Résumé

Carbon nanotubes (CNTs) are good candidates for electronic and optoelectronic devices because of their unique physical properties [1, 2]. CNT coupling or combination with semi-conducting polymer hosts is a promising strategy to demonstrate cheap functional nanocomposites in printed electronics or optoelectronics fields [3, 4]. Meanwhile the difficulty to finely control their dispersion is a strong limitation to their development. In this work, we report on the controlled structuration of blends of CNT with the poly-(3-hexylthiophene) (P3HT) conjugated polymer, to demonstrate organic nanocomposites presenting improved and tunable electrical properties. First, we present a study on the influence of the main parameters controlling the CNT dispersion and orientation on planar devices or in the polymer host matrix using a simple drop-casting procedure under applied electric field. Used planar inter-digited electrode geometries allows both morphological, spectroscopic, and electrical characterizations, as a function of the experimental conditions used (concentration, nature of the solvent, applied electric field characteristics,etc.). Finally, the resulting field-effect transistor geometry enables the charge transport properties characterization for the obtained nanocomposites as a function of CNT loading and dispersion.
