This Inter-American Materials Collaboration brings together two research laboratories from the State University of New York at Stony Brook (SUNYSB) in the U.S. and the Autonomous University of San Luis Potosi in Mexico to study several fundamental issues of polymer and clay nanocomposites that can have potential applications of benefits to both countries. These issues include (1) the development of new pathways to prepare thermoplastic polymer-clay nanocomposites with direct commercialization importance, (2) the applications of advanced in-situ characterization methods (X-ray, Raman and rheology) to understand the structure and property relationship during processing, and (3) the modeling of clay morphology in nanocomposites based on in-situ X-ray, Raman and rheological studies. The two teams have complementary expertise and research capabilities. The U.S. scientists (Hsiao and Hsu) have considerable experience in synchrotron X-ray scattering, rheological characterizations and structural modeling of complex nanostructured materials and the Mexican scientist (Medellin) is an expert in polymer nanocomposite technology.An immediate benefit of the project is that the proposed activities will produce tight links between two scientific institutions in the US and in Mexico. The project takes particular advantage in exploring the variations of clay materials between Mexico and the United States. The fundamental approach may overcome several pressing problems encountered in the commercialization of polymer/clay nanocomposites today. Furthermore, based on a better understanding of clay exfoliation, clay morphology and orientation during processing, and unique blends of U.S. and Mexican clays, the potential exists to develop highly attractive new commercial products for tomorrow. The project includes the training and the exchange of students and scientists between the two countries. This award is supported by the Division of Materials Research, the Office of International Science and Engineering, and the Office of Multidisciplinary Activities in the Directorate for Mathematical and Physical Sciences.

这项美洲材料合作汇集了来自纽约州立大学的Stony Brook（Sunysb）的两个研究实验室，以及墨西哥的自主圣路易斯大学的自主大学，研究了几个基本问​​题的聚合物和粘土纳米复合物，这些问题可能已经对两国的潜在利益应用。 这些问题包括（1）开发新的途径，以制备具有直接商业化重要性的热塑性聚合物 - 粘土纳米复合材料，（2）高级原位表征方法的应用（X射线，拉曼和流变学）以了解结构和财产在加工过程中的关系，以及（3）基于原位X射线，拉曼和流变学研究的纳米复合材料中粘土形态的建模。这两个团队具有互补的专业知识和研究能力。美国科学家（HSIAO和HSU）在同步加速器X射线散射，流变学特征和复杂纳米结构材料的结构建模方面具有丰富的经验，墨西哥科学家（Medellin）是聚合物纳米复合材料技术的专家。拟议的活动将在美国和墨西哥的两个科学机构之间建立紧密联系。 该项目在探索墨西哥与美国之间的粘土材料的变化方面具有特殊优势。 今天的聚合物/粘土纳米复合材料的商业化遇到的基本方法可能会克服一些紧迫的问题。此外，基于对粘土去角质，加工过程中的粘土形态和方向的更好理解，以及美国和墨西哥粘土的独特混合物，潜在的潜力是为明天开发非常有吸引力的新商业产品。 该项目包括两国之间的学生和科学家的培训和交流。该奖项得到了材料研究部，国际科学与工程办公室以及数学和物理科学局的多学科活动办公室的支持。
