Pan-based carbon fibers and fabrication method thereof and precursor raw material thereof

摘要

A precursor raw material for the PAN-based carbon fibers represented by Formula (I) is provided.;;In Formula (I), R is methyl, ethyl or propyl, x+z=0.5-20.0 mol %, z≧0.5 mol %, y=99.5-80.0 mol % and x+y+z=100 mol %. The invention also provides a PAN-based oxidized fiber and a PAN-based carbon fiber prepared by the precursor raw material for the PAN-based carbon fibers.
