Abstract
⺠Hydrolysis of PAN UF membrane in an alkaline solution. ⺠The hollow fiber membrane is treated at a pH 13 alkaline condition. ⺠Time-dependent solid-state 13C NMR spectra are analyzed. ⺠Two distinct rates in the conversion of the cyano groups. ⺠A rapid conversion on or near the membrane surface and a slow conversion of the bulk.
