受天然珍珠层三元结构的启发，通过真空辅助过滤自组装过程，通过氧化石墨烯（GO）和二硫化钼（MoS2）纳米片的协同增韧构建坚固的三元人工珍珠层。成功地证明了GO的高机械性能和MoS2纳米片的润滑的协同增韧效应。同时，人造珍珠层显示出高导电性。这种通过GO和MoS2的协同效应构建坚固的人工珍珠层的方法为在不久的将来设计和制造集成人工珍珠层提供了创造性的机会，这种三元人工珍珠层在航空航天、柔性超级电容器电极、人工肌肉和组织工程中具有巨大的潜在应用。
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.
