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

在这个由化学部门的大分子、超分子和纳米化学项目资助的项目中，科罗拉多大学博尔德分校的Steven George将利用分子层沉积（MLD）技术开发新的表面化学方法，用于沉积有机-无机混合薄膜。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。目标性能包括：薄膜中聚合物链之间的高交联，具有高韧性和高临界应变，可压缩性，具有柔韧性和体积膨胀容限。更广泛的影响包括学生的培训和发展，与有兴趣在未来产品中使用有机-无机混合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。这项工作将为制造具有可定制机械性能的具有重要技术意义的薄膜开辟新的途径。这些薄膜可能会影响使用保护和屏障层、柔性和导电薄膜以及兼容和功能涂层的技术。

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.
