摘要

一种测量水凝胶电导率的技术(水含量范围38-75%)描述了使用按钮形式的样品,目的是发现电导率与其他可测量变量(如含水量和氧渗透率)之间存在的相关性。该技术通过分析频率范围内的阻抗值来克服电极界面阻抗的问题,并且电导率电池的设计允许研究压缩的影响。到目前为止的结果表明,获得了可重复的电导率值,电导率随着含水量的增加而增加,并且电导率与渗透率之间存在相关性。

A technique for measuring the alternating current electrical conductivity of hydrogels

A technique for measuring the electrical conductivity of hydrogels (range of water contents 38–75%) is described using samples in button form, the aim being to discover the correlations that exist between conductivity and other measurable variables such as water content and oxygen permeability. The technique overcomes the problem of electrode interface impedance by analysing impedance values over a range of frequencies, and the design of the conductivity cell allows effects of compression to be studied. Results so far indicate that reproducible conductivity values are obtained, that the conductivity rises, at an increasing rate, with increase in water content and that there is a correlation between electrical conductivity and permeability.
