The nanocomposites of flower-like nickel phyllosilicate particles incorporated into epoxy resin were fabricated via an in-situ mixing process. The flower-like nickel phyllosilicate particles were firstly synthesized using a mild self-sacrificial templating method, and the morphology and lamellar structure were examined carefully. Several properties of mechanical, thermal and tribological responses of epoxy nanocomposites were performed. It was demonstrated that adequate flower-like nickel phyllosilicate particles dispersed well in the matrix, and the nanocomposites displayed enhanced tensile strength and elastic modulus but decreased elongation at break as expected. In addition, friction coefficient and wear rate were increased first and then decreased along with the particle content, and showed the lowest values at a mass fraction of 5%. Nevertheless, the incorporated flower-like nickel phyllosilicate particles resulted in the continuously increasing thermal stability of epoxy resin (EP) nanocomposites. This study revealed the giant potential of flower-like particles in preparing high-quality EP nanocomposites.

花状页硅酸镍的自牺牲模板合成及其在环氧纳米复合材料中作为高性能增强剂的应用

花状页硅酸镍颗粒掺入环氧树脂的纳米复合材料是通过原位制备的混合过程。首先使用温和的自牺牲模板法合成了花状页硅酸镍颗粒,并仔细检查了其形态和层状结构。对环氧树脂纳米复合材料的机械、热和摩擦学响应进行了多项性能测试。结果表明,足够的花状页硅酸镍颗粒在基体中分散良好,纳米复合材料表现出增强的拉伸强度和弹性模量,但如预期的那样降低了断裂伸长率。此外,摩擦系数和磨损率随着颗粒含量的增加先增大后减小,在质量分数为5%时表现出最低值。尽管如此,掺入的花状页硅酸镍颗粒导致环氧树脂 (EP) 纳米复合材料的热稳定性不断提高。这项研究揭示了花状颗粒在制备高质量 EP 纳米复合材料方面的巨大潜力。
