The resistance of pervaporation (PV) dehydration membranes to organic solvents is of great importance. Polyphenylsulfone (PPSU) is known to resist most organic media; however, its acetone dehydration performance has not been evaluated yet. In the present study, MXene hydrophilic nanosheets with hydroxyl functional groups were synthesized and then incorporated in the PPSU membrane to prepare the PPSU/MXene PV membrane for the first time. The prepared membranes were used in the dehydration of acetone/water and isopropyl alcohol (IPA)/water. By comparing the attenuated total reflectance Fourier transform infrared spectroscopy spectra of the pure membrane and the nanocomposite membrane, the incorporation of hydroxyl functional groups into PPSU via MXene loading was confirmed. MXene improved the hydrophilicity and tensile properties of the membrane. The separation factor in acetone dehydration dropped with MXene incorporation up to 1 wt% and then increased with further MXene loading; however, it stayed almost unchanged in IPA dehydration with adding 0.5, 1, and 1.5 wt% MXene to the membrane. Incorporating 1 wt% MXene, the pervaporation separation index (PSI) was improved by 5.8 times in acetone dehydration and 9.7 times in IPA dehydration. The PPSU/1 wt% MXene membrane provided a remarkably higher separation factor (261 vs. 136) and PSI (99 vs. 58 kg/m2h) in acetone dehydration than in IPA dehydration; however, total flux was slightly lower in acetone dehydration (0.38 vs. 0.43 kg/m2h). This study implies that PPSU/MXene is a promising membrane material for the PV dehydration of organics. Highlights MXene hydrophilic nanosheets were synthesized. The synthesized MXene was loaded into the polyphenylsulfone membrane. PPSU/MXene membranes were used in pervaporation dehydration. MXene improved the hydrophilicity and tensile properties of the membrane. PPSU/MXene is a promising membrane material for PV dehydration of organics.

Currently, plastic waste, limited water resources, and water contamination are challenges of universal concerns. Recycling plastic waste as a membrane for water/wastewater treatment is of great significance from the perspective of environmental protection and safe drinking water supply. In this study, we used for the first time the puffed polystyrene beads waste (PPSBW) as a basic material for the fabrication of an ultrafiltration membrane and Pluronic F127 (PF127) as a plasticizer and hydrophilizing agent. Different ratios of PF127 were added to the casting solution, and the characteristics of the blank PPSBW and PF127‐modified membranes (PPSBW‐PF127) were evaluated in detail. The addition of PF127 increased the turbidity and viscosity of the casting solution, decreased the contact angle (increased the hydrophilicity), decreased the pure water flux, and increased the rejection of humic acid. The PPSBW membrane with 3 wt.% of PF127 showed the highest antifouling properties, the highest cleaning efficiency, and kept a satisfactory BSA and pure water flux for 4 runs. Overall, PF127 improved the hydrophilicity, organic matter separation, and enhanced the antifouling properties of the PPSBW‐derived membrane.Highlights Renew flow: Repurposing plastic waste as a UF membrane was successfully achieved. The PPSBW‐PF127 membrane was applied for wastewater treatment. Mechanical properties showed reasonable response by adding Pluronic F127. The PPSBW‐PF127 membrane demonstrated a significant rejection and permeability. The PPSBW‐PF127 membrane showed the highest antifouling and cleaning properties.
