Mechanoresponsive Polymer-Matrix Composites
Abstract
The proposed effort seeks to develop a detailed understanding of the interplay between nanoparticle dispersion, matrix-nanoparticle adhesion, and thermomechanical composite performance. A thorough understanding of the structure-performance relationships in polymer matrix composites has the potential to enable the design of high performance materials with multiple additives and thus multiple functionalities. The proposed work seeks to develop polymer-matrix composites (PMCs) that incorporate strength-enhancing nanoparticles and diagnostic nanoparticles with the aim that these materials can direct the design of innovative stimuli-responsive composites. Specific tasks include (1) synthesizing a library of novel high performance prepolymers and resins with varying molecular weight, functionality, and crosslinking density; (2) tailoring the surface functionality of fluorescent nanofillers to improve dispersion within the polymer matrix, and demonstrate fluorescence quenching in the as-prepared state; (3) characterizing the PMC microstructure, thermomechanical properties, thermal stability, and strength and correlate these properties to nanoparticle loading; and, (4) utilizing the fluorescent nanofillers to diagnose composite failure mechanisms.
