The static state contact angle technique has been used in study the properties of the CF₄/CH₄ plasma modified PET surface. The surface free energy, polar component and dispersion component before and after plasma treatment and water impregnation were calculated by Keable method. The hydrophobic property of the modified PET surface was improved and the CF₄/CH₄ plasma exhibited a stronger effect than the CF₄ plasma.
- Polyethylene terephthalate,
- CF₄/CH₄ plasma,
- surface modification,
- hydrophobicity
