高分子材料服役寿命预测方法最新进展

摘要

Polymeric materials would degrade gradually or even lose use value in usage due to various environmental factors, causing waste of resources or even hidden danger. In response to the problem of aging, various aging mechanism and service lifetime prediction methods have been proposed and various aging indicators, such as macro performances or micro structure or components have been used in aging characterization based on detail study on polymeric materials environmental adaptability. Overview of resent advances in polymeric materials service lifetime prediction methods have been given in this paper in view of aging indictor and characterization.%高分子材料在使用过程中，由于受各种环境因素作用，会逐步出现性能下降，甚至丧失使用价值的老化现象，不仅造成资源浪费，更形成安全隐患。为应对老化问题，研究者以各种宏观性能或微观结构、组份的变化来表征老化过程，针对高分子材料的环境适应性开展了大量研究工作，并在此基础上提出了不同的老化机理和服役寿命预测方法。从高分子材料老化过程表征的视角，综述了近年来高分子材料服役寿命预测方法的最新进展。
