Mijovic9724714This two-year award will support collaborative research between Jovan Mijovic of the Brooklyn Polytechnic University and Francesco Bellucci of the University of Naples in Italy. The principal scientific objective of the proposed research is a systematic investigation of polarization due to migrating charges in crosslinking polymers by simultaneous impedance/near-infrared spectroscopy. The US side brings to the collaboration expertise in chemorheology of reactive polymers and relaxations and molecular motions in glass-forming materials. This is complemented by the Italian side's research on the diffusion of ions in various media and use of electrochemical methods to study different polarization mechanisms. The knowledge that emerges from this study will be attractive to the adhesive and coating, automotive, and aerospace industries in both countries.

这个为期两年的奖项将支持布鲁克林理工大学的Jovan Mijovic和意大利那不勒斯大学的Francesco Bellucci之间的合作研究。提出的研究的主要科学目标是通过同步阻抗/近红外光谱系统地研究交联聚合物中迁移电荷引起的极化。美方在反应性聚合物的化学流变学以及玻璃形成材料的弛豫和分子运动方面带来了专业知识。意大利方面还对离子在各种介质中的扩散进行了研究，并利用电化学方法研究了不同的极化机制。从这项研究中产生的知识将对两国的粘合剂和涂料、汽车和航空航天工业具有吸引力。
