Abstract

Sorbent materials for efficient oil–water separation are crucial due to the increasing discharge of industrial and environmental oil pollutants. Herein, we report the fabrication of a superhydrophobic and bacteriostatic poly(triazatruxene) (PTAT)-coated melamine sponge (MF@PTAT) via a one-step in situ polymerization method, utilizing strong π–π stacking interactions between the triazatruxene rings and melamine skeleton. The MF@PTAT material displayed a water contact angle of 158.6°, high porosity, and excellent compression recovery, with an outstanding ability to absorb oils and organic solvents, up to 186.7 g/g. Furthermore, the material demonstrated excellent performance in separating oil–water emulsions, achieving an impressive efficiency of 99.3%. In addition, MF@PTAT demonstrated significant antibacterial performance, effectively inhibiting bacterial growth. The combination of a simple fabrication method, superior oil–water separation efficiency, and strong antibacterial properties makes the low-cost MF@PTAT material highly promising for oil contaminant treatment across various applications.

基于强π -π堆积的超疏水抑菌吲哚基海绵的原位简单制备及高效油水乳液分离

随着工业和环境中石油污染物排放量的增加，高效油水分离的吸附材料变得至关重要。在此，我们报道了利用三氮卓昔环和三聚氰胺骨架之间强π -π堆叠相互作用，通过一步原位聚合方法制备超疏水抑菌聚三氮卓昔（PTAT）包被三聚氰胺海绵（MF@PTAT）。MF@PTAT材料的水接触角为158.6°，孔隙率高，压缩回收率好，吸附油和有机溶剂的能力优异，可达186.7 g/g。此外，该材料在分离油水乳液方面表现出优异的性能，效率达到99.3%。此外，MF@PTAT显示出显著的抗菌性能，有效抑制细菌生长。简单的制造方法、优越的油水分离效率和强大的抗菌性能使这种低成本的MF@PTAT材料在各种应用中对油类污染物的处理非常有前景。
