Abstract
Polypropylene (PP) membranes were prepared by using non solvent induced phase separation (NIPS) method. Membrane surface modification was done by grafting Polyethylene glycol (PEG) using energy from 15 kV corona discharge simultaneously. This research conducted by 2 kind of electrodes (positive and negative electrode). By variation of grafting time : 1, 3, and 5 minutes, permeability membrane with negative electrode higher than positive electrode, it was 987,64 L / m2 h bar and 237,67 L / m2 h bar respectively. The IR Spectra confirmed the presence of PEG in PP membranes and radical ions that bind PEG onto surface PP membrane. Visualization of membrane morphology demonstrated uniform structure for modified PP membrane with the pore size within the range 0.2-0.4 µm.
