SGER: The Development of Responsive Binders for Particle ClustersAbstractThis exploratory research focuses on chemical additives that can manipulate the net interparticle force within clusters of nanometer and micrometer-scale particles. We will exploit the fundamental physical chemistry that governs the adsorption characteristics and conformation of polymeric binder molecules in order to achieve attractive or repulsive contributions to the overall cluster cohesivity. These binders will respond to external triggers (thermal, optical, or chemical) that will enable the user to tailor the cluster strength. In this manner, we hope to enable an unprecedented degree of control over the processing behavior of particle systems. Three categories of research are proposed:(1) Evaluation of candidate chemistries for responsive binders. (2) Development of strategies for applying these responsive binders to particle assemblies.(3) Measurement and analysis of the effectiveness of these binders in modifying processing characteristics. The results of this research have significant potential to impact broadly many aspects of particle science and technology.

摘要本探索性研究的重点是化学添加剂可以控制纳米和微米级颗粒团簇内的净粒子间力。我们将利用基本的物理化学来控制聚合物粘结剂分子的吸附特性和构象，以实现对整个簇内聚性的吸引或排斥贡献。这些粘合剂将响应外部触发（热、光学或化学），使用户能够定制簇强度。通过这种方式，我们希望能够对粒子系统的处理行为进行前所未有的控制。提出了三类研究方向：(1)评价反应性粘结剂的候选化学物质。(2)开发将这些反应性粘合剂应用于粒子组装的策略。(3)测量和分析这些粘合剂在改变加工特性方面的有效性。这项研究的结果对粒子科学和技术的许多方面具有广泛影响的重大潜力。
