催化剂层油墨是由固体材料、聚合物和溶剂组成的双相材料体系的实例。单个组分之间的纳米级相互作用可以改变与涂层和制造工艺相关的宏观性质（即粘度、表面张力、聚集和流变学）。对这些宏观性质的控制对于可扩展的卷对卷制造期间的受控电极形成是重要的。基本的相互作用包括聚合物垂直杆粒子、粒子垂直杆溶剂和聚合物垂直杆溶剂相互作用。在这项工作中，我们系统地调查聚合物垂直酒吧颗粒的相互作用，通过研究一系列配方油墨组成的不同溶剂（甲醇，异丙醇，辛醇，和水），不同的聚合物负载，和不同的表面电荷的颗粒。油墨老化也得到解决，并在短时间内（
Catalyst layer inks are examples of biphasic material systems composed of a solid material, a polymer, and a solvent. Nanoscale interactions between the individual constituents can alter macroscopic properties that are relevant for coating and manufacturing processes (i.e. viscosity, surface tension, aggregation, and rheology). Control over these macroscale properties are important for controlled electrode formation during scalable roll-to-roll manufacturing. The underlying interactions include polymer vertical bar particle, particle vertical bar solvent, and polymer vertical bar solvent interactions. In this work we systematically investigate polymer vertical bar particle interactions via studying a range of formulated inks composed of different solvents (methanol, isopropyl alcohol, octanol, and water), varying polymer loadings, and particles with different surface charges. Ink aging is also addressed and over short time periods (
