摘要

蠕变行为对于材料的服役应用至关重要. 蠕变分析测试可以有效反映高分子材料的黏弹性本质，解析高分子材料长时间尺度下的力学松弛行为. 本研究以聚丙烯酸(PAA)和聚环氧乙烷(PEO)构筑氢键复合物，并利用共价交联和金属离子配位作用增强氢键网络，研究温度和湿度这两种最主要的环境参数对其蠕变行为的影响. 分别通过时间-湿度叠加和时间-温度叠加构建蠕变柔量主曲线，进一步结合湿度和温度对时间的叠加，构建了更长时间尺度的主曲线，解析了长时间尺度下的力学松弛行为，指导其实际服役和应用.

Abstract

Creep behavior is critical for the service applications of materials. Creep analysis tests can effectively reflect the viscoelastic properties of polymer materials and evaluate the mechanical relaxation behavior of polymer complexes over long time scales. In this work

polyacrylic acid (PAA) and polyethylene oxide (PEO) were used to construct hydrogen-bonded polymer complexes

and covalent cross-linking and metal ion coordination were used to strengthen the hydrogen bond network. The influence of temperature and humidity

the two main environmental parameters

on the creep behavior of these complexes were investigated. With the increase in temperatu

re or humidity

the creep deformation of the three types of films also increases. The creep compliance master curve was constructed by time-humidity superposition and time-temperature superposition respectively. The temperature shift factor (

) conforms to the Williams-Landel-Ferry (WLF) equation. The humidity shift factor (

) is shown as a piecewise linear dependence of water ratio. The coupling of environmental factors greatly affects the properties of hydrogen-bonded complexes. Further combined with the superposition of humidity and temperature on time

the main curve of a longer time scale is constructed

and the mechanical relaxation behavior under a long time scale is analyzed and expounded

so as to guide its practical service and application.
