快速有效地清理石油泄漏仍然是一个全球性的挑战。采用简单、廉价的浸包三聚氰胺海绵炭化工艺制备了一种超疏水性、强吸附性、优异磁响应性和耐火性能的改性海绵。采用低成本的石油沥青烯和高岭土纳米颗粒作为浸涂试剂。制备海绵的高吸收能力允许快速和连续去除油污染物。海绵具有良好的耐火性能，可在燃烧条件下使用，燃烧出吸收的油后可直接重复使用。重复使用试验表明，改性海绵经过6次再生和重复使用后仍保持较高的吸收率（>85%）。这些特性使得这种合成海绵成为一种很有前途的辅助材料，可以作为一种磁性集油器和一种耐火的柔性油臂，促进有效的现场燃烧清理溢油。介绍了该海绵在现场燃烧清理溢油中的应用实例。
Fast and effective cleanup of oil spills remains a global challenge. A modified commercial sponge with superhydrophobicity, strong absorption capacity, outstanding magnetic response, and fire resistance were fabricated by a facile and inexpensive route of dip-coated melamine sponge carbonization. The low-cost petroleum asphaltene and kaolin nanoparticles were used as the dip-coating reagent. High absorption capacity of the fabricated sponges allowed rapid and continuous removal of oil contaminants. Taking advantage of the good refractory property, the sponges can be used in burning conditions and directly reused after burning out of the absorbed oil. Reusability tests showed that the modified sponges still maintained high absorption capacity (>85%) after six regeneration and reuse cycles. These characteristics make the fabricated sponge a promising aid to promote effective in situ burning cleanup of oil spills, contributing as a magnetic oil collector and a fire-resistant flexible boom. An example usage scenario of the sponges applied to in situ burning cleanup of oil spills is described.
