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）的研究人员将与两位行业领导者Rohm哈斯和Johns Manville合作，在分子水平上对玻璃/聚合物相互作用进行基本了解。这将有助于开发危险性更低、化学性质更好的聚合物，从而有能力改变整个行业。 本研究将研究有机探针分子和聚合物组分与具有科学意义和技术重要性的多组分氧化物表面的相互作用。这些材料及其表面在能源、显示器和生物技术中非常重要。 具体来说，该研究将重点关注含有铝、硅和氧化硼的无碱玻璃，因为这些材料的表面很容易通过化学成分的变化进行改性，但也会受到环保水性聚合物的改性（例如，粘合剂和粘结剂）。良好控制的材料合成和加工将随后进行表征与技术的组合，将探索表面上的反应位点的结构以及表面位点与探针分子的相互作用的能量。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在两名PSU教职员工的实验室合作。 除了在科学文章中报告研究结果外，该项目中获得的所有数据都将上传到ChemXSeer，这是一个面向化学学术研究人员的门户网站。技术规格：从简单氧化物材料获得的物理和化学知识通常应用于多组分氧化物，尽管人们广泛认识到，在更复杂的系统的表面存在独特的反应位点和原子/分子尺度的异质性。 多组分表面的复杂性的增加，以及由此产生的影响聚合物结合到这些材料的表面，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进行研究。 与有机小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，拟议的研究旨在实现依赖于对聚合物/氧化物界面的理解的材料开发的范式转变。结果将提高性能，降低环境和健康影响，和/或减少新材料开发的时间和成本。参与这项研究的学生将获得对产品开发，绿色化学和制造业的基础研究的价值的赞赏。 氧化物表面和聚合物吸附物的IGC和NMR表征的结果将被扩展到工业实验室。与此同时，这项工作是足够的基础，影响其他领域和其他应用的氧化物/聚合物界面系统，通过其快速和有效的传播，在公开的文献，并通过网络使能的路线。

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.
