AFM，XPS and Raman Study on Low Temperature Ammonia Plasma Treatment of Carbon Fiber

Abstract:

Low temperature ammonia plasma surface treatment on asphalt base carbon fiber is reported with 150°C for 60min, 200°C for 60min and without treatment. The surface topography, chemical composition and structural changes were followed by Atomic force microscope(AFM), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy, of which indicate the treatment could improve the density of carbonyl and amino functional group on the surface of carbon fiber, which can also changed carbon crystalline structure. The density of carbonyl and amino functional group was shown higher for the fibers treated at 150°C than for the fibers treated at 200°C which could be attributed to the temperature and introduced Si element factors.
