Molecular Layer Deposition of Hybrid Organic-Inorganic Polymer Films with Tunable Mechanical Properties

在这个由化学系的大分子、超分子和纳米化学项目资助的项目中，位于博尔德的科罗拉多大学的Steven乔治将开发新的表面化学，用于使用分子层沉积（MLD）技术沉积混合有机-无机膜。 其目标是制造具有可调机械，电气，化学，介电，光学和热性能的功能薄膜，以实现薄膜器件的构建。 目标属性包括：膜中聚合物链之间的高度交联，以获得高韧性和高临界应变以及可压缩性，从而获得柔性和体积膨胀公差。 更广泛的影响涉及学生培训和发展，与有兴趣在未来产品中使用混合有机-无机MLD薄膜的公司合作，以及通过科罗拉多大学向导计划向小学生传达科学的兴奋。 这项工作将开发新的方法，使技术上重要的薄膜与定制的机械性能。 这些薄膜可能会影响使用保护和阻隔层、柔性和导电薄膜以及顺应性和功能性涂层的技术。

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Steven George of the University of Colorado at Boulder will develop new surface chemistries for depositing hybrid organic-inorganic films using molecular layer deposition (MLD) techniques. The goal is to fabricate functional films with tunable mechanical, electrical, chemical, dielectric, optical and thermal properties to enable the construction of thin film devices. Targeted properties include: high cross-linking between polymer chains in the film for high toughness and high critical strain and compressibility for flexibility and volume expansion tolerance. The broader impacts involve student training and development, collaborations with companies interested in using hybrid organic-inorganic MLD films in future products, and communicating the excitement of science to elementary school students via the University of Colorado Wizard Program. This work will develop new way to make technologically important thin films with customizable mechanical properties. These films could impact technologies that use protective and barrier layers, flexible and conductive films, and compliant and functional coatings.
