چکیده

Three-dimensional graphene (3DG) sponge has attracted increasing attention because it 10 combines the unique properties of cellular materials and the excellent performance of graphene. 11 The preparation of 3DG sponge depends mainly on the self-assembly of graphene oxide sheets. 12 Here, we demonstrate facile fabrication of 3DG sponge with a large-scale and ordered porous 13 structure, exploiting the liquid crystals of large graphene oxide (LGO) and ultralarge graphene 14 oxide (ULGO) sheets. The resulting materials exhibit a low density, high porosity and elasticity. Our 15 work explores a new strategy for organizing the ordered alignment of controlled large GO sheets 16 and exploring the relationship between the microstructures and mechanical properties of 3DG 17 sponge. 18

Highly Confined Phases of Graphene Oxide Sheets

The graphene oxide (GO) is widely used as a graphene precursor. It has been recently evidenced that this object can form different lyotropic liquid crystals phases observed in highly anisotropic colloids. The confinement of GO sheets, a two-dimensional (2D) crystal is herein aim of study. The binary GO water is studied to describe the liquid crystallinity of concentrated dispersions, characteri...

Study of Stone-wales Defect on Elastic Properties of Single-layer Graphene Sheets by an Atomistic based Finite Element Model

In this paper, an atomistic based finite element model is developed to investigate the influence of topological defects on mechanical properties of graphene. The general in-plane stiffness matrix of the hexagonal network structure of graphene is found. Effective elastic modulus of a carbon ring is determined from the equivalence of molecular potential energy related to stretch and angular defor...

Fabrication of high-quality graphene oxide nanoscrolls and application in supercapacitor

We reported a simple and effective way of fabricating one-dimensional (1D) graphene oxide nanoscrolls (GONS) from graphene oxide (GO) sheets through shock cooling by liquid nitrogen. The corresponding mechanism of rolling was proposed. One possibility is the formation of ice crystals during the shock cooling process in liquid nitrogen to be the driving force. The other might be due to the uneve...

Graphene chiral liquid crystals and macroscopic assembled fibres

Chirality and liquid crystals are both widely expressed in nature and biology. Helical assembly of mesophasic molecules and colloids may produce intriguing chiral liquid crystals. To date, chiral liquid crystals of 2D colloids have not been explored. As a typical 2D colloid, graphene is now receiving unprecedented attention. However, making macroscopic graphene fibres is hindered by the poor di...
