The utility model discloses an antifouling surface layer structure of super thin drag reduction with retention layer self -repairing function, including solid, perforated plate, covering and the fluidpressure device who needs the drag reduction, many pore plate device are the cavity in thereby the solid surface outside that needs the drag reduction forms, and the outside parcel of perforated plate has the covering of a plurality of nanometer through -holes, fluid pressure device and cavity intercommunication, fluid pressure device injects the fluid into the cavity intracavity, and the fluid that injects the cavity intracavity into flows past the perforated plate by the cavity under the effect of pressure differential, pack a plurality of nanometer through -holes of full covering, forms the fluid retention layer covering the skin external side, this fluid retention layer can be under the fluidic pressure differential effect of cavity intracavity therefrom the additional fluid of cavityrecover initial condition
