The invention relates to a preparation method for reactive extrusion of a conducting polymer nanocomposite. The conducting polymer nanocomposite is prepared from polyamides, second component polymers and conducting nanofiller. The preparation method for reactive extrusion of the conducting polymer nanocomposite comprises pretreatment of raw materials, reactive extrusion of anionic ring-opening polymerization of lactam, and purification of the conducting polymer nanocomposite. Compared with the prior art, the smaller amount of conducting nanofiller are used under the same electric conductivity, thus material costs can be effectively reduced. In addition, the preparation method for reactive extrusion of the conducting polymer nanocomposite is simple in preparation technology and high in preparation efficiency and allows for continuous production. 本发明涉及导电聚合物纳米复合材料的反应挤出制备方法，本发明所述的导电聚合物纳米复合材料由聚酰胺、第二组分聚合物及导电纳米填料组成；本发明所述的导电聚合物纳米复合材料的反应挤出制备方法包括：原料预处理、反应挤出内酰胺阴离子开环聚合、导电聚合物纳米复合材料的纯化。与现有技术相比，在相同导电率下，本发明纳米导电填料的使用量更少，可以有效降
