Problems solved by technology

However, in the current research, only one or two kinds of inorganic magnetic composites are complexed with a conductive polymer, and the conductive polymers are mostly polyaniline and its homologues, and the modified electrodes are mostly graphite and activated carbon, so many The preparation process of a composite-modified mesh glassy carbon electrode is still lacking in this aspect.
