Graphene has superior electrical, mechanical, and thermal properties over metals making them attractive as electromagnetic shielding for portable and wearable RF electronics in the frequency range 8-18 GHz. These 2D-materials are ultrathin, lightweight, flexible, and optically transparent up to a few layers in thickness, yet graphene has not yet reached its pinnacle potential due to challenges in achieving pristine quality properties. In particular, we compare the shielding effectiveness of single layer to multi-layer CVD grown graphene films and evaluate the development of graphene ink for the same purposes. Furthermore, ink technology will enable the adoption of additive manufacturing techniques for die and IC package shielding with multitude payoffs. We discuss the issues of graphene flake production, functionalization methods, binder selection, adhesion of inks to flexible substrates, and innovations that can lead to new pathways for graphene based materials.
