Inspired by the ternary structure of natural nacre, robust ternary artificial nacre is constructed through synergistic toughening of graphene oxide (GO) and molybdenum disulfide (MoS2) nanosheets via a vacuum-assisted filtration self-assembly process. The synergistic toughening effect from high mechanical properties of GO and lubrication of MoS2 nanosheets is successfully demonstrated. Meanwhile, the artificial nacre shows high electrical conductivity. This approach for constructing robust artificial nacre by synergistic effect from GO and MoS2 provides a creative opportunity for designing and fabricating integrated artificial nacre in the near future, and this kind of ternary artificial nacre has great potential applications in aerospace, flexible supercapacitor electrodes, artificial muscle, and tissue engineering.
受天然珍珠层的三元结构启发，通过真空辅助过滤自组装工艺，协同增强氧化石墨烯（GO）和二硫化钼（MoS2）纳米片，构建了坚固的三元人工珍珠层。成功证明了 GO 的高机械性能和 MoS2 纳米片的润滑协同增韧效果。同时，人工珍珠层表现出高导电性。通过 GO 和 MoS2 的协同效应构建坚固的人工珍珠层的方法为设计和制造综合人工珍珠层提供了一个有创意的机会，这种三元人工珍珠层在航天、柔性超级电容器电极、人造肌肉和组织工程等领域具有巨大的潜在应用。
