A novel polydimethylsiloxane-decorated wood carbon sponge (PDMS@WCS) with desirable compressibility and hydrophobicity for fast adsorption and enhanced recovery of crude oil via the promotion of Joule-heating and photothermal effect is reported. The PDMS@WCS can be compressed and released at a constant strain of 50% for multiple times without structural damage, allowing facile exclusion of adsorbed crude oil under external pressure to achieve enhanced recovery.
Fast and efficient cleanup of crude oil spills is still a global challenge because most of the crude oils are highly viscous and lowly fluid. Herein, a kind of polydimethylsiloxane-decorated wood carbon sponges (PDMS@WCS) with desirable compressibility and hydrophobicity for the fast adsorption and enhanced recovery of crude oil via the promotion of Joule-heating and photothermal effect is reported. Moreover, the PDMS@WCS can be compressed and released at a constant strain of 50% for over times without structural damage due to the protection of PDMS coating. Thus, the adsorbed crude oil can be facilely excluded from PDMS@WCS under external pressure to show enhanced recovery.
