| Abstract: | A type of hydrophobic/oleophilic functional commercial sponges based on polyurethane(PU)/poly(vinylidene fluoride hexafluoropropylene)(PVDF-HFP)nanofibers composites was successfully prepared through an electrospinning technology at a high relative humidity of 90%and a short collection distance of 6 cm.The morphology and structure of the composite sponge were characterized by SEM,FTIR and XRD,and its oil absorption performance was investigated.The results indicated that the PVDF-HFP nanofibers and PU were partially dissolved and mixed at the interface due to the solvent action of N,N-dimethyl formamide,resulting in a strong binding force.The sponges exhibited excellent hydrophobic properties and a good oil absorption ability with an oil absorption capacity of 30.8 g/g for olive oil,25.2 g/g for lubricating oil,16.8 g/g for dimethyl silicone oil and 26.4 g/g for n-hexane.The sponges also showed an excellent reusability,and their oil absorption could still maintain 97.2%of the original capacity after 50 times cycles. |
