3D Printing of Electrically Conductive Hybrid Organic-Inorganic Materials

摘要: We present preparation, characterization, and 3D printing of electrically conductive Acrylonitrile butadiene styrene (ABS) polymer. The electrically conducting ABS was prepared by doping carbon fibers (150μm in length, acquired from Nippon Graphite Corporation), at 200 ̊C by using a thermo-plasto mill, with different weight percentages (wt%) of carbon fibers in ABS polymer matrix. Electrical conductivity of samples with following weight percentages (10, 15, 25, 50 and 60 wt% carbon fibers in ABS polymer matrix) were measured using 4-point probe method [1, 2], with a result that percolation threshold occurs at 25wt%, as shown in Fig 1. SEM analysis (Fig. 2) shows uniform dispersion of carbon fibers in ABS polymer matrix, when compared to previously reported methods [3, 4]. Electrical conductivity of 1.013S/m is observed at 50 wt %. We employed melt extrusion technique in order to fabricate cylindrical …
