AbstractCTS-0129613Kilbey, S. MichaelClemson UniversityIn this exploratory project the PI and Co-PI will focus on creating a series of branched amphiphilic block copolymers and investigating how their assembly, organization and structure are different than brushes formed form linear polymers.In order to maximize the productivity during this one-year exploratory project, the synthesis efforts will focus three types of architectures. The PI and Co-PI will synthesize comb-block, star-block copolymers and make proof-of-concept syntheses of A2A'B and A3A'B copolymers. The A2A'B and A3A'B copolymers are novel materials. In terms of characterization, the PI and Co-PI will focus on two key techniques: They will use the surface forces apparatus (SFA) to investigate the structure of brushes made from the aforementioned materials; they will also investigate the surface morphology and organization using atomic force microscopy (AFM). The former technique will focus on the layers as they are assembled from a selective solvent, and the latter technique will examine dried layers after the assembly process. The focus here is to explore how the connectivity and size of the new, branched polymers affects the organization and structure of the brush layer.This is an Exploratory/GOALI grant in which the PI and Co-PI will collaborate with Dr. Victor P. Thalacker, Senior Laboratory Manager at 3M Corporate Process Technology Center in St. Paul, Minnesota.

摘要CTS-0129613 Kilbey，S.迈克尔克莱姆森大学在这个探索性项目中，PI和Co-PI将专注于创造一系列支化的两亲性嵌段共聚物，并研究它们的组装，组织和结构与线性聚合物形成的刷不同。为了在这个为期一年的探索性项目中最大限度地提高生产率，合成工作将集中在三种类型的架构上。 PI和Co-PI将合成梳形-嵌段、星形-嵌段共聚物，并进行A2 A 'B和A3 A' B共聚物的概念验证合成。 A2 A 'B和A3 A' B共聚物是新材料。在表征方面，PI和Co-PI将专注于两项关键技术：他们将使用表面力装置（SFA）研究由上述材料制成的刷子的结构;他们还将使用原子力显微镜（AFM）研究表面形态和组织。 前一种技术将集中在层，因为它们是从选择性溶剂组装，后一种技术将检查组装过程后的干燥层。重点是探索新的支化聚合物的连接性和尺寸如何影响刷层的组织和结构。这是一项探索性/GOALI资助，PI和Co-PI将与明尼苏达州圣保罗3 M公司工艺技术中心的高级实验室经理维克托P. Thalacker博士合作。
