Abstract

Weathering Effect on Surface Characteristics of Superhydrophobic/ Hydrophobic Nanocomposites Coating

Highlights

  • Hydrophobic surfaces have attracted a lot of attention because of their unique properties such as self-cleaning, antisticking, and anticontamination

  • Electrospinning technique known as most efficient method to produce nanofibers and nanocomposite coating that owns hydrophobicity characteristics that become popular in public to nanotechnology due to the production of nanofibers with diameter in range of (2nm-5μm), this sort of process basically contains syringe pump, high voltage provenance and collector, polymer solution that prepared set in syringe pump and push in stable flow and the needle with metal type and very small diameter is linked to provenance of high voltage in range of (3KV-30KV) [2]

  • Viscosity and surface tension of the surface were calculated to all polymer solutions before and after add of TiO2 nanoparticles, viscosity test shows that specimen with (20%PS) has that higher value and the reason is amount of polystyrene that add to (DMF) N,NDimethylformamide and higher viscosity shows coated surface with high amount of bead while less viscosity gives coated surface with less bead that form on the surface

Summary

Introduction

Hydrophobic surfaces have attracted a lot of attention because of their unique properties such as self-cleaning, antisticking, and anticontamination. Some of the recent reviews describe the rapid progress in the preparation of hydrophobic surfaces and their functional applications and on the theory relating roughness and wettability [1,2]. Electrospinning technique known as most efficient method to produce nanofibers and nanocomposite coating that owns hydrophobicity characteristics that become popular in public to nanotechnology due to the production of nanofibers with diameter in range of (2nm-5μm), this sort of process basically contains syringe pump, high voltage provenance and collector, polymer solution that prepared set in syringe pump and push in stable flow and the needle with metal type and very small diameter is linked to provenance of high voltage in range of (3KV-30KV) [2].
