Description

technical field [0001] The invention relates to the field of capacitor processing, in particular to a conductive polymer material, a preparation method thereof and a capacitor comprising the same. Background technique [0002] A capacitor is a device capable of storing electric charges, which can be formed by two opposing plates, a cathode plate and an anode plate; it can also be formed by inserting an insulating sheet between the two plates. It is one of the most basic and important components in electronic equipment. The output of capacitors accounts for more than 40% of the world's electronic components. Basically, it can be seen in all electronic equipment, as small as U disks and digital cameras, as large as space shuttles and rockets. As one of the most basic electronic components, capacitors are as indispensable to electronic equipment as food is to humans. [0003] Although the capacitor is small, it fully reflects a country's industrial technology capabilities, es...
