Joule and photothermal heating offer promising avenues for enhancing oil recovery, desorption, and reusability by reducing the viscosity of highly viscous oils, thereby facilitating their mobility on sorbent surface. This study developed a heatable reduced graphene oxide nanoribbon (r-GONR)-coated polyvinylidene fluoride (PVDF) oil sorbent to address these viscosity challenges. The application of heating increased oil desorption by approximately 50%, significantly outperforming the conventional PVDF mat. The r-GONR sorbent, leveraging the photothermal effect, demonstrated exceptional reusability, maintaining 40% oil desorption efficiency up to the 10th cycle. Furthermore, its high oil desorption and reusability translated into considerable economic benefits, with a revenue potential of 6.4–29.0 $/m², alongside significant environmental impact reduction. This study introduces a novel, sustainable approach to oil desorption and reuse, underscoring the practical applications of heatable materials in enhancing oil recovery.

焦耳和光热加热通过降低高粘度油的粘度，从而促进其在吸附剂表面上的流动性，为提高石油采收率、解吸和可重复使用性提供了有前景的途径。本研究开发了一种可加热的还原氧化石墨烯纳米带 (r-GONR) 涂层聚偏二氟乙烯 (PVDF) 吸油剂，以解决这些粘度挑战。加热的应用使油解吸增加了约 50%，明显优于传统的 PVDF 垫。 r-GONR 吸附剂利用光热效应，表现出卓越的可重复使用性，在第 10 次循环之前仍保持 40% 的油解吸效率。此外，其高油解吸性和可重复使用性转化为可观的经济效益，收入潜力为 6.4–29.0 $/m ² ，同时显着减少环境影响。这项研究介绍了一种新颖、可持续的石油解吸和再利用方法，强调了可加热材料在提高石油采收率方面的实际应用。
