The polymer conductive composites with extremely electrical and mechanical properties can be fabricated by adding CNTs into the polymer matrix. The polymer/CNTs composites with a directional structure may be used in many fields such as optic, electric, magnetic and biometric materials. Based on the electrical properties of CNTs, three fabrication methods and the current progress of polymer/CNTs conductive composites are reviewed in detail in the present paper. Special attention is drawn to introducing how to prepare the polymer/CNTs composite with a directional structure. The preparation routines such as template assembly, force-field inducing, and external field alignment are introduced. The principles and the intrinsic characteristics of these routines are analyzed and compared. Finally, the applications and the trends in research of polymer/CNTs conductive composites are preliminarily discussed.
