The work aims to study the effects of solution concentration as well as non-solvent content on surface morphology and hydrophobicity of PVC films, to obtain PVC films with super-hydrophobic surfaces. With tetrahydrofuran as a good solvent and ethanol as a non-solvent, super-hydrophobic polyvinyl chloride (PVC) coating films were prepared on a glass substrate by spin coating based on the principle of non-solvent induced phase separation. The effects of solution concentration as well as non-solvent content on the performance of PVC films were explored by the hydrophobicity, surface morphology, crystallization and thermal analysis. Scanning electron microscopy (SEM) and contact angle results demonstrated that the addition of a certain content of ethanol made the prepared PVC samples form porous films and nano-scale polymer spheres, and thus increased the hydrophobic property of PVC samples. The XRD results showed that the addition of ethanol did not change the amorphous structure of PVC films. It is found that the concentration of the PVC solutions have no significant effects on the hydrophobic property and surface structure of the prepared PVC films. Moreover, a superhydrophobic surface with a surface water contact angle greater than 150° can be formed when the volume ratio of ethanol to solvent is 30% - 40%.
