NOVELTY - Synthesizing three-dimensional electrode homogeneous polypyrrole nanowire array based on internal filtration flow comprises (a) choosing a three-dimensional material as electrode to build internal filtration synthesis device, pumping the synthetic liquid from bottom to top into the electrode to filter the synthesis device, and forming a loop, connecting the anode and the first cathode of the device to the anode and cathode of the power supply respectively, starting the power supply, and reacting for 5-10 minutes; (b) changing the direction of water flow and change the position of the cathode, pumping the synthetic liquid from top to bottom into the electrode to filter the synthesis device, forming a loop, connecting the second cathode of the device to the negative pole of the power supply, starting the power supply, reacting for 5-10 minutes, and performing the above adjustments back and forth; and (c) stopping the device, taking out the anode material of the device. USE - The method is useful for synthesizing three-dimensional electrode homogeneous polypyrrole nanowire array based on internal filtration flow. ADVANTAGE - The method is simple and easy to control, and is suitable for generating homogeneous polypyrrole nanowire arrays on surface and inside of three-dimensional porous materials, and improves the application performance of polypyrrole nanowire.
