项目摘要
This Faculty Early Career Development (CAREER) project is an integrated research and education study centered on carbon nanotube (CNT)-based multifunctional coatings. Multifunctional coatings are material systems intentionally encoded with multiple engineering functionalities. The main research objective is to derive and validate the fundamental electromechanical behavior of multifunctional layer-by-layer CNT-polyelectrolyte (PE) thin films. Their coupled electrical and mechanical properties will be tested using experiments, characterized by theory, and simulated numerically across different length scales. First, CNT-PE thin films will be subjected to mechanical, fracture, and viscoelastic tests. A micro-electro-mechanical model will then be derived and validated for simulating thin film electromechanical response to different types of applied loads. Next, the model will be used to evaluate the effects of defects on bulk film linear/non-linear properties, as well as the effects of inhomogeneity of large coatings. Finally, a finite element model that incorporates spatial variations of electromechanical properties will be created for assessing and comparing to experiments their spatial sensing and mechanical behavior. This research will explain, from a physics standpoint, why these nanocomposites possess such unique linear/non-linear and static/time-dependent electromechanical behavior. The research impacts will be the derivation of new theory, numerical models, and experimental data that describe, in a holistic sense and across different length scales, the electromechanical behavior of these CNT-based multifunctional thin films. The experimental methods, analysis techniques, and models developed are applicable to a broad array of nanocomposites and coatings. New knowledge and innovations in areas such as multi-physics modeling, mechanics, materials science, nano-engineering, sensor systems, and multifunctional coatings will be generated. The lessons learned will facilitate the implementation of future coatings in real-world applications. Integral to this CAREER project is also an education/outreach plan to equip future students/workforce with the knowledge, skills, and business training for them to pursue and secure careers in nanotechnology-enabled multifunctional materials. A nanoscience for sensing course series will be developed. Students from underrepresented and economically disadvantaged groups and female students will be recruited for this new effort and for research. Course and research results will be disseminated via a website, online videos, presentations, and publications.
这个教师早期职业发展(CAREER)项目是一个以碳纳米管(CNT)为基础的多功能涂料为中心的综合研究和教育研究。多功能涂层是一种具有多种工程功能的材料系统。主要研究目标是推导和验证多功能层接层碳纳米管(PE)薄膜的基本机电行为。它们的耦合电气和机械性能将通过实验进行测试,其特征在于理论,并在不同的长度尺度上进行数值模拟。首先,CNT-PE薄膜将进行机械,断裂和粘弹性测试。一个微机电模型,然后将推导和验证模拟薄膜机电响应不同类型的施加负载。接下来,该模型将用于评估缺陷对体膜线性/非线性特性的影响,以及大涂层的不均匀性的影响。最后,将创建一个有限元模型,该模型包含机电特性的空间变化,用于评估和比较实验的空间传感和机械行为。这项研究将从物理学的角度解释为什么这些纳米复合材料具有如此独特的线性/非线性和静态/时间依赖的机电行为。研究影响将是新理论,数值模型和实验数据的推导,这些理论,数值模型和实验数据从整体意义上和不同的长度尺度上描述了这些基于CNT的多功能薄膜的机电行为。实验方法,分析技术和模型开发适用于广泛的纳米复合材料和涂层。将产生多物理建模,力学,材料科学,纳米工程,传感器系统和多功能涂层等领域的新知识和创新。所吸取的经验教训将促进未来涂料在实际应用中的实施。这个职业生涯项目的组成部分也是一个教育/推广计划,为未来的学生/劳动力提供知识,技能和商业培训,让他们追求和确保纳米技术多功能材料的职业生涯。将开发传感纳米科学系列课程。这项新的工作和研究将招募来自代表性不足和经济弱势群体的学生和女学生。课程和研究成果将通过网站、在线视频、演示和出版物传播。
