超疏水纳米材料在减轻石油工业造成的环境污染，特别是在清除石油泄漏方面具有重要的应用前景。在这项工作中，从原油中分离的沥青质进行了改性，作为封端剂在疏水二氧化硅纳米粒子（HSNPs）的合成。研究了HSNPs的化学结构、表面形貌、粒径和表面电荷。测量了HSNP膜表面水滴的接触角，研究了HSNP膜的润湿性能。最后，将HSNPs包覆于超疏水砂和聚氨酯海绵上，并将其应用于阿拉伯稠油溢油的清除。
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.
