<![CDATA[Polyaniline (PANi) was succesfully prepared from Ammonium Peroxodisulfate (APS) and anyline using chemical oxidation method. Silica (SiO2) was synthesized from natural sands taken from Banjar. PANi/SiO2 composites were prepared using mechanical mixing route. The composites were prepared by variating the weight compositions of PANi:SiO2 of 2.5%, and 5% for SiO2. Furthermore, the coating process of Paint-PANi/SiO2 on SS304 stainless stell by spray coating technique. The characterization of anticorrosive behaviour of Paint-PANi/SiO2 was tested by potentiodynamics method. The obtained Tafel curve was then analyzed by means of ANOVA method. The best anticorrosive performance refered to the sample of Paint-PANi/(5%)SiO2, both of before and after exposure processes. The corrotion rate of before and after exposure processes were 0,00896000 mpy and 0,00024408, respectively. DOI: http://dx.doi.org/10.17977/um024v1i12016p025]]>
