Özet

In this study, surface modifications of poly(vinyl chloride) (PVC) films were performed with the plasma polymerization process. For this purpose, allylamine was used as a hydrophilic polymer for surface modification of PVC films. The wettability of PVC films was investigated using contact angle measurement. The water contact angle values increased from 116.4 degrees to 12 degrees by 104.4 degrees for the coated PVC film. Surface free energies of PVC films were calculated using acid-base approaches and increased with increasing plasma treatment time. According to the Fourier transform infrared spectroscopy results, N-H peaks appeared in the expected wavelength. The thermal degradation behaviors of PVC films were investigated by thermogravimetric analysis. The degradation temperature of PVC films was altered by the plasma treatment from 275 degrees C to 380 degrees C. Surface topography of PVC films was examined by atomic force microscopy (AFM). Distinct changes were observed in the topography of plasma-treated PVC surface using AFM results. The results showed that allylamine plasma treatment can be used to enhance hydrophilicity of PVC surfaces.
