Abstract: GOALI Tribology of Nanocomposites This collaborative proposal between the University of Florida (W.G. Sawyer), Rensselaer Polytechnic Institute (L.S. Schadler) and Albany International (G. Toney) teams a tribologist and a materials scientist with a company focused on developing nanomaterials with improved wear behavior. 1.0 Intellectual Merit The overall scientific goal of the project is to gain fundamental understanding of the wear mechanisms in filled polymers by: a) experimentally isolating the effects of particle size (10 nm to 10 um), particle aspect ratio (1 to 1000), dispersion, filler / matrix interface, and matrix properties on performance, b) obtaining a parametric understanding of the correlation between wear behavior and other mechanical properties, and c) modeling of the wear properties. Polymer nanocomposites significantly improve the tribological performance when compared to traditional filled polymers. It is unclear for non-lubricious nanoparticles what the mechanism is that lowers the coefficient of friction. Finally, nanoparticle filled polymers have not been comprehensively explored for wear applications despite evidence suggesting large improvements in performance. 2.0 Broader Impacts The impact of these new materials in polymeric bearings will be broad, covering the spectrum from industrial applications needing dry sliding bearings, to orthopaedic implant materials, to self-lubricating bearings for space environments. An indication of the industrial interest in this field is the support of Albany International for this work (~$60K). They are supporting a full time graduate student at Rensselaer and have also supplied funds to Florida for wear testing. They will be hiring a graduate student into a co-op position in order to transfer technology developed by Florida and Rensselaer and provide industrial experience for the student. Students will travel between both Rensselaer Polytechnic Institute in Troy NY and the University of Florida in Gainesville FL to broaden their knowledge in the synthesizing and processing of nano-particles and composites and tribological testing and modeling, respectively.

摘要：纳米复合材料的目标摩擦学佛罗里达大学（W.G. Sawyer），Rensselaer理工学院（L.S. Schadler）和奥尔巴尼国际（G. Toney）之间的合作提议，一家培养基团队和一家材料科学家与一家公司的材料科学家专注于发展纳米材料具有改善的磨损行为。 1.0智力符合该项目的总体科学目标是通过以下方式获得对填充聚合物中磨损机制的基本了解：磨损特性。 与传统填充的聚合物相比，聚合物纳米复合材料可显着改善摩擦学性能。 对于非润滑纳米颗粒而言，尚不清楚该机制降低了摩擦系数。 最后，尽管有证据表明性能有很大改善，但尚未全面探索纳米颗粒填充的聚合物。 2.0更广泛的影响这些新材料在聚合物轴承中的影响将是广泛的，涵盖了需要干滑动轴承的工业应用，到骨科植入物材料到空间环境中的自润滑轴承。 该领域的工业兴趣表明，奥尔巴尼国际公司（Albany International）为这项工作提供了支持（约合6万美元）。 他们支持伦斯勒（Rensselaer）的全职研究生，还向佛罗里达州提供了资金进行磨损测试。 他们将雇用一名研究生担任合作社职位，以转移佛罗里达州和伦斯勒（Rensselaer）开发的技术，并为学生提供工业经验。 学生将在Troy NY的Rensselaer理工学院和Gainesville FL的佛罗里达大学之间旅行，以扩大他们在纳米粒子和复合材料的合成和加工方面的知识，并分别扩大他们的知识，以及分别为摩擦学测试和建模。
