The characteristic of the resistance of the polymer-carbon microcoils composite

摘要：

Novel polymer-carbon microcoils (CMCs) composite has been fabricated by the intercalation of polymer material into free volume contained in carbon micro coils sheets grown by CVD process. Then the resistance of composite was measured in two-probe method. It was observed that the resistances of the composite have good reversibility as the temperature cyclic changing near the room-temperature; in addition, the intercalation of the organic polymers such as poly (vinyl alcohol) can improve the resistance sensitivity. We propose that the resistance change is dominantly determined by the contact junctions of carbon microcoils in the composite，which gives a reasonable explanation to the reversibility.
