U.S.-China Cooperative Research: Polycarbonate/Epoxy Copolymers and Coating Systems

该奖项支持康涅狄格大学的詹姆斯·贝尔和中国科学院化学研究所于云超在聚碳酸酯/环氧共聚物和涂料系统方面的合作。聚碳酸酯广泛用于光学应用，如飞机和火车的窗户，或眼镜，但耐擦伤和耐磨性较差。环氧树脂相当坚硬，但没有聚碳酸酯的韧性和抗冲击性。在这项计划中，将研究环氧-聚碳酸酯反应体系的力学和化学性能，以及在固体聚碳酸酯上反应的环氧涂层的性能。这项研究可能导致具有韧性和表面硬度的改进复合材料，并将有助于阐明高玻璃化转变温度聚合物的增韧机理。

This award supports collaboration on polycarbonate/epoxy copolymers and coating systems between James Bell, University of Connecticut and Yu Yunchao, Chinese Academy of Sciences' Institute of Chemistry. Polycarbonate is widely used for optical applications such as windows in airplanes and trains, or for eyeglasses, but has poor scratch and abrasion resistance. Epoxies are considerably harder, but do not have the toughness and impact resistance of polycarbonate. In this proposal, the mechanical and chemical properties of epoxy-polycarbonate reacted systems will be investigated, as will the properties of reacted epoxy coatings on solid polycarbonate. This research could lead to an improved composite with both toughness and surface hardness and should help illuminate the mechanism of toughening of high glass transition temperature polymers.
