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 layers at multiscale (e.g., nano, micron, and macro scales) and their effects on the processing-structure relationship, especially the nanoparticle assembly with different mechanisms, will be the focus of this research. In particular, thermoplastic and thermoset polymers, as well as nanoparticles of various morphologies (e.g., 1D or 2D), have been used for scalable fabrication of 1D fibers, 2D coatings, and 3D architectures via 3D printing. The demonstrations in structural supports, thermal dissipations, electrical conductors, plastics recycling, stimuliresponsive systems, and tissue scaffolds show massive potential in national defense, space exploration, energy storage, and human health.
