Abstract

In this study, silicone rubbers were used to achieve the desire absorbing properties of PANI onto polyvinylidene fluoride (PVDF) microporous support. Poly (methyl-vinyl ether-alt-maleic acid) (PMVEA) polymeric acid was used as acid dopant to enhance the membrane filtration performance. Initially PVDF micro-porous support was dip-coated with silicone rubber elastomer solution followed by deposition with PANI by in-situ chemical oxidative polymerisation techniques using two-compartment cell in presence of PMVEA and ammonium persulfate as the oxidizing agent. The PANI multilayer composite membranes were characterized by gravimetric for PANI content measurement namely Scanning Electron Microscope (SEM), Fourier-Transform Infrared (FTIR), Differential Scanning Calorimetry (DSC) and contact angle. The PANI content was found to be more than 30 %. SEM, FTIR and DSC analysis have confirmed the presence of PANI onto the multilayers membrane while the contact angle of the membrane in presence of high loading PANI was 0 ° indicating the super hydrophilicity than without the PANI presence of 78.8 °. The pressure filtration of PANI multilayer composite filtration membrane with a range of polyethylene glycols at different molecular weights was obtained based on the high flux up to 904.11 L/m2.h and reasonable molecular weight cut off of below 20,000 g/mol were obtained for the synthesized membrane.
