditions.(2) Fabrication of the conductive DLC thorough-hole membrane and the development of the switching ion permeation filtersConductive DLC thorough-hole membrane was fabricated by depositing DLC films with thickness of by nano meters on the surface of porous alumina with highly ordered nano-pore allays. By using the conductive nano-porous membrane with 25 nm of pore diameter as a filter material, the permeability of cation was suppressed by applying positive potential on conductive DLC membrane and the permeability of anion was suppressed by applying negative potential. For the mixed media of cation and anion, the selective permeability for cation could be achieved by applying negative potential Therefore the switching filters that can arbitrarily control the ion permeability by the size of pore diameters and the membrane potential could be successfully realized.
