Abstract:
To improve the hydrophobic properties of polyurethane foams for oil spill cleanup, the polyurethane foams with nitrile groups are modified by grafting with oleophilic octadecylamine. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and optical contact angle measuring device are used to characterize the modified polyurethane foam. The results show that the octadecylamine can be successfully grafted onto the polyurethane foam and improves the foam hydrophobicity. The modified foam exhibits a higher contact angle (146.3+2.8◦) compared to the unmodified foam (121.4+3.2◦). Moreover, the water sorption of the modified foam is 0.11g/g which is much lower than that of the unmodified foam (0.84g/g). On the other hand, the sorption capacity of the modified foam for toluene, gasoline and diesel sorption is increased by 20-40%. Therefore, the polyurethane foams modified by octadecylamine can be effectively used in oil/solvent spill cleanup.
