Title: Study on the preparation of polyacrylontrile-based carbon nanofibers by solution blowing
Abstract: Carbon nanofibers were prepared by blowing of polyacrylonitrile(PAN) solution,and following stabilization and carbonization treatment.The effect of spinning parameters,including PAN concentration,airblowing pressure,and solution injecting rate,on the morphology of nanofibers precursor were investigated.After oxidized in 260 ℃ air and carbonized in 900 ℃ He,nanocarbon fibers were manufactured.The morphology and structure of PAN nanofibers,preoxidized nanofibers and carbonized nanofibers were characterized.The result showed that spinning parameters played important role in determining the dominating structure of product morphology,and carbon nanofibers with diameters of 100~340 nm were produced.
