The present invention relates to a method for preparing high performance polymer-based conductive composites by space-limited micro-nano precision assembly method, which belongs to the technical field of composite material preparation; including the following steps: (1) through blending the conductive filler and the polymer matrix which are added to the blending equipment, homogeneous polymer/conductive filler material system is obtained; (2) add the homogeneous material system to the mold composed of two flat plates, and let the homogeneous blend gets plane limited compression by means of mechanical compression; (3) making use of the micro-nano structure array set on the compression template to further compact the filler on the network and conducting 'array anchorage', to realize the micro-nano precision assembly of network and obtain the composite material with excellent performance, which has a continuous and tight conductive network, and has excellent tensile properties, flexibility and thermal stability.
