The intelligent deformation of organic matter in nacre lamellar structure endows nacre high strength and toughness. However, how to increase energy dissipation by imitating the organic layer deformation of nacre to achieve superior mechanical properties with high strength and toughness is still a challenge. In this study, we employed dynamic small molecular hydrogen bonds to toughen a nacre-like composite. Hence, glycerin(Gly) toughened montmorillonite(MMT) - konjac glucomannan(KGM) nanocomposites were firstly constructed by vacuum-assisted filtration. The hydrogen-bonded small molecule results in the tensile strength of MMT-KGM-Gly remaining at 214.9 MPa and the toughness up to 12.3 MJ m-3, which were superior than those of other MMT/polymer composites. The ordered layered structure and MMT nanosheet endow the nacre-like film high transparency and UV shielding performance, which greatly expands its application prospects in the field of optics, aerospace, and construction.

珍珠质层状结构中有机物的智能变形赋予珍珠质高强度和韧性。然而，如何通过模仿珍珠质的有机层变形来增加能量消耗以实现具有高强度和韧性的优异机械性能仍然是一个挑战。在这项研究中，我们采用了动态的小分子氢键来增韧珍珠质状复合材料。因此，首先通过真空辅助过滤制备了甘油（Gly）增韧蒙脱土（MMT）-魔芋葡甘露聚糖（KGM）纳米复合材料。氢键结合的小分子导致MMT-KGM-Gly的拉伸强度保持在214.9 MPa，韧性高达12.3 MJ m-3，优于其他MMT /聚合物复合材料。
