Abstract

Metal corrosion considerably affects the global economy; thus, strategies for the prevention of metal corrosion have gained considerable research and industrial attention. To develop one such strategy, herein, molybdenum disulfide-graphene oxide (MoS$_{2}$-GO) nanohybrids is synthesized by a simple method. The as-synthesized MoS$_{2}$-GO nanohybrids are added to waterborne polyurethane acrylates (WPUA) to prepare anticorrosive MoS$_{2}$-GO/WPUA coatings. Firstly, silane-functionalized molybdenum disulfide (A-MoS$_{2}$) via simple covalent functionalization with 3-aminopropyltriethoxysilane (APTES) is obtained. Secondly, MoS$_{2}$-GO nanohybrids are synthesized by a simple method in N, N-dimethylformamide (DMF). Finally, different amounts of the MoS$_{2}$-GO nanohybrids (0, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%) are added to WPUA to prepare MoS$_{2}$-GO/WPUA coatings. The results show that the MoS$_{2}$-GO nanohybrids are synthesized successfully. The surface of the 0.4% MoS$_{2}$-GO/WPUA coating consisting the 0.4% MoS$_{2}$-GO sample is smooth. The contact angle is 99.67$^{\circ}$ and $\vert Z\vert _{0.01{\rm Hz}}$ is 3.19$\times $10$^{7}\Omega \cdot $cm2 after 28 days of immersion in 3.5% NaCl. The Nyquist plot shows a semicircle and the phase angle diagram has a single peak close to 90$^{\circ}$, indicating high corrosion resistance.
