US-Egypt Cooperative Research: Synthesis of Some Recycled Dendritic Curable Resins Based on PET for Coating Applications

项目描述：该项目支持德克萨斯州丹顿北德克萨斯大学材料科学与工程学院Witold Brostow博士与埃及开罗埃及石油研究所Ayman Atta博士的合作研究。他们计划研究合成一些基于PET的可再生树突固化树脂，用于涂料应用。聚合物基材料（PBMs）使用的迅速增加增加了石油作为聚合物合成起始材料的使用，也进一步增加了石油和/或天然气作为能源的使用，并产生了废物处理问题。这三个问题都可以通过回收来解决。PIs计划开发一种从饮料瓶、纺织品和其他来源回收聚对苯二甲酸乙二醇酯（PET）固体废物的方法。知识优势：几种类型的乙二醇将用于制造合适的羟基低聚物，用于创建基于聚酯，环氧树脂和二乙烯酯类型的可固化树脂和聚氨酯泡沫的新材料。糖酵解将在醋酸锰作为催化剂的存在下，在220摄氏度的常压下进行，以回收PET为基础的材料的机械和摩擦学性能将被确定。这样制备的材料将有各种各样的潜在应用，如可固化树脂和廉价材料（比基于原始PET的材料成本更低），可用于生产聚合物混凝土、泡沫和涂料。更广泛的影响：上面定义的三个问题的PET解决方案将极大地帮助解决环境和能源使用问题。在两个实验室的专业知识和资源的互补性的基础上，有显著的协同作用。埃及学生和来自北德克萨斯大学的美国学生将参与研究并参观彼此的实验室。结果预计将在《材料教育杂志》上发表。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

0710983BrostowDescription: This project supports collaborative research by Dr. Witold Brostow Materials Science and Engineering, University of North Texas, Denton, Texas, in collaboration with Ayman Atta, Egyptian Petroleum Research Institute in Cairo, Egypt. They plan to study the synthesis of some recycled dendritic curable resins based on PET for coating applications. Rapidly increasing use of polymer-based materials (PBMs) increases the usage of petroleum as the starting material for polymer synthesis, also increases further the use of petroleum and/or natural gas as energy sources, and creates a waste disposal problem. All three problems can be solved by recycling. The PIs plan to develop a method of recycling poly(ethylene terephthalate) (PET) solid waste from beverage bottles, textiles and other sources.Intellectual Merit: Several types of glycols will be used to make suitable hydroxyoligomers for creation of new materials based on curable resins of the polyester, epoxy and divinyl ester types and also polyurethane foams. The glycolysis will be carried out in the presence of manganese acetate as a catalyst under the atmospheric pressure at 220 degrees C. Mechanical and tribological properties of materials based on recycled PET will be determined. The materials so prepared will have a large variety of potential applications as curable resins and also inexpensive materials (lower cost than those based on virgin PET) to be used to produce polymer concrete, foams and coatings. Broader Impacts: A solution for PET of the three problems defined above would help greatly with environmental and energy use problems. There is significant synergy based on the complementarities of the expertise and resources in both laboratories. Egyptian students and US students from North Texas University will participate in the research and visit each others laboratories. Results are expected to be in refereed publications in the Journal of Materials Education. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
