在现代世界中，石油基合成聚合物在从食品包装到太空旅行等领域有着大量的应用。然而，石油产品的加工和由此导致的化石燃料的耗尽是当今社会的主要环境问题。因此，由可再生资源和废弃物组成的可持续聚合物的开发是一个正在研究的领域。考虑到世界粮食生产，柑橘类水果是最丰富的，其对废物产生的贡献是巨大的。因此，这项研究的重点是提供一种替代石油基聚合物的方法，并通过开发新型的laccol和柠檬烯共聚物来提供一种管理柑橘废物的监管途径。两种环境友好的化合物，laccol，来自Toxicodendron succedaneumtree的树液和柠檬烯，从橙子皮中提取，通过阳离子聚合共聚生成-柠檬烯：laccol共聚物，具有辐射硬化能力，其在核能发电、药物灭菌、商业辐照和空间探索等领域相关。用红外和核磁共振分析证实了这些共聚物的形成。合成的共聚物使用不同的方法进行表征，并暴露于Co-60 γ辐射以确定其性质的改变。Polym.工程索引，60：607-618，2020.© 2019塑料工程师学会
In the modern world, petroleum‐based synthetic polymers have a great number of applications in fields ranging from food packaging to space travel. However, the processing of petroleum products and the resulting depletion of fossil fuels are major environmental concerns in today's society. As a result, the development of sustainable polymers which are made up of renewable resources and waste products is an immerging area of research. Considering the world food production, citrus fruit is most abundant and its contribution to waste generation is immense. Therefore, this study focuses on offering an alternative to the use of petroleum‐based polymers and also providing a regulatory pathway to manage citrus waste by developing novel copolymers of laccol and limonene. Two environmentally friendly compounds, laccol, derived from the sap ofToxicodendron succedaneumtree and limonene, extracted from orange peels, were copolymerized via cationic polymerization to generated‐limonene:laccol copolymers with radiation hardening capabilities which is relevant in fields such as nuclear energy generation, medicinal sterilization, commercial irradiation, and space exploration. Formation of these copolymers was verified with infrared and nuclear magnetic resonance analysis. The synthesized copolymers were characterized using different methods and exposed to Co‐60 gamma radiation to identify alterations to their properties. POLYM. ENG.
