Effect of Filler Size in a Graphene-anthracene Carbon-carbon Composite

摘要

Characterizing carbon-carbon composite behavior across multiple length scales is essential to comprehending its macro-scale behavior. This work characterizes a graphene-anthracene composite from the nano- to the micron-scale with a variety of analytical techniques to understand its bulk properties. Three variations of the graphene-anthracene composite are prepared by using graphene sheets of varied sizes as a filler in an anthracene matrix. The graphene materials included 300-800 nm reduced graphene oxide, 1-2 μm graphene nano-platelets and 2-5 μm graphene. The carbon-carbon composite so formed is then characterized at different length scales to understand the graphene additives' influence on the composites' observable macroscopic properties as dependent upon the nano- to microstructure - reported here.
