“…These peaks resulted from allyamine formation. 27,28,32 The FTIR results demonstrate the appearance of amine groups in coated PVC films surface as evidenced by these absorption bands. It is seen that hydrophilic groups were introduced to the PVC surface after the plasma treatment, which contributed to the wettability of the samples.…”

“…27 Allylamine can be used as a monomer for plasma treatment to make the surface hydrophilic. 28 NH 2 as a group in allylamine, which is a polar and hydrophilic functional group, is found in the structure of allylamine. The present work shows that plasma treatment using amine plasma enhances the hydrophilic character of polymeric substrates.…”

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°to 12°by 104.4°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°C to 380°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. C

An anion exchange membrane for use in a direct methanol alkaline fuel cell (DMAFC) was fabricated by the plasma-polymerization method. Plasma polymerization with 4-vinylpyridine and hexafluoropropene followed by quaternization using 1-bromopropane was conducted in order to prepare an anion exchange membrane using a porous film. Plasma polymerized membranes on various porous films were characterized by their water uptake, ion conductivity, methanol permeability and OHtransport number. TGA curves indicated that the membrane had a mass loss when the temperatures rose to 145 °C. The methanol permeability decreased from 0.25×10 -6 to 0.01×10 -6 cm 2 /s and the OH -transport number increased from 0.89 to 0.93 by hot-press treatment because the porosity of the membrane decreased due to the hot-press treatment. This indicated that the hot-press treatment enhanced the selectivity of the mass transport of the membrane, and the hot-press treatment increased the conductivity of the membrane from 33.5 to 39.3 mS/cm because the membrane became thin by the hot-press treatment. The OCV was improved by the hot-press treatment due to the increased mass transport selectivity.
