In this research from Jong Hak Kim and colleagues, PVC‐g‐POEM graft copolymer was blended with TTIP to form hybrid membranes via a phase separation process in a water bath. Water permeance increased by hybridizing the polymer with TTIP due to the increased surface pore size and porosity. The water permeance of membranes decreased when heated at 80 °C, owed to the increased selective layer thickness. However, the BSA rejection of the neat polymer membrane increased, while that of the TTIP treated membrane decreased. This was attributed to accelerated dissolution of TTIP at 80 °C, resulting in a large number of surface pores. The antifouling performance was significantly improved by TTIP addition and by heating due to increased hydrophilicity. (DOI: 10.1002/app.45932 )
