Simple fabrication of active electrodes using direct laser transference

摘要: Direct laser transference (DLT) method is applied to obtain electrodes modified with thin films of conducting polymers (CPs) or catalytic metals. A short (6–10 ns) pulse light (second harmonic Nd-YAG Laser, λ = 532 nm) shined on the backside a (<200 nm) film material be transferred, which deposited transparent substrate. The illuminated region heats up and (conducting polymer metal) thermally transferred solid target placed at distance in air. In that ways, CPs are onto polypropylene, glass, indium doped tin oxide (ITO), glassy carbon gold films. same manner, electrocatalytic metals (platinum gold) conductive substrates (glassy ITO glass). have been characterized by scanning electron microscopy, cyclic voltammetry, atomic force UV-visible Fourier Transform Infrared spectroscopies. chemical, electrical redox properties polymeric materials remain unaltered after transfer. Moreover, CP multilayers can built applying DLT several times Besides polyaniline, it shown also possible transfer functionalized polyanilines. electrode Pt shows activity toward methanol oxidation while ferricyanide quasireversible behavior Au. simple fast, works air without complex environmental conditions produce active different materials. It only requires pulsed high power laser, presently available low cost, substrata as source. this way seems general straightforward build technological devices based and/or including for direct fuel cells sensors.
