Description
Summary:A study of elemental and chemical composition of Nafion® 117 electrolytic surface was conducted using X-ray photoelectron spectroscopy. The major chemical compositions of the membrane surface were mainly fluorine, car­bon, oxygen, sulphur and titanium with mass concentration percentage of 60.22, 24.54, 11.52, 2.40 and 1.32, respectively. The curve fitting for carbon spectrum indicates three C-F namely, F2-C, F-C and F3-C chemical environments; two types of oxygen chemical environments, O3-S and CF-O-­CF2. In addition, one type of fluorine environment; one type of sulphur environment, S-O3 and one type of titanium environment, Ti-O are found on the surface of the membrane.
