Abstract: The frequent occurrence of oil spills not only results in the waste of petroleum resources, but also poses a serious threat to the marine ecological environment. Considering the large amount of crude oils with high viscosity, it is urgent to develop a sorbent capable of ef-ficiently reducing the viscosity for the cleanup of oil spills. Inspired by the “lotus effect” and “poikilotherm which utilize the solar en-ergy for thermoregulation”, the low surface energy material polydimethylsiloxane (PDMS) and polypyrrole (PPy) were loaded over the island nonwoven fabric to fabricate a novel crude oil sorbent material. The nonwoven fabric achieved an efficient photothermal con-version. Wherein, the fluorine-free PDMS was used to hydrophobically modify the nonwoven fabric, endowing it with excellent oil-water separation performance, with a separation efficiency of up to 95%. After 10 cycles, the separation efficiency of PPy/PDMS modified nonwoven fabric (PPy/PDMS@NF) was still above 90%, demonstrating superior recyclability. In addition, the PPy/PDMS@NF possessed the self-cleaning capabilities. Under light conditions, the PPy/PDMS@NF was rapidly heated up, reducing the viscosity of crude oil and enabling the effective recovery of oil spills. Under one sun illumination (1.0 kW·m-2), the surface temperature of the PPy/PDMS@NF reached to 60.7 ℃, and its sorption capacity for high-viscosity crude oil reached to 7 gcrude oil·gsorbent-1. Thanks to its environmental friendliness and excellent sorption capacity, this work provides a new option for dealing with the high-viscosity marine oil spills.
