It is difficult to accurately construct the internal conductive network of the traditional filled conductive polymers. For the first time, the selective laser sintering is applied to fabricate filled conductive polymers. Firstly, porous graphite skeleton is rapidly prepared by selective laser sintering technology, and then the composite of porous graphite matrix and phenolic resin matrix is realized by hot pressing forming process, and a new type of filled conductive polymers is obtained. The influence of the basic characteristic structure parameters of Y-shaped honeycomb porous graphite skeleton on the electrical properties of the new filled conductive polymers is studied. The Z-direction resistivity calculation model of the new filled conductive polymers is presented and verified by the design experiment. The results show that the new process is feasible. By changing the structure parameters of the basic characteristic unit, the number of internal conductive paths and the parallel series mode of the new filled conductive polymers can be changed, and the active regulation of the electrical properties of the new filled conductive polymers is realized. This provides a new method for the preparation of filled conductive polymers.
