| Abstract Scope |
Interconnected nanoplatelets architectures are promising structures to overcome agglomeration and promote mechanical reinforcement, electrical and thermal conductivity in polymer composites. Freeze-drying arises as a cost-effective method to manufacture nanosheet foams with tailored properties according to the application. This study uses freeze-dried GNP/BNNP foams infiltrated with high-temperature epoxy to produce polymer nanocomposites for high-performance applications. Mechanical, electrical, and thermal properties were assessed and compared with neat epoxy. The addition of 4 wt.% of graphene in a network structure has enhanced thermal conductivity of neat epoxy by more than 4 times. The 50:50 GNP/BNNP structure showed the highest thermal conductivity, indicating that a network of interconnected GNP and BNNP is already established at this concentration. The same is observed with electrical conductivity, which is the highest for pure GNP/epoxy and decreases by adding BNNP. This study successfully assessed the capabilities of hybrid freeze-dried foams as polymer reinforcement for thermal and electrical applications. |
