•Optimal nanoparticles are controlling in shape, energy and attraction forces of water droplets on surfaces of polyvinyl chloride nanocomposites.•Nanotech fabrication is a vital process for enhancing industry production of polyvinyl chloride surfaces.
Nanotechnology strategy was used in this work to improve the surface energy properties of polyvinyl chloride (PVC). Different types (clay, ZnO, SiO2 and Al2O3) and concentrations (1wt.%, 5wt.% and 10wt.%) of nanoparticles were investigated. The morphology, dielectric constant, contact angle, wetting energy, spreading coefficient and work of adhesion were investigated for pure PVC and PVC nanocomposites. Tap and salt water were used to study the surface energy properties. The results revealed that the type and concentration of the used nanoparticles affect the properties of the obtained nanocomposites. The change of surface roughness, hydrophilic cites arrangement and dipole/dipole interactions by the change of the type and concentration of the used nanoparticles were the main reason for improving the surface energy properties of PVC nanocomposites.
