Przedmiotem zgłoszenia jest sposób otrzymywania ,przedstawionej na rysunku elektrody z przewodzącego włókna kwasu polimlekowego (PLA) lub przewodzącego włókna kwasu polimlekowego (PLA) domieszkowanego grafenem jako warstwy wewnętrznej, polegający na wytworzeniu matrycy wydrukowanej w technologii trójwymiarowej (3D), metodą osadzania topionego materiału (FDM - ang. Fused Deposition Modeling) oraz połączeniu z warstwą zewnętrzną, gdzie warstwą zewnętrzną jest folia nanodiamentowa (NDF), korzystnie domieszkowana borem lub azotem, którą nanosi się bezpośrednio na matrycę wydrukowaną w 3D, a wymagana temperatura matrycy do transferu folii wynosi 150°C - 300°C. Electrode for electrochemical measurements, made of two layers, with one layer made of conductive polylactic acid (PLA) fibre or conductive polylactic acid (PLA) fibre doped with graphene, being a graphene-polymer layer, in which the weight ratio of graphene to PLA was 0.5% to 20% of graphene by weight and 99.5% to 80% of PLA by weight in the same layer of the electrode, and the layer is coated with nanodiamond foil (NDF) or a layer of nanodiamond powder (NDP). The layer of PLA or graphene/PLA is 0.1 to 5 mm thick and is coated with a layer 50 nm to 1500 nm thick being up to 0.1% of the entire electrode weight.
