The composite is a material that is very important in inserting nanoparticles that act as fillers in a matrix. The filler used in this study is Fe3O4 and the matrix used as a polymer is Polypyrrole (PPy). This research aims to analyze the microstructure of Fe3O4 /PPy composite synthesized by sol-gel method. This research was conducted by varying the composition of Fe3O4:PPy including 30%, 40%, 50%, 60%, and 70% w/w. The sample was characterized by Fourier Transform Infrared (FTIR) and Scanning Electron Microscope (SEM). The results of the FTIR characterization, it was found that the Fe3O4 /Polypyrrole has functional groups O-H, CC and C=C. The results of SEM characterization, the particle sizes of each variation composition of Fe3O4:PPy 30%, 40%, 50%, and 70% w/w are 3μm, 3.1μm, 4μm, and 4.5μm, respectively. Based on the results of the study, the greater the composition of the polypyrrole, the greater the particle size. © Published under licence by IOP Publishing Ltd.
