Quantifying the Effects of Geometric Parameters on the Elastic Properties of Multilayer Graphene Platelet Films.

ABSTRACT: Multilayer graphene platelet films (MGPFs) are widely studied for their exceptional mechanical, electrical, and chemical properties. The elastic properties and deformation mechanisms of MGPFs are highly sensitive to their geometric parameters, including graphene platelet size, graphene area fraction, and layer count. Despite extensive experimental and theoretical efforts, systematically quantifying these effects remains a significant challenge, severely hindering the design of high-performance MGPFs. Here, realistic random 3D periodic representative volume element (RVE) models of MGPFs are constructed to perform simulations, quantify the effects of different geometric parameters on all their five independent elastic properties, and uncover the dominant deformation mechanisms.
