Latest Patents

One of his latest patents is a method for making a PVA-graphene film. This process involves creating microwave-irradiated nanocomposites that consist of graphene nanoplatelets dispersed in a polymer matrix. The resulting materials exhibit improved structural and electrical properties. The nanocomposites can be produced using a solution casting technique and feature a bilayer structure, which includes a graphene-enriched layer in contact with a polymer-enriched layer. These nanocomposites are particularly useful as shielding materials for electrical devices, effectively reducing electromagnetic interference.

Another significant patent involves organophilic clay-based drilling fluids containing a Gemini surfactant and polyacrylamide. This formulation includes an aqueous phase and various additives, such as organophilic clay, a Gemini surfactant, and polyacrylamide. The organophilic clay is derived from an ion-exchange reaction product of a clay material, while the polyacrylamide consists of reacted units of acrylamide and acrylate monomers. The rheological properties of this drilling fluid, including gel strength and yield stress, are enhanced by the synergistic effects of the additives, which improve shale swelling inhibition capabilities.
