Superhydrophobic and oleophilic polyurethane foams were obtained by spray-coating their surfaces with solutions of thermoplastic polyurethane and hydrophobic silicon oxide nanoparticles. The developed functionalized foams were exploited as reusable oil absorbents from stable water-in-oil emulsions. These foams were able to remove oil efficiently from a wide range of emulsions with oil contents from 10 to 80 v.%, stabilized using Span80. The modified foams could reach oil absorption capacities up to 29 g/g, becoming a suitable candidate for water-in-oil stable emulsions separation.
通过用热塑性聚氨酯和疏水性氧化硅纳米颗粒的溶液对其表面进行喷涂，获得了超疏水和亲油的聚氨酯泡沫。所开发的功能化泡沫被用作从稳定的油包水乳液中可重复使用的吸油剂。这些泡沫能够有效地从各种乳液中去除油，这些乳液的油含量为10%至80%（体积分数），使用Span80进行稳定化处理。改性泡沫的吸油能力可达29 g/g，成为油包水稳定乳液分离的合适候选材料。
