Due to their unique features such as electron mobility, high surface area, and mechanical toughness, two-dimensional (2D) materials offer a lot of potential for use in electrical devices. Solutions containing 2D nanomaterials can be used to efficiently print, assemble and embed these materials into functional films, thin films, coatings or composites, providing options for a range of industrial and scientific applications, such as energy storage devices, conductors, sensors, optoelectronics and transistors.
Alfa Chemistry has substantial research and development experience in the field of 2D materials and can provide 2D material customized services. To synthesize solutions for a wide range of 2D materials, we use a variety of methodologies. 2D materials that have been successfully turned into 2D solutions include graphene, black phosphorus (BP), hexagonal boron nitride (h-BN), and transition metal disulfides (TMD).

Liquid phase exfoliation, electrochemical exfoliation, and intercalation employing ions to overcome interlayer van der Waals interactions and increase the layers are all popular methods employed by Alfa Chemistry to prepare 2D solutions.
In general, the liquid phase exfoliation (LPE) process starts with the dispersion of bulk crystals in organic solvents or aqueous solutions, the latter with the help of surfactants or polymers. To form monolayers and many layers of material, the exfoliation process is commonly carried out utilizing cavitation or shear. Exfoliation of large crystals with ultrasonically aided exfoliation is a common LPE technique.

Our liquid phase processing steps for bulk lamellar crystals are: (1) dispersion of the bulk crystals in solvent; (2) exfoliation of the bulk crystals by (acoustic) cavitation or shear; and (3) "sorting" of the material sheet size (e.g., by ultracentrifugation). We also use stabilizers (such as surfactants and polymers) to prevent the flakes from colliding and reaggregating after deposition or coating.
We also prepared 2D solutions by forming salts of layered materials that spontaneously dissolve in polar solvents to produce ionic solutions. The benign dissolution preserves the morphology of the starting material, is resistant to reaggregation, and permits only customized monomolecular layers to be obtained in solutions. Importantly, the charge on the anionic nanosheet solute is reversible, allowing for targeted plating across wide areas and the initiation of fresh self-assembly after drying.
In addition, we utilize functional groups, ligands, surfactants, or charges on the surface of nanomaterials to diminish interparticle attraction and so extend the sub-stable lifetime of the resulting dispersions, such as graphene oxide, in the pathways we use to generate 2D material solutions. These technologies produce a wide range of 2D material-based solutions in a variety of solvents that can be tuned to specific purposes.
