The adhesion of polymers underpins numerous applications ranging from MEMS to tissue engineering. The complex relationships between surface chemistry, viscoeleastic properties, and spatial heterogeneities create unique challenges in developing fundamental principles to actively guide surface-driven phenomena, such as directed cell growth. This career program aims to develop novel, yet practical, patterns of surface chemistry, molecular architecture, and topography to not only control, but also understand, the fundamental principles of polymer adhesion.This research will impact future technologies while also advancing the fundamental knowledge of polymer adhesion. Specifically, the systematic control of patterns will be used to determine the physical relationship between the spatial frequency of heterogeneities and the activated mechanism of molecular dissipation in the near-surface material. The length scale of the surface patterns will provide insight into the primary length scales for the controlling mechanism of adhesion for soft-polymer architectures. The use of surface chemical and compositional patterns will probe the influence of neighboring polymer domains on the screening, or confinement, of the adhesion of local polymer molecules. The overall program will work toward the development of a unifying relationship between topography, surface chemistry, and polymer rheological properties in the context of polymer adhesion and tribology.%%%This Career Program is designed to have a broad impact on the education and future careers of high school students, undergraduates and graduate students, as well as on the success of future important technologies. The balance of practical purpose with fundamental science provides a stimulating environment for undergraduate and graduate research. This environment will be augmented with formal collaborations with industry and national laboratories, such as the National Institute of Standards and Technology. Specifically, the educational program will teach students the skills of project management, leadership, and mentoring through a dedicated program build around polymer science research. This program serves to strengthen industry and academia, while equalizing the opportunity for success for all populations, most importantly women and minorities. This equalization is targeted through the training of "soft" skills which often define career-advancement in both industry and academia. Furthermore, the incorporation of an outreach program as a training device for these "soft" skills will impact local underrepresented high school students by encouraging them to pursue science-related careers through an extended research experience. The technical research program will benefit society through the development of environmentally-friendly "smart" adhesives and anti-fouling coatings. Additionally, the power of combinatorial methodologies will be communicated to industry, academia, and most importantly future scientists through combinatorial-based research experiences for graduate and undergraduate students.

聚合物的粘附支撑着从MEMS到组织工程的许多应用。 表面化学、粘弹性和空间不均匀性之间的复杂关系在开发积极引导表面驱动现象（如定向细胞生长）的基本原理方面产生了独特的挑战。 该职业计划旨在开发新颖而实用的表面化学，分子结构和形貌模式，不仅可以控制，而且还可以理解聚合物粘附的基本原理。这项研究将影响未来的技术，同时也将推进聚合物粘附的基础知识。 具体而言，图案的系统控制将被用来确定非均匀性的空间频率和近表面材料中的分子耗散的激活机制之间的物理关系。 表面图案的长度尺度将提供对软聚合物结构的粘附控制机制的主要长度尺度的洞察。 使用表面化学和组成图案将探测相邻聚合物域对局部聚合物分子的粘附的筛选或限制的影响。 整个计划将致力于在聚合物粘附和摩擦学的背景下，发展形貌，表面化学和聚合物流变性能之间的统一关系。该职业计划旨在对高中生，本科生和研究生的教育和未来职业以及未来重要技术的成功产生广泛影响。 实用目的与基础科学的平衡为本科生和研究生的研究提供了一个激励的环境。 将通过与工业界和国家实验室（如国家标准与技术研究所）的正式合作来加强这一环境。 具体而言，教育计划将通过围绕聚合物科学研究的专门计划向学生传授项目管理，领导和指导技能。 该计划旨在加强工业和学术界，同时为所有人口，最重要的是妇女和少数民族提供平等的成功机会。 这种平等的目标是通过“软”技能的培训，这些技能往往决定了工业界和学术界的职业发展。 此外，将推广计划作为这些“软”技能的培训手段，将鼓励当地代表性不足的高中生通过延长研究经验从事与科学有关的职业，从而对他们产生影响。 该技术研究计划将通过开发环保的“智能”粘合剂和防污涂料造福社会。 此外，组合方法的力量将通过研究生和本科生基于组合的研究经验传达给工业界，学术界，最重要的是未来的科学家。
