Abstract

Abstract. To improve the oleophilic and hydrophobic properties of two different types of polyurethane sponge (flexible, FPU, and rigid, RPU) for oil spill cleanup, acrylamido phenyl chalcone palamitamid, a recently synthesized monomer with long chains of linear alkyl groups, was in situ crosslinked with divinylbenzene. Grafted PU cubes were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The water sorption of ungrafted FPU and RPU decreased from 18.05 and 15.66 to 7.31 and 7.06 for grafted FPU and RPU, respectively. The effect of oil type on the sorption capacity testing was explored and compared using crude oil, diesel fuel, and water-oil systems. It was found that the crude oil and diesel fuel sorption of grafted FPU and RPU cubes was increased compared with ungrafted FPU and RPU cubes, and the maximum values for adsorption were recorded using crude oil. These results can be explained by increasing the adherent forces between the adsorbent and the oil surface with increasing oil viscosity, and consequently, the oil adsorption increases. The high oil absorption capacity is mainly attributed to the high porosity of the sponges. The modified FPU and RPU cubes can be effectively used in oil and water spill cleanup.

合成用于溢油处理的功能化软硬聚氨酯

摘要为了改善两种不同类型的聚氨酯海绵（柔性 FPU 和刚性 RPU）的亲油性和疏水性，以用于溢油清理，丙烯酰胺基苯基查尔酮帕拉米酰胺（一种最近合成的具有长线性烷基链的单体）与二乙烯基苯进行了原位交联。傅立叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）对接枝的聚氨酯立方体进行了表征。未接枝 FPU 和 RPU 的吸水性分别从 18.05 和 15.66 降至接枝 FPU 和 RPU 的 7.31 和 7.06。使用原油、柴油和水-油系统探讨和比较了油类型对吸附容量测试的影响。结果发现，与未接枝的 FPU 和 RPU 立方体相比，接枝的 FPU 和 RPU 立方体对原油和柴油的吸附能力有所提高，原油的吸附能力达到最大值。这些结果可以解释为，随着油粘度的增加，吸附剂与油表面之间的粘附力也随之增加，从而吸附油量也随之增加。高吸油量主要归功于海绵的高孔隙率。改良后的 FPU 和 RPU 立方体可有效地用于溢油和溢水的清理。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
