Undergraduate Laboratory In Polymer Science And Engineering

我们的目标是建立一个本科实验室在聚合物 理工科本科更新工程 宾夕法尼亚大学的一个项目。拟议 实验室将通过教学使本科生受益 聚合物科学中的重要原理，并介绍它们 最先进的设备项目范围 涉及必修核心课程，选修聚合物课程， 独立的本科研究或设计项目。的 计划的实验室练习包括聚合物合成， 分子和结构计算机模拟 表征、形态学研究和机械性能 财产测量。在合成它们自己的聚合物时， 热力学，动力学和机械性能将是 研究使用差示扫描量热仪和 动态力学分析仪这种热分析设备 将是本科聚合物的主要成分 实验室，由于聚合物特性的多样性 这些仪器可以探测的（例如玻璃化转变， 结晶，模量）。该项目的一个独特之处是 结合分子模拟， 构象和立构规整度，并预测宏观 分子结构的性质。一个热的阶段是必要的 研究聚合物的相变和结晶 使用现有的本科生光学显微镜设备。这 项目的重要性有三个原因：本科 用于研究聚合物科学的实验室设施， 工程目前不存在于宾大，我们的本科生 工程师经常在聚合物或聚合物领域找到工作， 相关领域，最后，聚合物材料具有巨大的 商业和科学的重要性。

We aim to establish an Undergraduate Laboratory in Polymer Science and Engineering to update the undergraduate engineering program at the University of Pennsylvania. The proposed laboratory will benefit undergraduate students by teaching important principles in polymer science and by introducing them to state-of-the-art equipment. The scope of the project involves required core courses, elective polymer courses and independent undergraduate research or design projects. The planned laboratory exercises include polymer syntheses, computer simulations, molecular and structural characterizations, morphology investigations and mechanical property measurements. Upon synthesizing their own polymers, thermodynamic, kinetic and mechanical properties will be investigated using a differential scanning calorimeter and a dynamic mechanical analyzer. This thermal analysis equipment will be a major component of the undergraduate polymer laboratory, because of the variety of polymer characteristics which these instruments can probe (e.g. glass transition, crystallization, moduli). A unique feature of the project is the incorporation of molecular modeling for illustrating chain conformations and tacticity and for predicting macroscopic properties from molecular structures. A hot stage is necessary to study the phase transitions and crystallization of polymers using an existing undergraduate light microscopy facility. This project is significant for three reasons: undergraduate laboratory facilities for the study of polymer science and engineering currently do not exist at Penn, our undergraduate engineers frequently find employment in polymer or polymer- related fields, and finally, polymeric materials are of immense commercial and scientific importance.
