Hydrophobic sorbents with good hydrophobicity and high porosity have drawn attention for removing oil spills from water. In this study, a highly reusable hybrid polymeric sorbent was successfully fabricated by the reaction of Polydimethylsiloxane (PDMS) and fluorinated alkyl silanes via bulk polymerization without using any activator, initiator, or catalyst. The fabricated polymer sorbent exhibits good hydrophobicity and porous structure; thus, it can be applied as a sorbent for the removal of oils from wastewater. The hybrid sorbents presented high hydrophobicity and excellent sorption capacity for a variety of oils and organic liquids, and the sorption capacity ranges between ~500–1800%. Due to its hydrophobic structure, it can selectively absorb oil from the bottom and the water surface, immediately. Its easy one-pot fabrication procedure, high oil sorption capacity, quick sorption-desorption cycles and great reusability without any capacity loss make it a very promising material for oil spill applications.

使用氟代烷基硅烷交联剂制备高疏水性吸附剂以实现高效的油水分离

具有良好疏水性和高孔隙率的疏水性吸附剂在去除水中溢油方面引起了人们的关注。在本研究中,在不使用任何活化剂、引发剂或催化剂的情况下,通过聚二甲基硅氧烷 (PDMS) 和氟化烷基硅烷通过本体聚合反应成功制备了高度可重复使用的杂化聚合物吸附剂。制备的聚合物吸附剂具有良好的疏水性和多孔结构;因此,它可以作为吸附剂用于去除废水中的油类。混合吸附剂对各种油和有机液体表现出高疏水性和优异的吸附能力,吸附能力范围在~500-1800%之间。由于其疏水结构,它可以立即选择性地从底部和水面吸收油。其简单的一锅制造程序,
