Abstract
AbstractContact angle measurements were used to study the surface acid‐base characteristics of treated and untreated carbon fibers, and of treated and untreated silicon carbide fibers. It has been shown that, when untreated, the surfaces of these two fibers exhibits “amphoteric,” but the base character is dominant. After oxidization in a liquid phase, the surface acid character of the carbon fibers changes little, whereas the base character becomes much stronger. The treatment, with boiling‐concentrated HNO3 for three hours and the sintering treatment in air at 500°C for eight hours, has little effect on the surface acid‐base characteristics of the silicon carbide fibers. © 1993 John Wiley & Sons, Inc.
