9451871 Snyder This project is improving undergraduate chemical engineering education by introducing the investigation of molecular dynamics for the characterization and analysis of polymers in the polymer and materials science laboratories. This enhancement is being accomplished by developing new experiments using a Tetrahedron Audrey 380A Dielectric Spectrometer System. These experiments provide students with insight into the molecular basis for polymer properties, many of which are strongly linked to chain dynamics and molecular mobility. Without this hands-on experience in polymer structure-property relations, it is extremely difficult for the students to apply classroom concepts to the design, development and fabrication of advanced materials. Using this equipment to perform experiments, the students are able to study important problems such as the fabrication of advanced composites and the recycle of plastics. An outcome of these problem- solving laboratories will be scientists and engineers with considerable experience in materials engineering.

小行星9451871 本项目是提高本科化学工程 通过介绍在聚合物和材料科学实验室中对聚合物进行表征和分析的分子动力学研究来进行教育。这种增强是通过使用四面体奥黛丽380 A介电谱仪系统开发新的实验来实现的。 这些实验为学生提供了深入了解聚合物性质的分子基础，其中许多与链动力学和分子流动性密切相关。如果没有这种聚合物结构-性能关系的实践经验，学生很难将课堂概念应用于先进材料的设计，开发和制造。 使用该设备进行实验，学生能够研究先进复合材料的制造和塑料回收等重要问题。这些解决问题的实验室的成果将是在材料工程方面具有相当经验的科学家和工程师。
