摘要

为了找到一个简单的数学函数来表示绝缘子表面的疏水性水平，对平面聚合物绝缘子表面的水滴模式进行了图像分析。结果，一个简单的函数被命名为“比例熵”，似乎与STRI分类定义的疏水性密切相关。确定了测量过程中的一些各种陷阱，以及避免它们的可能解决方案。

A digital image processing method for estimating the level of hydrophobicity of high voltage polymeric insulating materials

Image analysis of water drop patterns on a flat polymeric insulator surface has been performed in order to find a simple mathematical function that indicates the level of hydrophobicity of an insulator surface. The result, a simple function given the name of "scaled entropy", seems to correlate well with hydrophobicity as defined by the STRI classification. Some of the various pitfalls in the measurement procedure are identified, together with possible solutions for avoiding them.
