A novel naturally superoleophilic coconut oil-based foam with inherent hydrophobic properties for oil and grease sorption

Scientific Reports
Absorption methods using polyurethane foams (PUFs) have recently gained popularity in treating oil spills. However, conventional petroleum-based PUFs lack selectivity and are commonly surface-modified using complicated processes that require toxic and ...
