摘要

颗粒物质流动是一个复杂的多体问题，特别是对于复杂粒子。通过使用固体润滑剂增强了颗粒流动，最近鉴于其在原位破坏力链中的作用，被重新定义为网络破坏剂（NDs）。在此，我们评估了一种 recently reported ND 的属性，以建立可用于增强流动性的标准。我们评估了纤维形状、卷曲度、内腔（s）、机械强度和表面异质性对流变流动能的影响。与扁平纤维相比，圆柱形纤维表现出增强的流动性，而碳化（热解）显著增强了流动性。令人惊讶的是，高抗拉强度和高卷曲指数与流动能的显著降低以及因此流动性增强相关。高抗拉强度与流动性之间的相关性证实了这些材料是力链破坏剂。随着卷曲指数的增加而增强的流动性表明添加剂在颗粒物质基质中的持久性，因此持续破坏力链。
