Bentonite-OPBA nanocomposite has been made. The preparation of OPBA and bentonite was carried out by calcination process at a temperature of 700oC for bentonite and 500 °C for OPBA and a ball mill process for 10 hours and coprecipitation method with a solution 6 M HCl. Then nano bentonite was synthesized with surfactant Cetyl Trimethyl Ammonium Bromide (CTAB). The XRD analysis obtained a Bentonite-OPBA particle size of 14.46 nm, with a Tetragonal crystal system and density of 3.01200 g/cm3. XRF analysis obtained SiO2 content of 55.1 % FTIR analysis obtained absorption band detected at 981.33 cm-1 indicates that the increase in silica strengthening has in the polymerization process. © 2022 Published under licence by IOP Publishing Ltd.
