Abstract

This paper reports on an essential step towards accelerating the development of new, environmentally friendly active protective coatings by structure optimization. The complex microstructure of the pigment particles within a coating have been observed non-destructively in 3D by nano-computed tomography using synchrotron radiation. For the first time, a stochastic geometry model is fitted based on spatial geometric features of the particles observed in the 3D images. The typical cell of a random Gibbs-Laguerre tessellation is used to model the particles' polyhedral shapes as well as the observed joint size and aspect ratio distributions.

基于 SR 纳米 CT 图像的活性防护涂层中缓蚀剂颜料的几何建模

本文报告了通过结构优化加速开发新型环保活性防护涂层的重要一步。通过使用同步辐射的纳米计算机断层扫描技术，对涂层中颜料颗粒的复杂微观结构进行了三维非破坏性观察。根据三维图像中观察到的颗粒空间几何特征，首次拟合出随机几何模型。随机 Gibbs-Laguerre 网格的典型单元被用来模拟颗粒的多面体形状以及观察到的联合尺寸和长宽比分布。

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
