GOALI: Understanding Oxide-Polymer Interfaces to Enable Green Coating Technology

非技术描述：宾夕法尼亚州立大学（PSU）的研究人员将与两家行业领导者Rohm & Haas和Johns Manville合作，在分子水平上发展对玻璃/聚合物相互作用的基本理解。这将有助于开发危害更小、化学性质更温和的聚合物，从而有能力改变整个行业。本研究将研究具有科学意义和技术重要性的多组分氧化物表面的有机探针分子和聚合物组分的相互作用。这些材料及其表面在许多能源、显示和生物技术中都很重要。具体来说，这项研究将集中在含铝、硅和硼氧化物的无碱玻璃上，因为这些材料的表面很容易通过化学成分的变化进行修饰，但要受到环保水性聚合物（例如粘合剂和粘合剂）的修饰。控制良好的材料合成和加工之后，将采用一系列技术进行表征，这些技术将探索表面反应位点的结构以及表面位点与探针分子相互作用的能量。PSU的教师和行业参与者将定期会面，包括教师对工业研究中心的长期访问。这项研究还将涉及两名研究生和两名本科生，他们将在两名PSU教师的实验室中合作。除了在科学文章中报告研究结果外，本项目获得的所有数据将上传到ChemXSeer，这是一个化学学术研究人员的门户网站。技术细节：从简单的氧化物材料中获得的物理和化学知识经常应用于多组分氧化物，尽管人们普遍认为在更复杂的系统表面存在独特的反应位点和原子/分子尺度的非均质性。多组分表面复杂性的增加，以及由此产生的聚合物与这些材料表面结合的影响，将通过分析与无碱铝硼硅酸盐凝胶和玻璃纤维的化学相互作用来研究。与小有机分子和聚合物前体的相互作用将使用反相气相色谱（IGC）和固态核磁共振（NMR）的组合进行探测。通过与两个工业团队密切合作，一个来自玻璃公司，另一个来自聚合物涂层制造商，拟议的研究旨在带来依赖于聚合物/氧化物界面的材料开发的范式转变。研究结果将增强性能，降低对环境和健康的影响，和/或减少新材料开发的时间和成本。参与本研究的学生将了解产品开发、绿色化学和制造等基础研究的价值。氧化物表面和聚合物吸附物的IGC和NMR表征结果将被扩展，以允许将这项工作转化为工业实验室。与此同时，通过其在公开文献和网络上的快速有效传播，这项工作对于影响氧化物/聚合物界面系统的其他领域和其他应用具有足够的基础意义。

NON-TECHNICAL DESCRIPTION: Researchers at the Pennsylvania State University (PSU) will join in collaboration with two industry leaders, Rohm & Haas and Johns Manville, to develop a fundamental understanding of glass/polymer interactions at the molecular level. This will enable development of less hazardous and more chemically benign polymers that have the capability of transforming an entire industry. This research will study the interactions of organic probe molecules and polymer components with scientifically significant and technologically important multicomponent oxide surfaces. These materials and their surfaces are important in several energy, display, and bio-technologies. Specifically, the research will focus on alkali-free glasses containing aluminum, silicon, and boron oxides, as these materials present surfaces that are easily modified through changes in chemical composition but are subject to modification by environmentally friendly water-borne polymers (e.g., adhesives and binders). Well-controlled synthesis and processing of materials will be followed by characterization with a combination of techniques that will explore the structure of reactive sites on the surfaces as well as the energies of interactions of the surface sites with probe molecules. The PSU faculty and industry participants will meet with each other on a regular basis, including extended visits by faculty to industrial research centers. The research will also involve two graduate students and two undergraduate students working in collaboration across the labs of the two PSU faculty members. In addition to reporting research results in scientific articles, all data acquired in this project will be uploaded to ChemXSeer, a portal for academic researchers in chemistry. TECHNICAL DETAILS: Physical and chemical knowledge obtained from simple oxide materials is often applied to multicomponent oxides even though it is widely recognized that unique reaction sites and atomic/molecular scale heterogeneity exist at the surface of the more complex systems. The increased complexity of multicomponent surfaces, and the resulting implications for polymer binding to the surfaces of these materials, will be studied through analysis of chemical interactions with alkali-free aluminoborosilicate gels and glass fibers. Interactions with small organic molecules and polymer precursors will be probed using a combination of inverse gas chromatography (IGC) and solid-state nuclear magnetic resonance (NMR). By collaborating closely with two industrial teams, one from a glass company and the other from a manufacturer of polymer coatings, the proposed studies are intended to bring about a paradigm shift in the development of materials that rely upon an understanding of polymer/oxide interfaces. The results will enable enhanced performance, lower the environmental and health impact, and/or reduce the time and cost of new materials development. Students involved in this research will gain an appreciation for the value of fundamental research in product development, green chemistry, and manufacturing. Results from the IGC and NMR characterization of oxide surfaces and polymer adsorbates will be extended to allow translation of this work to industrial labs. At the same time, the work is sufficiently fundamental to impact other fields and other applications of oxide/polymer interface systems through its rapid and effective dissemination in the open literature and via cyber-enabled routes.
