Metal—organic framework-derived materials have attracted significant attention in the applications of functional materials. In this work, the rod-like nickel-based metal—organic frameworks were first synthesized and subsequently employed as the hard templates and nickel sources to prepare the whisker-shaped nickel phyllosilicate using a facile hydrothermal technology. Then, the nickel phyllosilicate whiskers were evaluated to enhance the mechanical, thermal, flammable, and tribological properties of epoxy resin. The results show that adequate nickel phyllosilicate whiskers can disperse well in the matrix, improving the tensile strength and elastic modulus by 13.6% and 56.4%, respectively. Although the addition of nickel phyllosilicate whiskers could not obtain any UL-94 ratings, it enhanced the difficulty in burning the resulted epoxy resin nanocomposites and considerably enhanced thermal stabilities. Additionally, it was demonstrated that such nickel phyllosilicate whiskers preferred to improve the wear resistance instead of the antifriction feature. Moreover, the wear rate of epoxy resin nanocomposites was reduced significantly by 80% for pure epoxy resin by adding 1 phr whiskers. The as-prepared nickel phyllosilicate whiskers proved to be promising reinforcements in preparing of high-performance epoxy resin nanocomposites.

镍基金属——有机骨架衍生的晶须状页硅酸镍,可有效提高环氧纳米复合材料的机械、易燃和摩擦学性能

金属-有机骨架衍生材料在功能材料的应用中引起了广泛关注。在这项工作中,首先合成了棒状镍基金属有机骨架,随后将其用作硬模板和镍源,使用简便的水热技术制备了晶须状的页硅酸镍。然后,对页硅酸镍晶须进行了评估,以提高环氧树脂的机械、热、易燃和摩擦学性能。结果表明,适量的页硅酸镍晶须可以很好地分散在基体中,拉伸强度和弹性模量分别提高了13.6%和56.4%。虽然添加页硅酸镍晶须无法获得任何 UL-94 等级,它提高了燃烧所得环氧树脂纳米复合材料的难度,并显着提高了热稳定性。此外,证明这种页硅酸镍晶须更喜欢提高耐磨性而不是减摩特性。此外,添加 1 份晶须后,纯环氧树脂的环氧树脂纳米复合材料的磨损率显着降低了 80%。所制备的页硅酸镍晶须被证明是制备高性能环氧树脂纳米复合材料的有希望的增强材料。添加 1 份晶须后,纯环氧树脂的环氧树脂纳米复合材料的磨损率显着降低了 80%。所制备的页硅酸镍晶须被证明是制备高性能环氧树脂纳米复合材料的有希望的增强材料。添加 1 份晶须后,纯环氧树脂的环氧树脂纳米复合材料的磨损率显着降低了 80%。所制备的页硅酸镍晶须被证明是制备高性能环氧树脂纳米复合材料的有希望的增强材料。
