摘要： The present invention relates to a polymer/filler/metal composite fiber, including a polymer fiber comprising a metal short fiber and a filler; the metal short fiber is distributed as a dispersed phase within the polymer fiber and distributed in parallel to the axis of the polymer fiber; the filler is dispersed within the polymer fiber and distributed between the metal short fibers; the filler does not melt at the processing temperature of the polymer; said metal is a low melting point metal and selected from at least one of single component metals and metal alloys, and has a melting point which ranges from 20 to 480° C., and, at the same time, which is lower than the processing temperature of the polymer; the metal short fiber and the polymer fiber have a volume ratio of from 0.01:100 to 20:100; the filler and the polymer have a weight ratio of from 0.1:100 to 30:100. The composite fiber of the present invention has reduced volume resistivity and decreased probability of broken fibers, and has a smooth surface. The present invention is simple to produce, has a lower cost, and would be easy to industrially produce in mass.
