Research on the Superhydrophobic Modification of Polyvinylidene Fluoride Membrane

Abstract:

Article Preview

In order to improve the hydrophobic property of Polyvinylidene fluoride (PVDF) membrane, in this paper nano-silica was modified by silane coupling agent firstly, then the modified nano-silica mixed with fluororesin,crosslinking agent and thickener to prepare the super-hydrophobic surface coating, finally the surface coating was covered on PVDF membrane. The results showed that the contact angle of the modified membrane was 162°and the sliding angle was 4°. The modified membrane was test by SEM and AFM, the surface coating on the PVDF membrane formed micro/nano-meter structure such as lotus leaves surface.
