The polymer/sodium chloride (NaCl) mate- rials were prepared by casting method. The PES porous materials were extracted with deionized water to study the pore structure, porosity and water absorption of PES. Using the same particle size porogen, the water absorption of the PES pore material increases with the amount of porogen, but when the mass ratio of PES and porogen is more than a certain degree, the water absorption decreased. The water absorption of the PES pore material was not linearly related to the size of the pore structure using three porosens of different particle sizes. The PES pore structure was characterized by optical microscopy and scanning electron microscopy. It was found that the ma- terial was a three-dimensional porous material with inter-pore connectivity.
