大多数学生进入大学时没有接触过任何聚合物科学，这导致对美国塑料回收项目的理解不足，实施缓慢。为了解决化学回收方面的知识鸿沟，我们介绍了一个由两部分组成的实验室实验，该实验在多所高中和公共外联活动中进行，以演示通过氨解来解聚PET，以及将裂解的PET碎片再制造成新的芳纶聚合物。学生的体验通过两项实验后作业进行了评估。
Most students enter college without any exposure to polymer science, which leads to the poor understanding and slow implementation of plastic recycling programs in the United States. To address the knowledge gap in chemical recycling, we introduce a 2-part laboratory experiment that was conducted in multiple high schools and public outreach events to demonstrate the depolymerization of PET via aminolysis and the remanufacturing of cleaved PET fragments into a new aramid polymer. Student experiences were evaluated with two postlab assignments.
