U.S.-Turkey Cooperative Research: Development of Environmentally Benign Processes for the Fabrication of Self-Cleaning and Self-Healing Surfaces

0422896 Wu描述：该项目支持由加州大学化学与环境工程系教授Jianzhong Wu领导的美国团队和由土耳其Kocaeli大学化学系教授Husnu Yildirim埃尔比勒领导的土耳其团队之间的合作项目。 研究目标是开发环境友好的工艺，用于大规模制造超疏水表面，这些表面有望实现众多的商业和军事应用。这些团队将研究在超临界二氧化碳中制备纳米级超疏水颗粒的详细方案，以及这些颗粒在各种表面的组装。 美国团队将进行分子建模和模拟，以研究粒子形成和自组装的微观细节，并为实验系统的设计和优化提供建议。与此同时，PI和他的土耳其团队的同事将合成氟化聚合物，用于在CO2中形成纳米颗粒，并进行实验以验证理论预测，根据理论设计制造表面，并表征和测试预期表面的性能。 该项目很可能会导致超疏水表面领域的重大进展，以及制造它们的有趣的新方法。合作是在两个具有互补资格和机构设施的团队之间进行的，因为美国PI在理论建模方面具有丰富的经验，而土耳其团队在超疏水表面的合成方面具有丰富的经验。 范围和更广泛的影响：在工业和化学应用中，致癌有机溶剂被广泛使用，这些溶剂进入地下水，需要更换。 超临界二氧化碳是一种良性溶剂，可能是一个正确的替代品，因为它找到了更广泛的用途。 美国研究生将通过在外国机构工作，并与外国研究生合作，获得国际经验，并将参与理论和实验研究。 该项目由OISE和化学和运输系统司共同资助。

0422896 WuDescription: This project supports a cooperative project between a US team, led by Professor Jianzhong Wu, Department of Chemical and Environmental Engineering University of California, Riverside, California and a Turkish team led by Professor Husnu Yildirim Erbil, Department of Chemistry, Kocaeli University, Turkey. The research objective is to develop environmentally friendly processes for the large-scale fabrications of superhydrophobic surfaces that promise numerous commercial and military applications. The teams will study the detailed schemes for the preparations of nanoscale superhydrophobic particles in supercritical carbon dioxide and the assembly of these particles at various surfaces. The U.S. team will perform molecular modeling and simulations to investigate the microscopic details of particles formation and self-assembly and give a recommendation for the design and optimization of experimental systems. Concurrently, the PI and his colleagues from the Turkish team will synthesize fluorinated polymers for the formation of nanoparticles in CO2 and perform experiments to validate the theoretical predictions, to fabricate the surfaces following the theoretical design, and to characterize and test the performance of expected surfaces. It is likely that this project will lead to significant advances in the area of superhydrophobic surfaces, and to interesting new methods for fabricating them. The collaboration is between two teams with complementary qualifications and institutional facilities, as the U.S. PI has strong experience in theoretical modeling, and the Turkish team has extensive experience on the synthesis of superhydrophobic surfaces. Scope and broader impacts: There is widespread use of carcinogenic organic solvents, which find their way into the water table, in industrial and chemical applications, and these need to be replaced. Supercritical carbon dioxide is a benign solvent that may be a right replacement, as it find its way into more wide spread use. U.S. graduate students will gain international experience by working in the foreign institution, and by working with foreign graduate students, and will be involved in both theoretical and experimental research. This project is funded jointly by OISE and the Division of Chemical and Transport Systems.
