Fence type ionic current rectifier

The utility model relates to the field of nano-fluid, and particularly discloses a fence type ion current rectifier, which comprises a first ion straight channel, a second ion straight channel and a fence type nano-channel, and the fence type nano-channel consists of four parallel long conical nano-channels. According to the utility model, the long conical nano-channel is designed, when positive and negative voltages are applied to the first ion straight channel, ions in the nano-channel are accumulated or lost due to the ion selectivity of the long conical nano-channel, and finally, the conductivity of the nano-channel and the ion current in the channel are changed. The ion rectification device has the main advantages that the whole ion rectification process is realized only by applying an external electric field, and the rectification efficiency is improved by the long conical structure, so that the ion current in the nano-channel is more stable. 本实用新型涉及纳流体领域，具体公开了一种栅栏式离子电流整流器，包括第一离子直通道、第二离子直通道、栅栏式纳米通道，栅栏式纳
