The Effect of Low pressure Oxygen Plasma on Moisture properties of poly vinyl chloride

The surface of materials by changing physical, chemical or biological characteristics can be modified with different techniques such as plasma, corona and coating. These modifications alter some properties of materials such as roughness, hydrophilicity, surface charge, surface energy, biocompatibility and reactivity. In this study, O2 plasma technique was carried out to modify the surface of polyvinyl chloride (PVC). Different treatment parameters such as power of plasma, time of treatment and aging time on wettability were investigated. Contact angles and free surface energy of different liquids were investigated by Young’s equation. The characteristic of treated wood was investigated by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).
