Analysis structure and morphology of bentonite-opba nanocomposites as nanofillers

Abstract

used as a nanofiller. The methods used to synthesis bentonite nanoparticles are ball mill and co-precipitation and modification with surfactant cetyltrimethylammonium bromide (CTAB). Likewise, the OPBA synthesis process with the ball mill process and co-precipitation. Characterization using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), FTIR and X-ray fluorescence (XRF). The results of characterization using XRD showed a decrease in particle size in bentonite-OPBA nanocomposites. The SEM results show uniformity of particle size in Bentonite-OPBA nanocomposite. Meanwhile, the FTIR results showed absorption peaks indicating bonding in the nanocomposite, confirmed by XRF results. The XRF results show the content of SiO₂ and Al₂O₃ in the nanocomposite so that it can be applied as a nanofiller.
