Procedure

This example illustrates the preparation of a graphite fiber product using a process of the present invention. Approximately 0.2 g of the graphite fibers of Example 4 were added to a stirring solution of 0.025 g 4-chloroaniline, 0.070 g 90% nitric acid and 70 g of water. A solution of 0.014 g NaNO2 in 2 g of water was added and the mixture was stirred for 30 minutes. 4-Chlorobenzenediazonium nitrate was formed in situ, which reacted with the graphite fibers. The fibers were removed from the solution, dried in an oven at 110° C., subjected to Soxhlet extraction overnight with THF, and dried. An ESCA analysis of the product gave a chlorine concentration of 0.4 atomic percent. No chlorine could be detected in the unreacted fibers by ESCA. This establishes that chlorophenyl groups are attached to the graphite fiber product.
