Abstract
Conducting polymers offer many advantages over traditional radar absorbing materials (RAM), such as ferrites and carbon black. Conducting polymers are lightweight, corrosion-resistant, and relatively inexpensive. In addition, conducting polymers exhibit a high degree of tailorability and good matrix adhesion. The morphology of a polymer, and thus the conductivity, is highly dependent on reaction conditions, such as temperature, dopant, and oxidant/monomer ratio. Polyaniline has been synthesized under a variety of reaction conditions, including varying dopant, temperature, and oxidant:monomer ratio. The results of the synthetic experiments will be presented. In addition, the polymer has been incorporated into an acrylic matrix under a variety of conditions. The effect of these processing conditions on the conductivity and permittivity has been investigated, and the results will be discussed.
