Catalytic Synthesis and Growth Mechanism of Multi-branched Carbon Fibers by Cupric Solution Precursors

摘要：

　　Carbon fibers with different morphologies are obtained using different cupric solution precursors (e.g.,cupric sulfate,cupric nitrate,and cupric chloride) at various temperatures.The morphology of carbon fibers depends on the type of catalyst precursor and reaction temperature but not the concentration of the precursor solution.For example,cupric chloride solution is a desirable catalyst precursor for the growth of carbon fibers with multi-branches at 450 ℃.However,a mixture of carbon sheets and linear fibers forms at 300-350 ℃.The splitting mode can be used to explain the formation of carbon fibers with different morphologies at various reaction temperatures.
