▎ 摘　　要

Porous organosilica intercalated graphene oxide (p-GA) was synthesized via the two-step polymerization method using 1-(2-aminoethyl)-3- aminopropyltrimethoxysilane as monomer. The average pore diameter of p-GA was calculated to be 4.42 nm with the Barret-Joyner-Halenda (BJH) algorithm. Amino and imino groups on the surface of organosilica pore were served as loading sites for molybdate inhibitors(Al-2(MoO4)(3)). The controlled release of inhibitor ions from the molybdate loading p-GA (p-GAMo) occurred during the hydrophilic transformation process of the organosilica pores. The p-GAMo was embedded in polyvinyl butyral (PVB) coating and applied on mild steel. The results show that p-GAMo/PVB coating has active inhibition performance and exhibits high impermeability.
