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 o indicating the super hydrophilicity than without the PANI presence of 78.8 o . 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/m 2 .h and reasonable molecular weight cut off of below 20,000 g/mol were obtained for the synthesized membrane.Keywords: polyaniline, silicone elastomer, polyvinylidene fluoride, chemical oxidative polymerisation, polymeric acid Abstrak Melaui kajian ini, getah silikon telah digunakan untuk mencapai keinginan menyerap sifat-sifat PANI ke polivinilidin fluorida (PVDF) sokongan mikrobeliang. Poli (vinil metil-eter-alt-asid malik) (PMVEA) asid polimer digunakan sebagai asid pendopan untuk meningkatkan prestasi penapisan membran. Pada mulanya mikro-berliang sokongan PVDF telah disalut dengan larutan elastomer getah silikon diikuti dengan pemendapan PANI oleh teknik pempolimeran kimia oksidatif sel in-situ menggunakan dua bahagian sel dengan kehadiran PMVEA dan ammonium persulfat sebagai agen pengoksidaan. Membran komposit PANI multilapis telah dicirikan secara gravimetrik untuk mengukur kandungan PANI, seperti Mikroskop Imbasan Elektron (SEM), Inframerah Transformasi Fourier (FTIR), kalorimeter pengimbasan pembezaan (DSC) dan sudut sentuhan. Kandungan PANI didapati melebihi 30%. Analsis SEM, FTIR dan DSC telah mengesahkan kehadiran PANI pada membran PANI multilapisan manakala sudut sentuhan membran dengan kehadrian PANI yang tinggi adalah 0 ° menunjukkan keadaan super hidrofilik berbanding tanpa kehadiran PANI adalah 78.8 °. Tekanan penapisan membran komposit PANI multilapis dengan pelbagai julat polietilena glikol pada berat molekul yang berbeza telah diperolehi berdasarkan fluks yang tinggi sehingga 904.11 L/m 2 .h dan berat molekul yang munasabah iaitu di bawah 20.000 g/mol bagi membran yang telah di sintesis.Kata kunci: polianilin, elastomer silikon, polivinilidin fluorida, pempolimeran oksidatif kimia, asid polimer
