Surface modification of polyacrylonitrile membranes by direct amination has been studied. The membrane was firstly hydrolyzed with NaOH solution, then treated with 1,6hexamethyldiamine(HMDA). Amino amount on the membrane has been measured by titration method. It showed that —NH2 amount varied with hydrolyzation conditions and HMDA concentration. Results of water absorption and contact angle showed that the hydrophilicity of aminated membrane was better than that of original PAN membrane.
