Carbon nanotube (CNT) dispersed polyimide films were prepared using an ultrasonic homogenizer and a spin coater. Ion irradiation followed by thermal annealing was performed in order to enhance the conductivity of the films. The samples were irradiated at room temperature with 20 keV nitrogen ions at
## Abstract Three series of composite films based on polyimide and MWNTs were prepared by conversion of pyromellitic dianhydride and 4,4β²βoxydianiline in the presence of the nanotubes, followed by thermal imidization. Carboxyβ and aminoβfunctionalized as well as unmodified nanotubes were used. It w
