Evaluation of the wettability of prepared anti-wetting nanocoating on different construction surfaces

Abstract Generally, the major problems of moisture damage are caused by wetting, and particularly in construction, which has led to extensive research for production hydrophobic (anti-wetting) coatings. The aim this is prepare an anti-wetting (hydrophobic) nanocomposite coating different construction surfaces (ceramic, brick gypsum). Hydrophobic was synthesized using electrospinning technique. Polymethyl methacrylate polystyrene (PS) solutions were prepared ratios then separately reinforced with ZrO 2 ZnO nanoparticles. Contact angle, surface roughness, free energy weathering effects calculated all specimens after being coated. All previously selected materials showed superhydrophobic properties. best results obtained on ceramic PS/ZrO . water contact angle 153° while roughness 0.491 µm also lowest 5.5 mJ/m Weathering conditions tend decrease values due environmental effect but they still have their SEM test used determine morphology nanoparticle size coated PS nano-ZrO
