Abstract
Electromagnetic interference (EMI) shielding articles and methods of producing and using the same are described. The articles include electrically conductive fillers and silsesquioxane-like (SSQ-like) particles distributed inside a polymeric matrix material. In some cases, adding the SSQ-like particles leads to increased porosity of the articles which improves EMI absorbing performance.
