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.

由于其重量低，强度和刚度相对较高，因此高级复合材料被广泛使用。 传统的复合材料依赖于宏观或微尺度增援的使用来提高其性质和性能。 通过使用纳米尺度的增强和结构，可以单独或与宏观结构结合使用，可以开发具有优越的机械，运输和环境特性的复合材料以及性能特征。 但是，如果要有效地应用这项技术，必须以阶段的形式了解纳米强化背后的基本现象以及扩展问题。 建模分析的重点是粘弹性，分子级别的各向异性和异质性，将支持此研究以及纳米/微/宏观水平上材料特性的缩放。 因此，拟议的研究将研究纳米级结构，环境中的纳米级工艺的三位一体以及纳米级的制造过程。 纳米技术的发展代表了材料设计，制造和设想的方式的根本变化。将通过开发多样化和全球团队的发展来实现上述研究目标，该团队将融合来自行业和学术界的专家，并拥有各种专业领域（聚合物化学，聚合物物理学，界面和表面科学，先进的复合材料以及环境科学）以及与年龄段的年龄段以及与毕业生多年的研究生不同的科学家。 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空前的方式从许多层面和许多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。 需要跨学科的团队来研究纳米技术，还需要教育人们在该领域的进步和不同学科。
