To manufacture the highly functional micro devices by plastic forming, mechanical properties and volume resistivity of polypropylene (pp)/vapor grown carbon nanofiber (VGCF) composite film with orientated VGCF in matrix by drawing and extrusion methods were investigated. All test pieces were prepared from 0°, 45° and 90° as based on drawing direction of composite film. Tensile strength and volume resistivity of drawing direction showed good performances than that from the others. This was due to aligned VGCF by drawing method. On the other hand, the VGCF loading on the tensile property of all composite films contributed to increasing of tensile strength, and the best condition was film reinforced with 20wt% VGCF. Further, the volume resistivity was decreased with increasing of VGCF content, and was less than that of the antistatic film.
