Abstract Preparation and characterization of nanodiamond dispersed polyamide-based filament was investigated. The nanocomposite filaments exhibited enhanced thermomechanical properties. Transmission electron microscopy (TEM) images showed the ND particles were uniformly distributed in PA matrix, which resulted in uniform stress distribution and transfer of applied stress from matrix to reinforcement. This structure leads to the enhancement of tensile strength and toughness of nanocomposite filaments. Furthermore, incorporation of ND into the PA matrix resulted in higher thermal stability, by delaying the thermal degradation of the PA matrix. This composite has a potential for high performance application.

聚酰胺-纳米金刚石长丝

摘要 研究了纳米金刚石分散聚酰胺基长丝的制备和表征。纳米复合长丝表现出增强的热机械性能。透射电子显微镜 (TEM) 图像显示 ND 颗粒均匀分布在 PA 基体中，这导致应力分布均匀，并将施加的应力从基体转移到增强材料。这种结构导致纳米复合长丝的拉伸强度和韧性的增强。此外，通过延迟 PA 基质的热降解，将 ND 掺入 PA 基质导致更高的热稳定性。这种复合材料具有高性能应用的潜力。
