Latent Antioxidants Environmentally Responsible Polymer

项目摘要

Consumer goods made from plastic or rubber must be stabilized against degradation caused by exposure to heat, light and oxygen. Renewal of my NSERC Discovery Grant is sought to help our group create technology that improves the lifespan of these products, while reducing their impact on human health and the environment. The central theme of the research program is latency, the state of existing but not yet being active. Our goal is to develop latent antioxidants that can be chemically-bonded to commodity polymers using simple, cost-effective chemistry. Once these polymers are put in service, this polymer-bound functionality will be activated by environmental UV light, oxygen and/or moisture. This new approach to antioxidant technology will protect the article from degradation without risking losses to the environment by leaching, extraction, or release as volatile organic compounds (VOCs). Canadian manufacturers and consumers alike will benefit from an improved lifespan of polymer products and reduced environmental impact. Furthermore, my five-year research program will support the training of 1 PhD, 3 MSc, and 10 BSc thesis students, providing the Canadian marketplace with HQP that understand the fundamentals of polymer stabilization, and possess the hands-on skills that are needed to change industrial practice.

由塑料或橡胶制成的消费品必须稳定在暴露于热，光和氧气引起的降解中。寻求续签我的NSERC Discovery Grant是为了帮助我们的小组创造技术，以改善这些产品的寿命，同时减少它们对人类健康和环境的影响。研究计划的中心主题是延迟，现有的状态但尚未活跃。我们的目标是开发潜在的抗氧化剂，这些抗氧化剂可以使用简单的，具有成本效益的化学物质化与商品聚合物进行化学结合。一旦将这些聚合物投入使用，这种聚合物结合的功能将被环境紫外线，氧气和/或水分激活。这种新的抗氧化技术方法将保护文章免受降解，而不会冒着浸出，提取或释放作为挥发性有机化合物（VOCS）损失环境的损失。加拿大制造商和消费者都将受益于聚合物产品的寿命改善，并减少了环境影响。此外，我的五年研究计划将支持对1位博士学位，3个MSC和10位BSC论文学生的培训，从而为加拿大市场提供HQP，这些HQP了解聚合物稳定的基础知识，并拥有改变工业实践所需的动手技能。
