ABSTRACT
Advanced composite materials (ACMs), especially nanoparticle-reinforced polymer composites (NpRPCs), exhibit desirable physical and chemical properties that include low density coupled with directed high stiffness and strength, optimal dimensional stability, superior temperature, and chemical resistance, as well as relatively cost-efficient manufacturing. Successful manufacturing of high-performance nanocomposites depends on the precise control of processing factors, including (i) uniform dispersion of the nanoparticles, (ii) effective matrix-filler interfacial interactions at the molecular level, and (iii) alignment/orientation of the nanoparticle and/or polymer chains. Discussions of such processing-structure relationship especially the molecule-nanoparticle interfacial interactions and surface functions of nanocomposites will be the focus of this talk. In particular, both thermoplastic and thermoset polymers, as well as nanoparticles of various morphologies, have been used for scalable fabrication of one-dimensional fibers, two-dimensional coatings, and three-dimensional printed architectures. Also, detailed exploration regarding the manufactured microstructure using experimental and simulation methods (e.g., FEM and MD) is conducted to fundamentally understand the microstructure-property relationship in these polymeric composite systems.
Biography
