摘要

超疏水材料可以解决水资源中的油污问题。本文采用浸渍法制备了具有宏观-微观-纳米多层次结构的超疏水 PDMS-SiO2。该超疏水 PDMS-SiO2 材料具有良好的物理和化学稳定性,在经过砂纸磨损、胶带剥离、水浸泡、酸碱浸泡和高温烘烤后仍能保持其超疏水性。超疏水 PDMS-SiO2 材料具有很高的油水分离效率,最高油水分离效率可达 99% 以上,不同油类的油水分离效率均超过 96%。超疏水 PDMS-SiO2 材料制备工艺简单、成本低廉、环境友好,可实现快速、大面积制备,具有良好的工程应用前景。

Easy and fast preparation of superhydrophobic multi-level structures with high stability and oil-water separation efficiency

Easy and fast preparation of superhydrophobic multi-level structures with high stability and oil-water separation efficiency

Superhydrophobic materials can solve the problem of oil pollution in water resources. In this paper, superhydrophobic PDMS-SiO2 with macro-micro-nano multi-level structures was prepared by impregnation method. The superhydrophobic PDMS-SiO2 material has good physical and chemical stability, and retains its superhydrophobicity after sandpaper abrasion, tape peeling, water immersion, acid or alkali immersion, and high temperature baking. The superhydrophobic PDMS-SiO2 material has a high oil-water separation efficiency, with the highest oil-water separation efficiency reaching more than 99%, and the oil-water separation efficiency of different oils all exceeding 96%. The preparation of superhydrophobic PDMS-SiO2 material is simple, inexpensive and environmentally friendly, which can achieve fast and large-area preparation, with good engineering application prospects.

期刊介绍: Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
