PROCESS FOR MAKING HYBRID MICRO-ELECTRODES OF CARBON NANOTUBES-METHYLBENZENEPYRROLE CONDUCTIVE POLYMER TYPE FOR ELECTRO-CHEMICAL DETECTION IN OXIDIZING MEDIUM

The invention relates to a process for making hybrid micro-electrodes of carbon nanotubes-methylbenzenepyrrole conductive polymer type for electro-chemical detection in oxidizing medium. According to the invention, the process consists in manufacturing the nanocarbon electrode by manual screen printing on a ceramic support with pre-depositions of metallic connections with three electrodes, after which the electro-conductive polymer deposition on the nanocarbon electrode is performed by the direct connection of the electrode with 3 connections to the flow cell and to the potentiostat, using methylbenzenepyrrole, at a scanning rate of 30mV/s, effective for carrying out uniform structures of polymeric film, with a complete deposition of 8 successive layers. Invenţia se referă la un procedeu de obţinere a unor microelectrozi hibrizi, de tip nanofibre de carbon-polimer conductiv metilbenzenpirol, pentru detecţie electrochimică în mediu oxidant. Procedeul conform invenţiei constă în realizarea electrodului de nanocarbon, prin serigrafiere manuală a unui suport ceramic, cu predepuneri de conexiuni metalice cu trei electrozi, după care se realizează depunerea de polimer electroconductiv pe electrodul de nanocarbon, prin conectarea directă a electrodului cu 3 conexiuni la celula de flux şi la potenţiostat, folosind metilbenzenpirol, la o viteză de baleiaj de 30 mV/s, eficientă pentru realizarea unor structuri uniforme de film polimeric, cu o depunere completă de 8 straturi succesive.
