Abstract: ZnO(CH3COO)2/posite fiber membrane with rough surface structure was
synthesized through the electrospinning technology, which changed into ZnO nanofiber membrane
after being sintered at 700℃ for 2h. And then the membrane was modified by FAS solution to reduce
the surface energy. The position and microstructure had been characterized by XRD and
SEM, the hydrophobicity had been discussed, both before and after the surface modification. The
results showed that ZnO was well crystallized after being sintered at 700℃. The average diameter of
ZnO nanofibers changed from 234 nm to 447 nm after being modified, but also with changes in the
contact angles which increased from 123°to 151°. The ZnO nanofiber membrane had transformed from
hydrophobic to super-hydro
