Description

The oil spillage and pollutants in water bodies are a significant concern in the present time. To address this concern, a porous and superhydrophobic nanocomposite film containing layered natural chromite ores with a polymer was fabricated using a simple solution casting method. The flexible film exhibited a good tensile strength of 1.022 kg mm?2 and self-cleaning properties. It showed an excellent oil adsorption of up to ?268% for castor oil and an adsorption efficiency of ?90% for toxic cationic dyes. The presence of high surface charges on the chromite nanosheets enhanced its adsorbing capability. Furthermore, even after being resynthesized from old used film, the composite film maintained its mechanical strength, hydrophobicity, and adsorbing capabilities. Therefore, we believe that the present work can help in cleaning oil and other pollutants from large water bodies and consequently preserving aquatic life. 2025 The Royal Society of Chemistry.
