Effect of Piperazine Functionalization of Mesoporous Silica Type SBA-15 on the Loading Efficiency of 2-Mercaptobenzothiazole Corrosion Inhibitor

This work intends to study the effect of functionalization of SBA-15 on the loading and release behaviors of 2-mercaptobenzothiazole (MBT). SBA-15 mesoporous silica was first synthesized and functionalized by a postgrafting method using a piperazine silane coupling agent. Then, SBA-15 was loaded with MBT as a corrosion inhibitor. Various characterizations demonstrated that MBT was successfully encapsulated into the interior nanochannels of...
