Ultrafine aramid nanofibers prepared by high-efficiency wet ball-milling-assisted deprotonation for high-performance nanopaper

Wet ball milling-assisted deprotonation (BMAD) strategy was put forward and carried out to prepare aramid nanofiber (ANF) with high preparation efficiency (20 g L −1 h −1 ), ultrafine fiber diameter (2.09 nm) and narrow distribution (1.0-4.0 nm).
