“…It has been noted that the oil sorption values increased and that water-crude oil had a better capacity for sorption in the water sy s tem of diesel fuel. Since there are s tronger adhesion forces between the absorbent and the oil surface as the oil viscosity increases, these results can be explained [24,25]. The modified FPU sponge material shows high selectivity, efficiency, and recyclability for oil/ water separation.…”

The aquatic environment may be seriously harmed when cargo gases, diesel, and their compounds leak or are accidentally spilled onto the water's surface. Oil exploration also leads to water contamination. The remaining oil coats the water's surface, resulting in the formation of a thin emulsion of water and oil. Three novel compounds with long chains of linear alkyl groups were grafted to flexible polyurethane (R-FPU) to clean up oil spills. The sorption testing was thoroughly examined and contrasted with the aid of crude oil, diesel fuel, and water-oil systems. It was found that as compared to ungrafted FPU, the chemical sorption of crude oil and diesel fuel was boosted by modified FPU cubes, while water sorption was reduced by roughly 57%. The sorption competence of the modified FPU was highly correlated with the length of the alkyl chain, with the longer alkyl chain significantly increasing sorption capacity. The results demonstrate that oil may be successfully cleaned using modified FPU cubes.

“…This indicates that the crosslinked alkyl chain length of the compounds plays an important role in the capacity of the grafted RPU and FPU foam for crude oil absorbency. Increasing the number of CH2 groups in the alkyl chain length resulted in better crude oil sorption capacity due to the increasing hydrophobicity properties [37].…”

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.

“…The spectroscopic data of bis-chalcones (1C-6C & 8C) are already reported in the literature. [53][54][55][56][57][58][59] Nevertheless, the spectral data of all the newly synthesized target compounds is given in ESI † le.…”
