Multicomponent Drying of Semicrystalline Polmer Films

本提案请求(支持规划访问，作为爱荷华州立大学(美国)首席研究员(PI)博士、伊兹密尔理工学院(土耳其)的Sacide Alsoy博士和以色列理工学院(以色列)的Joseph Miltz博士，致力于研究半结晶聚合物包装材料的多组分干燥机理)。这一合作的想法诞生于美国-以色列-土耳其三国会议期间，由国家科学基金会主办，于1999年3月在以色列海法举行。在包装材料的情况下，溶剂去除是一个关键的加工步骤，其中许多是由半结晶聚合物制成的。因此，了解这一过程的机理对工业干燥过程有着重要的影响。这三位研究人员的专业知识在聚合物科学中的这一工业和基本重要问题上完美互补。在食品包装应用的背景下，将使用双管齐下的方法来处理半结晶聚合物的多组分干燥问题。研究干燥条件对最终产品影响的实验方法将与数学模型相辅相成，以实现干燥条件和干燥机设计的优化。这三名调查人员有机会在以色列互动，并参观了可用的设施。然而，重要的细节仍有待解决，调查人员也将从检查其他项目工地中受益匪浅。因此，要求国家科学基金会提供支持，使私人投资能够访问土耳其现有的设施，并制定细节，使三名调查人员能够提交合作研究提案。

ABSTRACTCTS-9910162Mallapragada, S. K.Iowa State U.This proposal requests (support for a planning visit as part of a potential tri-national collaborative effort between the principal investigator (PI) Dr. (Surya) Mallapragada at Iowa State University (USA), Dr. Sacide Alsoy at Izmir Institute of Technology (Turkey) and Dr. Joseph Miltz at Technion - Israel Institute of Technology (Israel), devoted to investigating the multicomponent drying mechanism of semicrystalline polymer packaging materials. The idea for this collaborative was born during Tri-National US-Israel-Turkey sponsored by the National Science Foundation and held in Haifa, Israel (in March 1999). Solvent removal is a key-processing step in the case of packaging materials, many in which are made from semicrystalline polymers. Therefore, understanding the mechanism of this process has a significant impact on industrial drying processes. The expertise of the three investigators perfectly complement each other for this industrially and fundamental important problem in polymer science. A two pronged approach will be used to deal with the problem of multicomponent drying of semicrystalline polymers in the context of food packaging applications. Experimental approaches to investigate the effect of drying conditions on the final product will be complemented with mathematical modeling to enable optimization of drying conditions and dryer designs. The three investigators have had an opportunity to interact in Israel and tour the facilities available. However, important details still need to be resolved and the investigators would benefit greatly from inspecting the other project sites as well. Therefore, support is requested from NSF to enable the PI to visit the facilities available in Turkey and work out the details to enable a collaborative research proposal to be submitted by the three investigators.
