高分子材料的老化表征方法

Techniques of characterization aging polymer materials

高分子材料的老化会使其性能降低,从而部分或完全丧失其使用价值,因此对高分子材料的老化与防老化研究已成为高分子科学的重要研究领域。本文从高分子材料老化过程中外观变化、力学性能变化、电性能变化、波普性能变化4个方面综述了高分子材料的老化表征方法,展望了表征高分子材料老化的研究方向。

The aging of the polymer materials makes its performances lower,part or complete lose its using value,the research of aging and defend aging of polymer materials has become more importance in polymer materials science research realm.This paper summarizes the technique of characterization aging polymer materials from four aspects,including： the variety of appearance,mechanics function,electricity function,wave bop function.Prospect the direction of technique of characterization aging polymer materials.
