Under a pressure drop of 0.4 MPa, the water flux of the prepared membrane is 11.1 Lm^(-2)h^(-1), and the retentions of various salts by the prepared membrane are less than 40%, while the retention of polyethylene glycol 1000(PEG 1000) is up to 94.02%.

在0.4MPa下，膜对无机盐的截留率均低于40%，对PEG1000的截留率则达到了94.02%，该膜的纯水通量为11.1Lm^(-2)h^(-1)；能截留低分子量有机物而透过盐，表明该膜可以用于有机物与盐混合溶液的分离。
