Part 1:This Partnership in Research and Education (PIRE) project addresses critical research challenges for the development of Active Coating Technologies (ACTs) through an international research and educational platform with an aim to transform the human habitat and our ability to respond to disasters. These ACTs will generate fundamental scientific understanding that enables the design of novel materials and properties for the robust collection and purification of water, elimination/reduction of disease transmission, and efficient generation and storage of energy, and hence, will address societal needs that have high relevance for the world and the U.S. To this aim, the University of Pennsylvania has formed an international partnership with fourteen collaborators from six institutions within the Grenoble Innovation for Advanced New Technologies (GIANT) in Grenoble, France. The collaboration with Giant provides the complementary expertise and resources critical for the research. The domestic partners, namely, Alabama State University, Villanova University and Bryn Mawr College further increase the research depth and diversity of participants, who will take part in every aspect of the project including research and education at GIANT. Through the planned research programs every summer, the US team consisting of a post doc, an early career faculty, and graduate and undergraduate students from these domestic institutions and UPenn, will gain invaluable international research experiences at Grenoble. Other important educational components include industrial internships at Salvoy, a world leader in the area, as well as workshops to develop broader career skills, training for the communication of technical information, and the opportunity to innovate on a prototype "Relief Tent" that will showcase ACT research. The research will address fundamental and up-to-now unsolved, materials-related scientific problems that will be applicable to engineering better human habitats and emergency response structures. The integrated research and educational components of the project will contribute to preparing a globally-engaged science and engineering workforce and a new cadre of US scientists poised to be international scientific leaders.Part 2:To enable coatings that transform the human habitat, each ACT utilizes the versatility afforded by polymers, nanoparticles and their mixtures to create coatings with tailored chemistry, surface texture and function. ACT 1 (water management) seeks to understand how the size, geometry, and surface energy of hierarchically structured coatings influence wetting and water transport. GIANT adds expertise in photoreactive nanomaterials that, when combined with Penn's structured coatings, open new opportunities to manage water. US scientists can investigate wetting of structured coatings using micro beam x-ray scattering tools at GIANT. ACT 2 (suppression of disease transmission) will relate the mechanics and texture of nanobilayer and layer-by-layer coatings to bacteria adhesion and proliferation. GIANT's expertise in synthesis and visualization of biomacromolecules is critical for understanding how bacteria interact with novel surfaces. ACT 3 (energy conversion and storage) will design multilayered coatings to efficiently collect and convert light using textured surfaces from ACT 1 in combination with unique nanoparticles. These photovoltaic cells will be coupled with solid polymer electrolytes designed with fast ion pathways for next generation lithium ion batteries. GIANT's expertise in interrogating energy materials in-situ and in-operando is particularly unique. Five unifying principles and methods integrate the ACTs, including commonality of materials and approaches, the unifying role of theory and simulation, a need for mechanical characterization and robustness, novel methods for structure/property studies at GIANT, and the translation of basic research into applications in collaboration with industry.

第1部分：这一研究和教育伙伴关系(PERE)项目通过一个国际研究和教育平台解决了主动涂层技术(ACTS)发展面临的重大研究挑战，目的是改变人类栖息地和我们应对灾害的能力。这些行动将产生基本的科学认识，使人们能够设计新的材料和特性，用于强大的水收集和净化、消除/减少疾病传播以及高效的能源生产和储存，因此，将满足与世界和美国高度相关的社会需求。为此，宾夕法尼亚大学与法国格勒诺布尔的格勒诺布尔先进新技术创新(GIGER)内六个机构的14名合作者建立了国际合作伙伴关系。与巨人公司的合作为这项研究提供了至关重要的补充专业知识和资源。国内合作伙伴，即阿拉巴马州立大学、维拉诺瓦大学和布林·莫尔学院，进一步增加了参与者的研究深度和多样性，他们将参与项目的方方面面，包括GIGNAL的研究和教育。通过每年夏天计划的研究项目，由博士后、职业早期教师以及这些国内机构和宾夕法尼亚大学的研究生和本科生组成的美国团队将在格勒诺布尔获得宝贵的国际研究经验。其他重要的教育内容包括该领域的世界领先者萨尔沃伊的工业实习，以及培养更广泛的职业技能的讲习班，技术信息交流的培训，以及展示ACT研究的“救济帐篷”原型的创新机会。这项研究将解决与材料有关的基础性和迄今尚未解决的科学问题，这些问题将适用于设计更好的人类栖息地和应急结构。该项目的综合研究和教育部分将有助于培养一支全球参与的科学和工程劳动力和一支准备成为国际科学领导者的新的美国科学家队伍。第二部分：为了使涂层能够改变人类栖息地，每个ACT利用聚合物、纳米颗粒及其混合物提供的多功能性来创造具有量身定制的化学、表面纹理和功能的涂层。第1幕(水管理)试图了解分层结构涂层的尺寸、几何形状和表面能如何影响润湿和水传输。巨人公司增加了光反应纳米材料方面的专业知识，当与宾夕法尼亚大学的结构化涂层相结合时，将打开管理水的新机会。美国科学家可以在巨人实验室使用微束x射线散射工具研究结构涂层的润湿。第2幕(抑制疾病传播)将纳米胆层和逐层涂层的机制和纹理与细菌黏附和增殖联系起来。巨人公司在生物大分子合成和可视化方面的专业知识对于了解细菌如何与新表面相互作用至关重要。第三幕(能量转换和存储)将设计多层涂层，利用ACT 1的纹理表面与独特的纳米颗粒相结合，有效地收集和转换光。这些光伏电池将与为下一代锂离子电池设计的具有快速离子通道的固体聚合物电解质相结合。巨人公司在现场和现场审问能源材料方面的专业知识尤其独特。五个统一的原则和方法整合了ACTS，包括材料和方法的共性，理论和模拟的统一作用，机械特性和稳健性的需要，巨人组织结构/性能研究的新方法，以及与行业合作将基础研究转化为应用。
