Hypochlorous and Urea Modifications on Carbon Fiber Surface and Effects on Microorganism Immobilization
PAN-based carbon fiber (CF) was modified by hypochlorous and urea in current treatments. The CF surface morphology and natures were characterized by specific facilities, such as scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and the degree of moisture. On the other hand, the biocompatibility nature was indicated by immobilization results of microorganisms on CF. The results show that the surface hydrophilicity and roughness of CF surface would contribute greatly to improve the immobilization ability of microorganisms on CF surface, and the produced oxygen on CF has more effect on microorganism immobilization than nitrogen.
