Description
Summary:We introduce a simple preparation procedure for aramid nanofibers from Twaron fibers by using a downsizing process. Alkaline hydrolysis pretreatment brings ionic charges on the fiber surface, allowing facile disintegration of Twaron into nanofibers by virtue of the electrostatic repulsive force. Since the nanofibers can be dispersed homogeneously in water, the processability and formability of the polymer were improved. The resulting aramid nanofibers, having a high degree of physical performance, a uniform nanosized morphology, and a high surface-to-volume ratio, will expand the range of novel applications of aramid fibers.
