Superhydrophobic nanomaterials are promising in the important pursuit to alleviate the environmental pollution caused by the petroleum crude oil industry, especially to clean-up oil spills. In this work, asphaltenes isolated from crude oil were modified to act as capping agents during the synthesis of hydrophobic silica nanoparticles (HSNPs). The chemical structure, surface morphology, particle size, and surfaces charge of HSNPs were investigated. The contact angles of water droplets on HSNP film surfaces were measured to investigate their wetting properties. Finally, superhydrophobic sand and polyurethane sponge were prepared by coating them with HSNPs and applied in the cleanup of oil spills of viscous heavy Arabian crude oil.
超疏水纳米材料在缓解石油原油工业造成的环境污染这一重要目标中具有广阔前景，尤其是在清理石油泄漏方面。在这项工作中，从原油中分离出的沥青质被改性，以在疏水性二氧化硅纳米颗粒（HSNPs）的合成过程中充当封端剂。对HSNPs的化学结构、表面形态、粒径和表面电荷进行了研究。测量了水滴在HSNP薄膜表面的接触角，以研究其润湿性。最后，通过用HSNPs包覆制备了超疏水砂和聚氨酯海绵，并将其应用于粘性重质阿拉伯原油泄漏的清理。
