Graphene Oxide (GO) Coating on Reticulated Open-Cell Mullite (ROM) Foams for Enhancing Antibacterial Activity.

ABSTRACT: Graphene oxide (GO) was synthesized by a modified Hummers' method to study its antibacterial activity in two forms: powders and coating agents. Reticulated open-cell mullite (ROM) foams, fabricated by a replica method using polymer foam as the pore template, were enhanced in their antibacterial activity by coating them with the synthesized GO dispersed in aqueous solutions. To fabricate the mullite foams, nano silica (nSiO₂), derived from rice husk (RH), was mixed with commercial alumina (Al₂O₃) and sintered at 1500 °C for 4 h. The sintered foams were pretreated with HCl acid and dip-coated in GO aqueous solutions prepared with a fixed ratio of GO and deionized water. The dip-coating process was performed 3, 5, and 10 cycles to obtain GO multilayers on the
