| Résumé |
|
The surface of screen printed carbon electrode (SPCE) with partially blocked surface was treated by argon plasma in order to improve their electrochemical performances. The argon plasma was generated by a radio-frequency electrical discharge at low pressure. Study of the electrode surface by scanning electronic microscopy (SEM) has revealed a significant change of the morphology of the SPCE surface after plasma pre-treatment. The electrochemical reactivity of the SPCEs was characterized using cyclic voltammetry. A drastic enhancement of the SPCEs electrochemical reactivity was highlighted after plasma pre-treatment. The effect of biasing the SPCE surface during the plasma treatment has been investigated and showed that depending on the nature of plasma treatment, the same electrode could show a radial or planar diffusion.
