项目摘要

NSF-CMS: Dendrimer-Based Nanocomposites for Nanotribological ApplicationsPI: M.L. Weaver (Metallurgical & Materials Engineering)Co-PI: S.C. Street (Chemistry)AbstractThis research focuses on developing a fundamental science-based understanding of the influence of dendrimer interlayers on the nanomechanical, nanotribological, chemical, and morphological properties of the ultrathin metal overlayer films. The technological motivation for this research is grounded in the desire to develop novel coatings that will increase the capability and durability of critical and emerging engineering structures based on thin film technology such as MEMS and NEMS (micro- and nano-elecromechanical systems) devices, and new materials for microelectronic packaging. Furthermore, a basic understanding of the changes in properties induced by dendrimer underlayers on films deposited with carefully controlled grain sizes, grain morphologies, and coating thicknesses can open new horizons in the development and application of thinner, more durable coatings. Educational efforts include the training of graduate students from the departments of Chemistry and Metallurgical and Materials Engineering and the integration of undergraduate students from the freshman and sophomore classes at The University of Alabama and from neighboring HBCU's into multidisciplinary research activities. This will provide those students with practical laboratory experiences above and beyond that normally associated with their academic coursework.

NSF-CMS：基于树枝状聚合物的纳米复合材料，用于纳米素化应用程序：M.L。 Weaver（冶金与材料工程）Co-PI：S.C。Street（化学）摘要这项研究重点是发展基于科学的基本理解，对树枝状机械层中对纳米力学，纳米机械，纳米素，化学，化学和形态学特性的影响。这项研究的技术动机是基于开发新颖涂料的愿望，这些涂料将提高基于薄膜技术（例如MEMS和NEMS（MIC-和MICRO-和NANO-ELECROMENICAL SYSSECTE））设备的薄膜技术的关键和新兴工程结构的能力和耐用性，以及微电包装的新材料。此外，对树枝状聚合物卧式诱导的特性变化的基本理解是在带有精心控制的谷物尺寸，谷物形态和涂层厚度的膜上，可以在开发和应用更薄，更耐用的涂层的开发和应用方面开辟新的视野。教育工作包括培训来自化学和冶金和材料工程系的研究生，以及在阿拉巴马大学新生和大二课程以及邻近HBCU的大一和大二课程的本科生融合到多学科研究活动。这将为这些学生提供实际的实验室经验，超出通常与他们的学术课程相关的实验室经验。
