Abstract
Multilayered carbon fiber arrays (MLCFAs) were synthesized by thermal chemical vapor deposition (CVD) without growth substrate, in which plate-like basic copper nitrate was used as catalyst precursor, acetylene and hydrogen as carbon source and heat treatment gas, respectively. The formation of multilayered structure of the product has a close relation to the special thermal decomposition characterization of basic copper nitrate. The growth schematic of MLCFAs was established to elaborate their growth mechanism.
