离子聚合物金属复合材料的弹性模量与材料内部的含水量紧密相连，材料置于不同湿度环境下因含水量的差异会导致弹性模量不同，由于过程效应、实时性等因素影响，采用拉伸法测量材料的弹性模量不够准确。采用悬臂梁共振的方法测量该材料风干(吸水)过程中不同时刻的共振频率，通过公式转换计算得到不同时刻下弹性模量，然后通过测量材料在风干过程中含水量变化规律以及含水量与环境湿度的对应关系，最终得到该材料在不同湿度条件下的弹性模量，该方法简便可行，解决了测量不同湿度条件下离子聚合物金属复合材料弹性模量的难题。
Elastic modulus of ionic polymer-metal composite material is closely related to the water content with-in the material,which is decided by different humidity.The tensile way is not accurate.resonance method to measure the elastic modulus of the ionic polymer-metal composite during the dehydration process in different time through formula variation is effective.By establishing the relationship between the environment humidity and moisture content of the material,the elastic modulus of the material under different humidity conditions is obtained.This method is simple and feasible,and can solve the problem of measuring the elastic modulus of i-onic polymer metal composite materials under different humidity conditions.
