巨型软化和微观断裂在幽灵链网络中的普适尺度

摘要

本研究表明,幽灵链聚合物网络断裂的表观复杂度完全解耦为两个普适主曲线:(i) 由绝对拉伸决定的宏观软化,(ii) 由相对拉伸唯一决定的微观断裂。利用此前提出的网络力学模型,已推导出量化捕捉微观损伤非线性增长的解析表达式。将软化幂指数与聚合物溶液尺度结合,可得出简单 Novel 关系:σnb/G(c/c)(1/3)\sigma_{nb} / G \propto (c / c^* )^{(-1/3)},其中 σnb\sigma_{nb} 为 nominal broken strength,GG 为初始剪切模量,cc 为 prepolymer 浓度,cc^* 为其重叠阈值。

I have found mistake in the data processing for Fig 1, and the central claim of this manuscript must be reconsidered. Now I am reorganize the manuscript from scratch and the conclusion will differ
