Abstract

Herein, an efficient oil–water separation polyurethane (PU) with hierarchical CoNi-LDH nanowhiskers was fabricated. After CoNi-LDH@PTMS optimization, the PU surfaces are observed to be highly hydrophobic, with water contact angles of 148°. The fabricated PU@CoNi-LDH@PMTS sponge reveals high absorption capacity for various oils, with up to 93 g/g for dichloromethane. In addition, it shows excellent flux and separation efficiency for various oils, retaining over 94.3 % and 98.4 % of its initial performance even after 10 cycles of separation tests, indicating its long-term effectiveness in continuous separation processes. The PU@CoNI-LDH@PMTS sponge offers significant potential in oil–water separation performance.

高效油水分离用CoNi-LDH纳米晶须修饰高疏水聚氨酯的制备

在此基础上，制备了一种高效油水分离聚氨酯（PU）。CoNi-LDH@PTMS优化后，PU表面具有高度疏水性，水接触角为148°。制造的PU@CoNi-LDH@PMTS海绵显示出对各种油的高吸收能力，对二氯甲烷的吸收能力高达93克/克。此外，它对各种油表现出优异的通量和分离效率，即使经过10次循环分离试验，仍保持其初始性能的94.3%和98.4%以上，表明它在连续分离过程中的长期有效性。PU@CoNI-LDH@PMTS海绵在油水分离性能方面具有巨大潜力。
