STUDI SOLIDIFIKASI POLIETERSULFON DALAM PELARUT N-METIL-2-PIRROLIDON DENGAN ADITIV POLYVINYL PYRROLIDONE DAN 2-(METHACRYLOYLOXY) ETHYL PHOSPHORYL CHLOLINE

In membrane preparation process via phase inversion method, the morphology of fabricated membranes are determined by composition and concentration of polymer, solvent, and non-solvent. The basic knowledge of the appropriate composition of those component s are needed by cloud point experiment. In this work, the study on cloud point experiment have been done to investigate the solidification process of polymer system of polyethersulfone (PES) and 2-(methacryloyloxy) ethyl phosphoryl chloline (MPC) in N-methyl-2-pirrolidon (NMP) via phase inversion technique. Hydrofilik polymer MPC were used as a membrane modifying agent (MMA) in order to modify the surface property of fabricated membrane. In sum, addition of PVP and MPC into polymer solution brought about reducing amount of non-solvent necessary to obtain the cloud point of solution.
