摘要
In this work, a humidity-adaptive additive of MoS2@PDA@POSS with core-shell-shell structure was designed and fabricated in the presence of polydopamine (PDA) interlayer. Then the composite coating of MoS2@PDA@POSS/Epoxy was prepared by introducing this additive into epoxy matrix, and its tribological properties under air and humid environments were subsequently evaluated in detail. Specially, the friction coefficient of MoS2@PDA@POSS/Epoxy coating under high humid environment remained stable below 0.25, while its volume wear rate reduced by 91.91% compared to MoS2/Epoxy coating, and the humidity-adaptive response mechanism mainly depends on the improved mechanical properties, the alleviating effect on MoS2 oxidation, and the formation of transfer film. This work establishes a promising platform for the design and application of novel high-performance lubricating additives.
