Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.
