| Abstract Scope |
The bottleneck in the processing of polymer composites with 2D materials is their severe agglomeration. Free standing 3D architecture of 2D materials is a popular nano-filler, as their reticulated networks of branches and nodes offer seamless pathway for photon and electron conduction in the polymer. They are fabricated by CVD technique, which demands high energy. Additionally, pristine foams are fragile and easily disintegrate upon handling. The presentation will highlight the fabrication of rigid 3D foams of 2D materials like graphene nanoplatelets (GNP) and hexagonal boron nitride nanoplatelets (BNNP) via freeze drying (FD). The rigid FD GNP and BNNP foams exhibited 1200 and 230 times higher elastic modulus respectively than pristine graphene foam. The FD foams were reinforced in Polydimethylsiloxane (PDMS) and shape memory polymer (SMP) to augment their thermal properties. The improvement in the thermal properties of the polymer nanocomposites will be discussed in details along with their potential applications. |
