通过简单的气相沉积，然后聚吡咯聚合，然后用棕榈酸改性，合成了高疏水性和高亲油性的海绵。所制备的海绵在分离和清除水面上的不同溢油领域表现出高吸收能力，并且能够乳化油/水混合物。海绵可以反复压缩而不会塌陷。因此，通过简单的机械挤压海绵就可以很容易地收集吸收的油。所制备的疏水海绵可以在静态和湍流条件下从水中收集油。该方法简单、成本低，可制造高亲油和高疏水性海绵，可成功用于有效的溢油清理和水过滤。
A highly hydrophobic and highly oleophilic sponge was synthesized by simple vapor-phase deposition followed by polymerization of polypyrrole followed by modification with palmitic acid. The prepared sponge shows high absorption capacity in the field of separation and removal of different oil spills from water surface and was able to emulsify oil/water mixtures. The sponge can be compressed repeatedly without collapsing. Therefore, absorbed oils can be readily collected by simple mechanical squeezing of the sponge. The prepared hydrophobic sponge can collect oil from water in both static and turbulent conditions. The proposed method is simple and low cost for the manufacture of highly oleophilic and highly hydrophobic sponges, which can be successfully used for effective oil-spill cleanup and water filtration.
