In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Scott Phillips of the Pennsylvania State University will create new classes of polymers that depolymerize in response to specific applied signals. The approach is to synthesize polymer backbone structures that can depolymerize under specific chain end initiation conditions and then to characterize the physical organic chemistry aspects of the depolymerization process. Next, various protecting groups will be attached to the polymer chain ends, and initiation of the depolymerization reactions after chemical stimulus will be studied. The education plan involves (i) giving demonstrations and lectures to chemistry and physics classes at high schools in southeastern Pennsylvania, (ii) recruiting students from these schools to participate in summer research programs at the Pennsylvania State University, and (iii) recruiting educators from high schools for a separate summer research and professional development program at Penn State. Other broader impacts of the research involve the potential impacts of these new polymer classes on sensing and diagnostic sciences and the longer term potential uses of polymers that can be chemically reused.Plastics are found in many facets of everyday life, including food packaging, structural materials for automotive and aerospace transportation, and lightweight electronic devices. This work will explore fundamental chemistry related to how plastics decompose into constituent molecules. The results from this project could lead to new design principles to make plastics that can be recycled or reused chemically and to make new materials for sensor or diagnostic applications.

在这个由化学部高分子、超分子和纳米化学计划资助的项目中，宾夕法尼亚州立大学的Scott Phillips将创造出根据特定应用信号进行解聚的新型聚合物。该方法是合成能够在特定的链端引发条件下解聚的聚合物主干结构，然后表征解聚过程的物理有机化学方面。接下来，将各种保护基团连接到聚合物链端，并研究化学刺激后解聚反应的引发。该教育计划涉及(I)在宾夕法尼亚州东南部的高中进行化学和物理课程的示范和讲座，(Ii)招募这些学校的学生参加宾夕法尼亚州立大学的暑期研究项目，以及(Iii)招募高中的教育工作者参加宾夕法尼亚州立大学的单独暑期研究和专业发展项目。这项研究的其他更广泛的影响包括这些新的聚合物类别对传感和诊断科学的潜在影响，以及可以化学重复使用的聚合物的长期潜在用途。塑料存在于日常生活的许多方面，包括食品包装、汽车和航空航天运输的结构材料，以及轻型电子设备。这项工作将探索与塑料如何分解成组成分子有关的基础化学。该项目的结果可能导致新的设计原则，以制造可回收或化学重复使用的塑料，并制造用于传感器或诊断应用的新材料。
