Advanced composite materials are widely utilized because of their low weight and relatively high strength and stiffness. Traditional composites rely on the use of macro or micro-scale reinforcements to increase their properties and performance. Through the use of nano-scale reinforcements and structures, either alone or in conjunction with macro-scale structures, composites with superior mechanical, transport, and environmental properties and performance characteristics can be developed. It is necessary however, to understand the fundamental phenomena behind nano-reinforcement in the form of a phase as well as scaling issues if this technology is to be effectively applied. Modeling analyses that focus on viscoelasticity and molecular-level anisotropy and heterogeneity will support this investigation and the scaling of material properties on a nano/micro/macro level. Therefore, the proposed research will investigate the trinity of nanoscale structures, nanoscale processes in the environment, and manufacturing processes at the nanoscale. The development of nanotechnology represents a fundamental change in the way materials are designed, manufactured, and envisioned. The realization of the above research objectives will be accomplished through the development of a diverse and global team that will incorporate experts from both industry and academia, with diverse areas of expertise (polymer chemistry, polymer physics, interfacial and surface science, advanced composite materials, and environmental science) and age groups varying from scientists with many years of experience down to graduate and undergraduate students. The team will consist of three nodes, in the US, Korea and Switzerland. The diverse nature of this team will allow for a global investigation of this project on many levels and from many angles in an unprecedented fashion. Furthermore, it will provide unique opportunities to students and young researchers in the rapidly developing field of nanotechnology. Interdisciplinary teams are needed to study nanotechnology and are also needed to educate people about the advancements and varying disciplines in this field.

先进复合材料由于其重量轻和相对高的强度和刚度而被广泛使用。 传统的复合材料依赖于使用宏观或微观尺度的增强体来提高其性能和性能。 通过单独或与宏观尺度结构结合使用纳米尺度增强材料和结构，可以开发出具有上级机械、运输和环境特性和性能特征的复合材料。 然而，如果要有效地应用这项技术，有必要了解纳米增强相形式背后的基本现象以及缩放问题。 侧重于粘弹性和分子水平的各向异性和异质性的建模分析将支持这项调查和缩放的纳米/微米/宏观层面上的材料性能。 因此，拟议的研究将调查Trinity位一体的纳米结构，纳米工艺在环境中，在纳米级的制造过程。 纳米技术的发展代表了材料设计、制造和设想方式的根本变化。上述研究目标的实现将通过发展一个多元化的全球团队来实现，该团队将包括来自工业界和学术界的专家，具有不同的专业领域（聚合物化学，聚合物物理，界面和表面科学，先进复合材料和环境科学）和年龄组，从具有多年经验的科学家到研究生和本科生。 该团队将由美国、韩国和瑞士的三个节点组成。该团队的多样性将允许以前所未有的方式在多个层面和多个角度对该项目进行全球调查。此外，它将为快速发展的纳米技术领域的学生和年轻研究人员提供独特的机会。 需要跨学科团队来研究纳米技术，也需要教育人们了解该领域的进步和不同学科。
