Abstract
Using polyaniline as the modification material, copper was loaded into the structure of polyaniline, and its structure and morphology were characterized to prove the successful preparation of polyaniline/copper composite material. The internal structure of the substrate, polyaniline, polyaniline/copper and working electrode was characterized by SEM. The results showed that the prepared composite material had been fully loaded on the nickel foam. The three-dimensional porous structure of nickel foam improves the charge transfer efficiency, provides more contact sites for detecting hydrogen peroxide and increases the specific surface area of the electrode. Acrylamide was selected as the main component of the electrolyte gel, and a flexible hydrogel with good conductivity and transparency was obtained by adding other substances. Nickel foam was used as the base material and then soaked in the composite material solution to obtain the working electrode. An electrochemical workstation was used to test the electrochemical performance of the sensor. The prepared electrochemical sensor has a good response to hydrogen peroxide. When the amount of polyaniline is 0.3 g, the sensor has the best detection effect. When sulfonic acid is added to the electrolyte gel, the sensor has a more obvious current response to hydrogen peroxide.
