Oil spillage has damaged public health noticeably and contributed to significant environmental deterioration. As a result, a significant amount of effort has been spent on investigating and developing the sorbent materials capable of separating oil from water. Thus, the sorbent materials that could be effective particularly in oil spill disposal and resolve such environmental issue remain to be explored. We have proposed luffa cylindrica (LC)-polydimethylsiloxane (PDMS) composite forms to remove the oil and organic components that might be hazardous to aquatic organisms. The scaffolds were fabricated using hand lay-up method with various forms of luffa cylindrica i.e., LC mat, flakes and powder. Various characterizations such as scanning electron microscopy (SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA), effective porosity, surface wettability, mechanical stability, cytotoxicity and sorption behavior with respect to oil, phosphate buffer saline (PBS) and few organic solvents were performed. The results showed that the scaffold in combination with P-L flakes was highly effective in eradicating oil spills and removing harmful components of crude oil. Scaffolds composed of P-L mat, P-L flakes, P-L powder, and PDMS (P) exhibited oil absorption efficacy around 16.09 ± 4.62 %, 24.49 ± 3.55 %, 15.52 ± 2.67 % and 5.52 ± 1.44 %, respectively. We anticipate that the proposed scaffolds have the tremendous potential to provide a solution to this significant environmental remediation issue and to serve as a cost-effective method for removing oil spills and hazardous crude oil components.
溢油对公共健康造成了明显的损害，并导致了环境的显著恶化。因此，人们投入了大量精力来研究和开发能够将油从水中分离出来的吸附材料。因此，仍然需要探索能够有效处理溢油并解决此类环境问题的吸附材料。我们提出了丝瓜络-聚二甲基硅氧烷（PDMS）复合材料，以去除对水生生物可能有害的油和有机成分。支架是使用手糊法制备的，丝瓜络的形式有丝瓜络垫、薄片和粉末。对其进行了各种特性分析，如扫描电子显微镜（SEM）、原子力显微镜（AFM）、热重分析（TGA）、有效孔隙率、表面润湿性、机械稳定性、细胞毒性以及对油、磷酸盐缓冲盐水（PBS）和几种有机溶剂的吸附行为。结果表明，支架与 P-L 薄片结合在一起，在消除溢油和去除原油有害物质方面非常有效。由 P-L 垫、P-L 薄片、P-L 粉末和 PDMS（P）组成的支架的吸油效率分别约为 16.09±4.62%、24.49±3.55%、15.52±2.67%和 5.52±1.44%。我们预计，所提出的支架具有巨大的潜力，可以为解决这一重大环境修复问题提供解决方案，并作为一种经济有效的去除溢油和危险原油成分的方法。
