Investigation of microscopic particle physical properties on inter-particle forces and mechanistic extension to mesoscale manufacturing

先前的工作表明，发展对原位粒子-粒子力的理解是将中尺度体积行为与单粒子微观相互作用联系起来的先决条件。与流变、表面涂层和铣磨等现象相关的批量加工问题在Johnson-Matthey（项目工业赞助商）的业务运营中无处不在，解决方案通常是通过在配方中添加额外的组件或“工艺绷带”来实现的。虽然这样的方法有一些优点，但它对提高对基础微观相互作用的认识几乎没有帮助，导致公式越来越复杂，但理解却越来越少。在这方面，有必要建立一个基本的知识库，了解聚合物如何与颗粒相互作用，并研究这种相互作用对分散、流动行为和涂层性能等整体性能的影响。模型粒子系统可以合成特定的几何形状和大小，这将有助于测量这种粒子-粒子相互作用。然后，这些模型系统可以与Johnson-Matthey相关系统相关联，例如用于排放控制技术（立方）的沸石，以及用于先进玻璃技术（球形）的磨碎玻璃颗粒，从而为改进浆料的配方提供见解。

Previous work has shown that developing an understanding of in situ particle-particle forces is a pre-requisite to relate mesoscale bulk behaviour to single particle microscopic interactions. Bulk processing issues relating to phenomena such as rheology, surface coating and milling are ubiquitous throughout business operations relating to Johnson-Matthey (the project industrial sponsor) and the solutions are often arrived at with the addition of extra components to the formulation or a "process bandage". While such an approach has some merit, it does little to improve the appreciation of the underpinning microscopic interactions, resulting in formulations of increasing complexity with ever diminishing understanding. In this regard there is a need to build a fundamental knowledge base understanding how polymers interact with particulates and study the impact of this interaction on bulk properties such as dispersion, flow behaviour and coating performance. Model particulate systems can be synthesized to specific geometries, shapes and sizes that will facilitate the measurement of such particle-particle interactions. These model systems can then be related to Johnson-Matthey relevant systems such as zeolites for Emission Control Technology (cubic), and milled glass particles for Advanced Glass Technology (spherical), in relation to offering insight for improved formulation within the resulting slurries.
