Integrated Multifunctionality in Pixelated Polymer Nanocomposites
Abstract
This proposal seeks to discover the science in preparing pixelated polymer nanocomposites by directed self-assembly of liquid crystalline polymer network (LCNs). Patterning the local orientation and alignment of nanoinclusions within these material systems will enable concurrent control of functional properties and is a distinctive approach to grade and integrate multiple functions in materials. The technical effort will be founded on our expertise in materials chemistry, materials processing, characterization, and interface science. Our overall ambition is to develop fundamental mastery of materials chemistry and processing science to spatially grade thermal, electrical, or mechanical properties in multimaterial nanocomposites. Four objectives will define and guide this research activity- 1. Develop a basic understanding of the interface coupling between 2-D nanoinclusions and LCN as a function of variables such as nanoinclusion composition, nanoinclusion aspect ratio, and the degree of crosslinking in the polymer matrix. 2. Employ chemical functionalization to tune the coupling of the polymer network and model nanoinclusions. 3. Scope the resolution limits and interaction of the composites with directed selfassembly. 4. Print composites with variation in orientation and composition to integrate and tailor multifunctionality.
