In the last part, electrochemical features of BDD-PM have been assessed in a preliminary study. Prior to characterizing the electrochemical properties of the diamondmembrane, a suitableway to connect the highest number of diamond fibers had to be found. We used e-beam evaporation to deposit 1 μm of titanium through a physical mask and obtained a 2 mm edge ring-shaped contact geometry. Before evaporation, the membrane was photochemically oxidized in order to give the material a hydrophilic behavior and enhance water diffusion. The process has been detailed in the Experimental section. Before the oxidation, the hydrophobic character of the hydrogenated diamond membrane is illustrated through the water droplet angle depicted in Fig. 4c. After oxidation, the high hydrophilic character of themembrane does not allow water droplet formation anymore.
