Abstract[English]
Ohm.centimeters (Ohm.cm) or lower. The composition exhibits a volume electrical resistivity between 2.0E+14 Ohm.cm and 1.0E+03 Ohm.cm, and a molded sample of the composition exhibits a percent Absorbed Power measured in Transmission mode of at least 65% at frequencies of from about 75 GHz to about 110 GHz. Molded articles including micron-sized features that provide the article with high absorption and low reflection properties are also described.[French]
Ohm.centimètre (Ohm.cm) ou moins. La composition présente une résistivité électrique volumique située entre 2,0E+14 Ohm.cm et 1,0E+03 Ohm.cm et un échantillon moulé de la composition présente un pourcentage de puissance absorbée, mesuré en mode transmission, d'au moins 65 % à des fréquences d'environ 75 GHz à environ 110 GHz. L'invention concerne également des articles moulés comprenant des caractéristiques micrométriques qui fournissent à l'article des propriétés d'absorption élevée et de faible réflexion.
