Resumen:
In this work, we report a simple method for the fabrication of regular conducting
polyanliline periodic arrays on large areas of glass or gold substrates using
direct laser interference patterning. Additionally, by controlling the laser intensity it is
possible to precisely tune the width of the periodic arrays and consequently the electrical
resistance of the polyanliline strips. The periodic arrays were characterized using
scanning electron microscopy, white light interferometry and cyclic voltametry. The
great importance of the method reported lies both in its versatility and the ability to
control the properties of the modified polymer electrodes with high precision. This is
important for prospective applications such as electrochemical sensors.
