tailieunhanh - Acetylcholinesterase sensor based on PANi/rGO film electrochemically grown on screen-printed electrodes

In this work, the polyaniline/reduced graphene oxide (PANi/rGO) bilayer was directly electrodeposited on carbon screen-printed electrodes (SPE). Some details in growth of PANi/rGO bilayer were revealed from cyclic voltammograms and X-ray photoelectron spectra. The growth of stacked rGO film at high compactness on the electrode surface is mainly accompanied with reduction of epoxy functional groups at basal planes of graphitic flakes. The asgrown rGO layer with abundent hydroxyl functional groups at basal planes is preferable to attract intrinsic fibrillar-like PANi polymer chains in protonated aqueous media. |
