Novel super-hydrophobic fluorinated silica pellets/poly(aryl ether ketone)composite membranes with controllable structure have been prepared through incorporating poly(aryl ether ketone)s with(3-trifluoromethyl)-phenyl side groups and fluorinated silica pellets(F-SiO2)by a facile one-step electrospinning.Under the condition of adding 50％(mass fraction)F-SiO2 in the composite membrane,the water contact angle(WCA)reached its maximum(157°±4.3°).The controllable micro/nano-structures grown on the electrospun fibers could be regulated by the F-SiO2 loading,which was illustrated by scanning electron microscopy(SEM).Moreover,these super-hydrophobic mem-branes also demonstrated excellent durability,anti-fouling property and oil-water separation ability after 200 h of water flushing.These promising PAEK composite membranes with controllable structure have the potential values in large-scale application of filtration,oil-water separation and antifouling.
