PAN基碳纤维表面液相氧化改性研究
Liquid-Phase Oxidation Modification of PAN-Based Carbon Fiber Surface
摘要
Abstract
The change of the microstructure of carbon fiber with liquid-phase oxidation modification was investigated under different treatment conditions by Raman spectroscopy (daman), Infrared spectroscopy (IR) , and Scanning electron microscope ( SEM). The relationship between microstructure and mechanical properties of monofiber was also studied. The results indicate that surface etching increases surface groove. Acid treatment shows an obvious positive effect on the chemical modification of carbon fiber surface, it increases the grain boundary activity and surface acidic functional groups (-C=O and -OH) , while the graphite microcrystalline decrease. The mechanical properties of the carbon fiber decline after acid treatment. The tensile strength decreases about 15% and 50% respectively, when the times for the liquid-phase treatment are 60min and 120min.关键词
