Graphene foam (GrF) has become the most sorted nano-filler in the fabrication of multi-functional polymer composites. There have been numerous work in the synthesis of free standing 3D GrF. 3D GrF fabricated through CVD technique is a widely used nano-filler. CVD involves series of chemical processes, resulting in an expensive 3D GrF. Hence not many researchers have the luxury to indulge in GrF based material development. This presentation highlights a simple 2-step fabrication of 3D GrF using 2D graphene nano-platelets (GNP) via freeze drying technique. As-produced 3D GNP has a reticulated micro porous structure. The work also considers the influence of 3D GNP foam on the thermal and mechanical properties of polymers like polydimethylsiloxane (PDMS) and shape memory polymer (SMP) when used as a nano filler. The presentation mainly highlights the competitive edge of 3D GNP over the 3D GrF fabricated by CVD as a nano filler material.
