Mathematical Model and Simulation Calculation Method Based on the Exfoliation of Single-Layer Graphene from Dispersed Carbon Nanotubes

Abstract

Graphene is a two-dimensional material with excellent performance and unique structure. Since its successful manufacturing in 2004, it has quickly become a research hotspot in the fields of materials, chemistry, physics, and engineering. This article focuses on the study of exfoliated single-layer graphene based on dispersed carbon nanotubes and understands the related theories of carbon nanotubes and exfoliated single-layer graphene on the basis of literature data. The mathematical model and simulation calculation method are analyzed, and then, the effect of the single-layer graphene peeling based on the dispersed carbon nanotubes is tested, mainly to the experimental verification of the peeling process parameters and the influence of the dispersant on the peeling effect, and then, the peeled graphite quality of the graphene was tested, and the test results showed that the thickness of single-layer pure graphene is 0.6-0.9 nm, and the experimental statistics show that the graphene of single-layer and double-layer occupies 81% of the experimental sample; most of the single-layer graphene exfoliated based on dispersed carbon nanotubes in this paper is single-layer, two-layer graphene, and a relatively small amount of multilayer graphene.
