Characterization and industrial application of a gyroid-shaped novel graphite and MoS2-modified polyamide 3D membrane

Year: 2026

Type: article

Abstract: Industrial growth is generating alarming amounts of oily wastewater. Because these contaminants don’t degrade readily, they threaten ecosystems and human health. Consequently, identifying efficient and cost-effective materials for separating oil from water, particularly for stable emulsions, is a critical environmental challenge that must be addressed. Organic–inorganic hybrid materials are considered among the most promising options for developing membranes. In this study, a novel gyroid-shaped 3D polyamide-graphite-MoS 2 membrane (PGM@gyroid-3D membrane) was fabricated via selective laser sintering. The composition, structure, morphology, and thermal stability of the fabricated PGM@gyroid-3D membrane were characterized using multiple techniques to elucidate its properties. It was observed that graphene and MoS 2 are uniformly spread on the polyamide surface. The surface exhibits low roughness and crystalline topography. The FTIR results confirm the successful creation of the PGM@gyroid-3D membrane. Tensile, compressive, and flexural tests were performed to evaluate and compare the effects of laser power on specimens fabricated from composite powder and pure PA-12. The separation efficiency of the PGM@gyroid-3D membrane for the tested oils was admirable, suggesting that this membrane is a good candidate for industrial oil-contaminated water treatment.
