What are some mechanical properties of reduced graphene oxide such as tensile strength, young's modulus, and any homogenous/ quasi isotropic properties of the material?
May be this article helps you. http://utw10193.utweb.utexas.edu/Archive/RuoffsPDFs/227.pdf
@Sardar Kashif ur Rehman I could not find anything about the tensile strength or really any mechanical properties regarding RGO in the article. Did I miss it?
Hi Alexander M. Szabo , You are right. Ive so far found the elastic modulus of rGO reported 250+/- 150 GPa. No further clear data. Let me know if anyone knows any publications with rGO physical properties and characterization.
@ Tanvir Qureshi The values are hard to come by. Perhaps this is because there are many ways to prepare reduced graphene oxide with many resulting in different tensile properties.
As Alexander M. Szabo mentioned different synthesis process could lead to various forms of RGO. However, the following publication may be useful for further information about elastic modulus of RGO. Tanvir Qureshi
Highly aligned, ultralarge-size reduced graphene oxide/polyurethane

I recommand you to read this paper: https://www.cell.com/matter/pdfExtended/S2590-2385(19)30022-0
The following two papers you can get some resourceful information about the mechanical properties of graphene. Some paper mentioned as ‘graphene’ instead of writing name as ‘reduced graphene oxide’. Cristina Gomez-Navarro et al. reported the graphene monolayer was synthesized by chemical reduction of graphene oxide. The single sheet of graphene showed the extraordinary stiffness of 0.25 TPa with highly flexibility permit to the band until the elastic region. For details, see the attached paper.
Changgu Lee et al. reported the elastic properties and intrinsic breaking strength of monolayer of graphene by nanoindentation in an AFM. The elastic stiffnesses received for the 1st and 2nd order of 340 Nm-1 and -690 Nm-1 and the breaking strength of 42 Nm-1. Please see the attached paper for details information.
