摘要

We have reported fabrication of the films with tunable and controllable morphologies and structures, based on electrophoretic deposition (EPD) in the Ag colloidal solution, produced by laser ablation (LA) of a Ag flake in deionized water, under a constant current deposition mode, and found significant crystal growth during EPD. A mechanism was presented, on the basis of our experimental results, to describe formation of the regularly shaped single crystal, which was mainly attributed to the crystal growth induced by preferential oriented connection of the nanoparticles (NPs) in the colloidal solution and/or on the substrate during EPD. Recently, Kvitek and Hrbac oppugned our preferential oriented connection mechanism, based on the "unreasonable value of surface potential", and presented chemical mechanism with two possible processes, (i) anodic dissolution of silver NPs and subsequent reduction at cathode and (ii) direct water electrolysis induced oxidation and back-reduction of primary silver NPs. They believed that the proposed chemical mechanism was more probable than the mechanism of oriented connection. Here are some replies.
