Dataset for the paper "Barrier Graphene Oxide on a CoCr Alloy via Silane/GO Covalent Bonding and Its Electrochemical Behavior in a Simulated Synovial Fluid Electrolyte"

[EN] This is the experimental dataset used in the paper “Barrier Graphene Oxide on a CoCr Alloy via Silane/GO Covalent Bonding and Its Electrochemical Behavior in a Simulated Synovial Fluid Electrolyte". The article includes the experimental procedure carried out for the deposition of graphene oxide on CoCr surfaces: CoCr was hydroxylated through alkalization in NaOH 5 M for 2 h, (sample named CoCr-OH). Subsequently, silanization was carried out using APTES. APTES was pre-mixed at 2% vol in isopropanol-water (200:1 v/v) and stirred for 1 h. After this, CoCr-OH samples were immersed in the APTES solution at room temperature for 1 min. The silane-coated samples were kept under curing conditions at 45 °C (CoCr-OH-Si45 sample) and 75 °C (CoCr-OH-Si75 sample) for 24 h and 30 min, respectively. Finally, CoCr-OH-Si45 and CoCr-OH-Si75 surfaces were immersed in 4 g/L GO aqueous suspension at 60 °C for 12 h and 24 h to obtain CoCr-OH-Si45-GO12h, CoCr-OH-Si75-GO12h and CoCr-OH-Si45-GO24h, and CoCr-OH-Si75-GO24h. This data set includes the results of the electrochemical impedance data obtained for each CoCr surface: CoCr (CoCr, CoCr-OH, CoCr-OHSi45, CoCr-OH-Si75 CoCr-OH-Si45-GO12h, CoCr-OH-Si75-GO12h y CoCr-OH-Si45-GO24h, y CoCr-OH-Si75-GO24h, immersed in 3 g/L Hyaluronic acid solution for 7 days.
