Novel conducting polymer modified 3D printing electrode and preparation method and application thereof

The invention relates to a novel conductive polymer modified 3D printing electrode and a preparation method and application thereof, and belongs to the technical field of preparation of 3D printing electrodes. The preparation method mainly comprises the following steps: stirring an SMS solution (beta-cyclodextrin (beta-CD) and citric acid are subjected to ultrasonic dispersion in water), a polymer solution (a polyvinyl alcohol (PVA) aqueous solution as a polymer network and glutaraldehyde (50% GA) as a cross-linking agent) and a poly (3, 4-dioxoethyl thiophene-poly (p-styrenesulfonic acid) (PEDOT: PSS) aqueous solution to form an SACP precursor solution; the novel conductive polymer modified 3D printing electrode is formed by dropwise adding the conductive polymer to the surface of a gold modified 3D printing electrode (Au at 3DE) through a drop casting method, the preparation method is simple in preparation process and easy to operate, and the prepared conductive polymer modified 3D printing electrode has th
