Abstract

The growing significance of surface properties in modern materials, particularly in medical technology, drives the need for accurate characterization techniques. Traditional contact angle measurements face challenges when applied to intricate surfaces like dental implants. Here, tensiometry applying the Wilhelmy plate method has been described in the last decade to offer one solution for the evaluation of complex surface geometries by quantifying apparent contact angles based on wetting forces. This study evaluates a simple setup employing the Wilhelmy balance concept for immersion angle determination. Instead of using a force sensor as in tensiometers, the wetting force is determined via changes in mass signal by means of an analytical balance available in standard laboratories. The force is thus recorded inverse to conventional tensiometry. The approach was validated on diverse geometries and extended to intricate structures, including plasma-treated dental implants. Results were compared to conventional contact angle analysis systems underlining the reliability of the method in characterizing non-planar and complex surfaces. Additionally, the method was successfully extended to the evaluation of surface energies on planar and non-planar surfaces using various solvent sets. However, results evidenced that specimen geometry can influence the measurements to such an extent that immersion contact angles can no longer be calculated due to capillary effects. An outlook suggests further exploration with a wider range of test liquids to enhance accuracy in surface energy determination.
Wilhelmy 天平--即使在非平面和复杂几何形状上也能确定浸入角和表面能的简单可靠方法?
现代材料的表面特性越来越重要,尤其是在医疗技术领域,因此需要精确的表征技术。传统的接触角测量方法在应用于牙科植入物等复杂表面时面临挑战。在过去十年中,应用 Wilhelmy 板法的张力测量法为复杂表面几何形状的评估提供了一种基于润湿力量化表观接触角的解决方案。本研究评估了采用威廉天平概念测定浸入角的简单装置。湿润力不是像拉力计那样使用力传感器,而是通过标准实验室中的分析天平的质量信号变化来确定。因此,力的记录与传统的张力计相反。该方法已在各种几何形状上得到验证,并扩展到复杂结构,包括等离子处理的牙科植入物。结果与传统的接触角分析系统进行了比较,强调了该方法在表征非平面和复杂表面方面的可靠性。此外,该方法还成功扩展到使用各种溶剂组评估平面和非平面表面的表面能量。然而,结果表明,试样的几何形状会影响测量结果,以至于由于毛细管效应而无法计算浸入接触角。展望未来,建议进一步探索更广泛的测试液体,以提高表面能测定的准确性。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
