The persistent issue of oil pollution remains a significant environmental challenge, underscoring the urgent need to develop effective remediation technologies. This comprehensive review explores the role of polymer composites in combating oil pollution, emphasizing their composition, fabrication methods, and performance in various environmental contexts. Polymer composites engineered with high surface areas and tailored hydrophobic and oleophilic properties have emerged as promising solutions for the absorption of oil contaminants from water, soil, and air. The incorporation of natural, synthetic, and hybrid additives into these polymer formulations enhances their functionality and increases their pollutant adsorption capacity. Consequently, these composites demonstrate exceptional efficiency across a wide range of remediation applications. This review consolidates findings from multiple studies, organizing them according to essential criteria such as material composition and performance characteristics. It evaluates recent advancements, particularly in nano-enhanced polymer composites, highlighting their exceptional oil-sorption capabilities compared to traditional sorbent materials. Additionally, the discussion examines the challenges of oil spill remediation, including interactions between contaminants and composite materials. Despite their advantages, significant challenges remain, especially concerning scalability, cost-effectiveness, reusability, and the environmental impact of these materials. The findings underscore the need for further research to address existing knowledge gaps and to facilitate the effective implementation of composite polymers in environmental remediation efforts. Notably, polymer-based nanocomposites can achieve oil sorption capacities of 15-25 g/g, with some advanced formulations exceeding this range under optimized conditions. Furthermore, incorporating nanomaterials, such as graphene and nanoclays, significantly enhances both adsorption efficiency and mechanical durability, enabling oil recovery rates exceeding 90% across multiple reuse cycles. This paper aims to advance the development of sustainable, effective technologies for managing hydrocarbon pollution through innovative synthesis methodologies and interdisciplinary approaches. Ultimately, the successful application of composite polymers represents significant progress in mitigating environmental disasters resulting from oil spills, aligning with the growing demand for eco-friendly cleaning technologies. This review contributes to the dynamic field of oil pollution control by thoroughly evaluating recent advancements and exploring future opportunities related to composite polymer applications and their crucial role in enhancing environmental protection.
