Beschreibung
Zusammenfassung:	Provided herein are conductive formulations wherein graphene has been added into the metal system, thereby reducing curing shrinkage and improving flexibility, without significantly affecting the EMI shielding performance thereof. In accordance with certain aspects of the present invention, there are also provided methods for filling a gap in an electronic package to achieve electromagnetic interference (EMI) shielding thereof, as well as the resulting articles shielded thereby. In certain aspects of the present invention, there are also provided articles prepared using invention formulations and methods.
