We study the influence of melt annealing and the presence of a block copolymer compatibilizer on the electrical properties of polypropylene carbon nanotubes (CNT) nanocomposites from the DC limit to microwave frequencies and link it to the morphological details. We show that the compatibilizer concentration controls three types of morphologies: separate CNT agglomerates, a network of well dispersed but interconnected CNT, and individualized but separate nanotubes. This explains why conductivity reaches an optimum over the whole frequency range at a low compatibilizer concentration. We model the corresponding structures by a semiquantitative schematic equivalent electrical circuit. A key outcome of the work is the understanding and control of dispersion mechanisms in order to optimize the electrical performances for efficient EMI shielding depending on the targeted frequency range.

“…Usually radar absorbing materials are made of thick foam designed for wideband absorption. []Alternatively, thin multilayered coatings can be used but with operation on a narrow frequency band, except when carbon nanotube nanocomposites are considered [2][3][4] .Another approach consists in Frequency-Selective Surfaces (FSS) that enable to achieve nearly perfect absorption, however in a narrow frequency band since planar resonators are used to achieve absorption at resonance [5][6].A further development combines FFS structures with nanocomposite lossy slabs [7].…”

“…In this paper we perform a thorough study of the absorption performances of conductive slabs applicable for example to nanocomposite polymer slabs including carbon nanotubes [2][3][4]. The influence of electrical parameters of the slab, of its-thickness and of the frequency is investigated and explained.…”
