Polyacrylonitrile/ cellulose acetate (PAN/CA)composite nanofibers membrane was prepared by electrospinning and hydrolyzed by reaction with 0.05 mL/L,0.1 mL/L NaOH solution,respectively. Then got polyacrylonitrile/regeneration cellulose (PAN/RC)composite nanofibers membrane.Experi-mental results showed that the parameters of electrospinning assign are as follows:the spinning liquid flow rate is 0.5 mL/h,the applied voltage is 17 kV,and the reception distance is 18 cm,the obtained PAN/CA composite nanofibers diameter is more uniform,and the shape of the nanofiber is stable.Cellu-lose acetate ester group of PAN/CA composite nanofibers can effective hydrolysis after the alkali treat-ment.The static contact angle of the PAN/RC composite nanofiber membrane decreased from 124.7 de-grees to 10.1 degrees after hydrolysis,the hydrophilic properties have been greatly improved.
