Abstract[English]
Disclosed herein is a multilayer part comprising: a first layer, wherein the first layer comprises a first polymer composition comprising a first polymer and from about 0.1 wt. % to about 30 wt. % of a first electrically conductive carbon-based filler; a second layer disposed adjacent a surface of the first layer, wherein the second layer comprises a second polymer composition comprising a second polymer and from about 0.01 wt. % to about 10 wt. % of a second electrically conductive carbon-based filler; wherein the multilayer part exhibits a percent reflected power measured in transmission mode of less than 15% when observed according to a Free Space method at frequencies of from about 75 GHz to 110 GHz, when the multilayer part is oriented such that microwave radiation is incident to the second layer of the multilayer part.[French]
Une partie multicouche est présentement divulguée, laquelle comprend : une première couche, la première couche comprenant une première composition polymère comprenant un premier polymère et environ 0,1 % en poids à environ 30 % en poids d'une première charge à base de carbone électriquement conductrice; une seconde couche située adjacente à une surface de la première couche, la seconde couche comprenant une seconde composition polymère comprenant un second polymère et d'environ 0,01 % en poids à environ 10 % en poids d'une seconde charge à base de carbone électriquement conductrice; la partie multicouche présentant un pourcentage de puissance réfléchie mesuré en mode de transmission inférieur à 15 % lorsqu'il est observé selon un procédé d'espace libre à des fréquences d'environ 75 ghz à 110 ghz, lorsque la partie multicouche est orientée de telle sorte que le rayonnement à micro-ondes est incident sur la seconde couche de la partie multicouche.
