Abstract: The present invention relates to a polymer composite material comprising an aramid nanofiber (ANF), and a method for preparing same. More specifically, the present invention relates to an arylene ether-based polymer or arylene ether imide-based polymer composite material which is obtained by mixing an arylene ether-based polymer or an arylene ether imide-based polymer with aramid nanofibers dispersed in a polar aprotic solution or by adding and polymerizing monomers in the dispersion of aramid nanofibers.
