Nano and micro level surface morphology is a determining factor for its mechanical, chemical, wetting and physical properties. Traditional methods of morphology management, in particular lithography and chemical etching, have a number of disadvantages: low processing speed and process control, insufficient reproducibility over large areas. Among the new promising methods of surface functionalization of materials are technologies of laser-nanostructuring. They allow a controlled change in the optical, mechanical and chemical properties of many materials, which is often impossible using "non-laser" technologies [1].
This work provides a review of different laser-based methods which have been used in the synthesis and fabrication of nanostructured materials and its electrochemical properties, including our recent achievement related to the creation and electrochemical investigation of self-organized periodic nanostructures on the surface of different materials, known as laser-induced periodic surface structures.
The analysis of dependence of physicochemical properties of laser-based Nanostructured materials versus the parameters of laser treatment, material properties, parameters of the surface modification of the electrode(substrate), will identify significant factors influencing the fabrication technology of laser-nanostructured electrodes/substrates with controlled physicochemical properties of the surface [1, 2].
