Processes and apparatus for preparing ionic self-assembly films

The invention is a process and device for ion self-assembly film, which mainly uses electrostatic attraction to assemble the polyelectrolyte and/or charge nano particle onto the base pieces, thus forms the nano structure functional film. The method immerses the base piece on which there has negative charges into the movable container, the positive ion is absorbed onto the surface of the base piece, it drives the worm through link, and drives the shaft to rotate, it also can be elevated freely, there has a clamp below the gear, and the clamp clamps the film plating pieces. The operation is convenient, the performance is reliable, and the efficiency is high.
