Rapid production of silicon-containing vapor grown carbon fibers using the liquid pulse injection technique

Silicon containing vapor grown carbon fibers have been rapidly produced from a mixture of benzene and phenyl silane, using the liquid pulse injection technique. Fibers with lengths up to 20 mm were obtained within 1 min at a carbon yield of 0.23. The inclusion of silicon led to the improvement in the oxidation resistivity of the fibers. Moreover, the obtained fibers possessed tensile strengths and electrical resistivities comparable to those of fibers without silicon inclusion. Electrochemical analysis suggests that the included silicon is highly dispersed within the structure of the fibers. (C) 2000 Elsevier Science Ltd. All rights reserved.
