Simultaneously improving the tensile strength and modulus of aramid fiber by enhancing amorphous phase in supercritical carbon dioxide

The aramid fiber made from poly( p -phenyleneterephthalamide) PPTA has high strength and high modulus due to a perfect orientation of rigid macromolecular chains. Many attempts to improve the mechanical performance of the aramid fiber were proposed during the last decade; however, simultaneously imp...
