Abstract

Graphene, an atomically thin two-dimensional (2D) material, exhibits outstanding electrical properties and thus has been employed in various electronic devices. However, the device performance strongly depends on the structural variations present in the graphitic lattice, such as crystal domains, grain boundaries, lattice imperfections, dopants, etc., which are nanoscopic in nature. Hence, understanding the correlation between the structure and the electrical properties in the nanoscale is essential. Atomic force microscopy (AFM) techniques provide the best way to picture such relationships, which is particularly in demand for future miniaturized devices. This review article highlights the characterization of the electrical properties of graphene-based materials via AFM-based techniques such as conductive AFM, scanning Kelvin probe microscopy, electrostatic force microscopy, and piezoresponse force microscopy that is certainly beneficial for a broad research community not only working on graphene-based materials but also in the fields of other 2D materials and scanning probe microscopy.

Abstract

Graphene oxide has great potential as filtration membranes because its permeability and selectivity can be controlled through its functional groups. Herein, we studied the morphologies of graphene oxide and polyethyleneimine composite membranes. We demonstrated that polyethyleneimine helps to reduce oxygen-containing functional groups in such composite membranes through Raman, X-ray photoelectron, and Fourier-transform infrared spectroscopies. This indicates that thermally annealed graphene oxide and polyethyleneimine composite membranes tend to remove oxygen functional groups. Furthermore, we investigated the change in permeability due to the reduction in oxygen groups. Consequently, we revealed that the loss of hydroxyl and carboxyl groups impart hydrophobicity to the membranes. Our study is useful for the construction of artificial membranes.
