In this award, co-funded by The Polymers Program of the Division of Materials Research and the Mechanics & Structures of Materials Program of the Division for Civil and Mechanical Systems, novel layer-multiplying technology will be used to coextrude polymer sheet or film with hundreds or thousands of alternating layers of two or more materials. Layer thicknesses from the macroscale (tens of microns) to the microscale (several microns) and finally to the nanoscale (tens of nanometers) will be created. Motivated by the need for new processing technologies to develop the engineered microstructures of the future, a microlayer facility was created at CWRU. This facility includes a two-component process that produces sheet or film with alternating layers of polymer A and polymer B. A second system adds a third "tie" layer (polymer C) at the interface between each layer of A and B. A research program to explore the possibilities for new materials systems that can be realized with this versatile process is proposed. The proposed research intends to build on the most promising aspects of prior research and to innovate in new areas of opportunity. The specific aims focus on: (1) expanding the flexibility of the coextrusion process to create new anisotropic structures, (2) incorporating an inorganic component in novel ways to produce materials with designed electronic properties, (3) creating microlayered and nanolayered materials having enhanced barrier properties, and (4) probing the nature of polymer adhesion as related to fundamental aspects of polymer blending and alloying.%%%Ultimately, "microprocessing", as exemplified by microlayer and nanolayer coextrusion, can be the basis for creating "smart skins", film and sheet materials with radiation of specific wavelengths and additionally possess barrier characteristics or unusual electronic properties seems possible. The graduate and undergraduate students who participate in the research will have the opportunity to use a unique coextrusion process to design and realize materials systems that were not possible previously. Through written and oral communications, the results of this versatile technology will be translated to the field-at-large including the industrial sector.

在该奖项中，由材料研究部的聚合物计划以及民用和机械系统部材料的力学和结构计划共同资助，新型的层 - 培养技术将用于伴有两种或多种材料的数百层或数千层交替的层。 将创建从宏观（数十微米）到显微镜（几微米），最后到纳米级（数十个纳米）的层厚度。 由于需要新的加工技术开发未来工程的微观结构，在CWRU创建了Microlayer设施。 该设施包括一个两个组件的过程，该过程与聚合物A和聚合物B的交替层产生纸张或薄膜。第二个系统在A和A之间的每个层之间的界面上添加了第三个“ TIE”层（聚合物C）。研究程序探索了可以通过这种通用过程实现的新材料系统的可能性。 拟议的研究旨在基于先前研究的最有希望的方面，并在新的机会领域进行创新。 The specific aims focus on: (1) expanding the flexibility of the coextrusion process to create new anisotropic structures, (2) incorporating an inorganic component in novel ways to produce materials with designed electronic properties, (3) creating microlayered and nanolayered materials having enhanced barrier properties, and (4) probing the nature of polymer adhesion as related to fundamental aspects of polymer blending and合金%% %%最终，“微处理学”，例如Microhayer和Nanolayer共截止，可以成为创建“智能皮肤”，具有特定波长辐射的胶片和材料的基础，此外还具有障碍特性或异常的电子特性。 参加研究的研究生和本科生将有机会使用独特的共截止过程来设计和实现以前无法实现的材料系统。 通过书面和口头通信，这种多功能技术的结果将转化为包括工业部门在内的一般现场。
