Although ocean crude-oil spill accidents did not frequently happened in the past, it really caused great damage to the marine ecosystem once it happened. Because of the spreading and weathering, crude-oil spill usually covers a large area of water surface and its viscosity is very high, which brings human great trouble to clean it up. Dispersant and in-situ burning were frequently used in the past crude-oil spill accidents, but these two methods suffered from the drawbacks including being toxic to marine lives, causing air pollution, disability of recovering the crude oil. Oil skimmers could recovery the oils, but their handling capacities are rather limited. Recently, porous hydrophobic and oleophilic materials (PHOM) have been demonstrated as low-cost, efficient and ecofriendly materials for the oil spill cleanup [1]. Nevertheless, their poor absorption speed to viscous oil spill hinders their practical application.
