Abstract:
In the present investigation, styrene functionalized polyphenylsulfone (SPPSU) was prepared by reaction of polyphenylsulfone (PPSU) with styrene via Heck reaction. Nanofiltration composite membranes were prepared using crosslinkable styrene-PPSU and the crosslinking reaction performed via UV exposure. Irgacure 2959 and methylenebisacrylamide were added in styrene-PPSU to perform crosslinking reaction. Nanofiltration membranes were tested for Fourier Transform Infrared spectroscopy (FT-IR), Nucleation Magnetic Resonance (NMR), thermal properties, scanning electron microscopy (SEM), and filtration experiments. FT-IR and NMR studies confirmed the substitution of styrene moiety into PPSU main-chains. SEM analysis confirmed the deposition and uniformity of toplayer onto the support. Differential scanning calorimetry (DSC) indicated a decrease in the glass transition temperature of styrene-PPSU. The performance of the membranes changed slightly for acetone and toluene while iso-propanol and n-hexane were completely stable after solvent exposure.
