Preparation of superhydrophobic cross-linked syndiotactic 1,2-polybutadiene membranes by electrospinning.

In this study, syndiotactic 1,2-polybutadiene (s-PB)/azobisisobutyronitrile (AIBN) membranes were prepared via electrospinning. The obtained membranes were intensively investigated by contact angle analyzer, differential scanning calorimetry (DSC) and environmental scanning electron microscope (ESEM). With increasing the concentration of spinning solution, the obtained membranes were changed from hydrophobic to surperhydrophobic and the contact angle (CA) as high as 157 degrees at higher s-PB concentration.
