Abstract
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.
