Correlation between orientation behavior of polyacrylonitrile precursor and structure of nascent fiber
Polyacrylonitrile (PAN) precursors with different orientation behaviors were prepared by changing the coagulation bath conditions such as concentration and temperature. The orientation structure of the PAN precursor was determined by the method of sound velocity. X-ray diffraction and optical micros...
