Carbon nanotubes (CNTs) filled perfluoroalkoxy (PFA) films with the thicknesses of about 10 mu m have been prepared via blade coating. Both of the CNTs and PFA are aqueous dispersion, which are favorable for the uniform dispersion of fillers into the matrix. The morphology, direct current (DC) resistivity, electrothermal property, and thermal diffusivity of the composite films were studied. We find out that the fraction of CNTs played a vital role in the heating property and thermal transferring capacity of the composite films. Under the input voltage of 110 V, the temperature of PFA composite film with 15 wt % CNT reached to 200(omicron)C, and the thermal diffusivity was about 3.3 mm(2)/s. We believe these CNTs/PFA films are promising alternatives to work as flexible electric heating devices. (C) 2017 Wiley Periodicals, Inc.
