Superhydrophobic fluorinated polystyrene microspheres
were prepared by distillation precipitation polymerization of 4-fluorostyrene
(FSt), styrene (St), with divinylbenzene (DVB) as crosslinker in acetonitrile
in absence of any stabilizer. Both the fluorine contents and sizes of the
polymeric microspheres were tuned via altering the feed ratio of the
fluorinated monomers for polymerization. The films via casting the suspension
with fluorinated microspheres exhibited a superhydrophobic behavior with
contact angles larger than 150o. The resultant microspheres were
characterized by transmission electron microscopy (TEM), Fourier-transform
infrared spectrometry (FT-IR), X-ray photoelectron spectroscopy (XPS), ion
chromatography, and contact angle system.
