Abstract Hamaker constant, A, is an important parameter for describing the strength of van der Waals interaction of substances and determinable by using different methods. Wetting is a possible and simple method as comparing with others, however, this method determined A value was varied with employed liquid number for one solid material. A wetting-based process for determining the unique critical Hamaker constant, AC, for one solid material was introduced. By taking the probe liquids with known Hamaker constant, AL, to vs. the known wetting parameters, e.g. cos, for one solid material, the AL-cosθ plot was presented then the similarly as the Zisman plot to extrapolate the presented linear fit to the critical wetting condition, cosθ=l, the AC was determinable. A comparison of this unique AC with different probe liquids devoted AS found that the former has expected advantages in ignoring the liquid number variety and united all employed probes resulted latter for representing one solid material. In order to prove the validity, this work used all data were directly cited from literature and the application related different materials.

固体材料临界 Hamaker 常数的新见解

摘要 哈梅克常数A是描述物质范德华相互作用强度的重要参数，可以用不同的方法测定。与其他方法相比，润湿是一种可行且简单的方法，但是，该方法确定的 A 值随所用液体数而变化，对于一种固体材料。介绍了一种基于润湿的过程，用于确定一种固体材料的独特临界 Hamaker 常数 AC。通过将具有已知 Hamaker 常数 AL 的探针液体与已知润湿参数（例如 cos，对于一种固体材料）进行比较，呈现 AL-cosθ 图，然后与 Zisman 图类似地将呈现的线性拟合外推到在临界润湿条件下，cosθ=l，AC 是可确定的。将这种独特的 AC 与专门用于 AS 的不同探针液体进行比较，发现前者在忽略液体数变化方面具有预期的优势，并且将所有使用的探针结合在一起，后者代表一种固体材料。为了证明其有效性，本工作使用的所有数据均直接从文献和应用相关的不同材料中引用。
