| Popis: | The interfacial issue of nanomaterials-filled epoxy coating has seriously restrained its ongoing progress in actual application. In this paper, we reported a novel design for the robust anti-corrosion and anti-friction performance epoxy coating system based on the self-synthesized 2D Co2(OH)2BDC nanosheets with the native compatible interface compatibility and non-conductivity. The composite epoxy coatings(EP) were intensively characterized by a series of spectral instruments. The influence of the filling content of 2D Co2(OH)2BDC nanosheets to the interface structure of epoxy coating was probed by the microcosmic change. Lastly, the anti-corrosive, mechanical and tribological behaviors of the composite epoxy coatings were extensively investigated. At the optimal filling content of 0.6 wt.%, the low frequency impedance modulus of the 2D Co2(OH)2BDC/EP was increased by about 2 orders of magnitude relative to the neat epoxy coating. Moreover, the friction coefficient of the 2D Co2(OH)2BDC/EP was decreases by 20 % due to the layered structure of nanosheets derived from the weak van der Waals force, while the hardness and Young's modulus were separately increased by 41 % and 83.3 % as a result of the better compatibility and dispersion in epoxy matrix to a certain degree. |
