Effect of TiO2 Powder on the Surface Morphology of MicroNanoporous Structured Hydrophobic Fluoropolymer Based Composite Material

Abstract EN

The present work reports a simple and effective way to produce hydrophobic foams with polyvinylidene fluoride (PVDF) and TiO2 by using a phase separation technique.

This method involved the phase separation during the deposition of PVDF from its DMF solution with nonsolvent water in the presence of TiO2.

The surface morphology of hydrophobic surfaces was characterized by Field Emission Scanning Electron Microscope (FESEM).

The maximum water contact angle of 129° was observed.

The results confirm that the surface texture of polymer composite exhibits mixture of microporous and nanoporous structure.

The impact of TiO2 on the wettability property of polymer composite has been studied.

The proposed methodology might find applications in the preparation of hydrophobic surfaces for industrial applications.
