## 4 Conclusions  
The GE-EP@OIMs solid corrosion inhibitor represents a groundbreaking advancement in corrosion prevention, offering unparalleled performance and addressing critical challenges in the oil-and-gas industry. This study introduces a novel and highly effective solution that combines advanced material science, thermal adaptability, and environmental stewardship to deliver long-term infrastructure protection. The key innovations and advantages of GE-EP@OIMs are as follows:  
1. Unprecedented corrosion mitigation performance: This is because GE-EP@OIMs demonstrates exceptional corrosion resistance, particularly at elevated temperatures (50 \({}^{\circ}\)C), where it forms a robust protective layer that significantly reduces corrosion rates. This is achieved through its unique chemical composition and morphological properties, which synergistically inhibit corrosion reactions and ensure prolonged structural integrity. 2. Revolutionary solid-state formulation: Unlike conventional liquid inhibitors, GE-EP@OIMs's solid-state design eliminates challenges associated with uneven dispersion and high-pressure injection systems. This innovation not only simplifies deployment but also reduces operational costs, making it a practical and economically viable solution for field applications. 3. Superior mechanical and thermal resilience: Despite a slight reduction in tensile strength due to OIM incorporation, GE-EP@OIMs maintains excellent mechanical

Its thermal adaptability ensures consistent performance across varying temperatures, a critical feature for oilfield environments. This is enabled by its molecular design, which ensures stability and effectiveness under thermal stress. * Environmental and economic sustainability: GE-EP@OIMs is designed with environmental sustainability at its core. By optimizing material usage and reducing reapplication frequency, it minimizes environmental impact and aligns with sustainable development principles. This positions GE-EP@OIMs as a cost-effective and eco-friendly alternative to traditional inhibitors. * Novel synthesis and high OIM-loading capacity: The synthesis process, which achieves an OIM-loading capacity of 34.75% (significantly higher than the typical 20%), represents a major breakthrough in material design. This high loading capacity, combined with the temperature-responsive release behavior, ensures targeted and efficient corrosion inhibition in chlorine-rich environments. The innovative design and superior performance of GE-EP@OIMs position it as a transformative solution for the oil-and-gas sector, with potential applications extending to other industries facing similar corrosion challenges. By addressing the limitations of conventional inhibitors and offering a cost-effective, environmentally sustainable, and highly efficient alternative, GE-EP@OIMs sets a new benchmark in corrosion prevention.
