Selecting a proper material is the first key step for determining suitable membrane application. Hence, the comparison of membrane properties is urgently required to be conducted. This work aimed to compare two common materials of polymer flat sheet membranes, i.e poly(vinylidene) fluoride (PVDF) and polysulfone (PSf), from preparation to characterization. Phase inversion method was applied for both materials using different solvent. PVDF was dissolved in N, N, dimethyl acetamide (DMAc) whereas PSf was dissolved in N-methyl pyrrolidone (NMP) with the same composition ratio of polymer and solvent. The properties of membranes were investigated by FTIR, FE-SEM, water contact angle, and Universal pull machine. FE-SEM result indicates that PSf membrane has larger pores than PVDF membrane. Meanwhile, water contact angle analysis describes that PVDF membrane is more hydrophilic than PSf membrane.
