| Abstract: | PVDF porous nanofibers with superhydrophobic properties were fabricated by a combined electrospinning and PEO template technique.SEM images showed that the as-prepared PVDF porous nanofibers exhibited micro-and nano-secondary pore microstructure.The contact angle as high as 158°can be found for these porous PVDF nanofibers,indicating that PVDF nanofibers process an excellent superhydrophobic performance.As spill adsorbent,PVDF porous nanofibers shows good oil sorption capacity.In the oil absorption experiment,the sorption capacity of porous PVDF fibers for lubricating oil,diesel oil,vegetable oil and gasoline is up to 24.2,11.8,14.0 and 8.4 g/g,respectively.Meanwhile,porous PVDF fibers also show excellent reusability. |
