报告摘要: Nano-carbons (nCs), including graphene, graphitic nano-platelets, and carbon nanotubes have been firmly established as materials having exceptional mechanical properties. For this reason, they continue to be attractive candidates for the reinforcement of polymer and bio materials. In more recent studies, it has been recognized that these nCs also greatly influence morphological development starting at the molecular level, where they can template orientation and crystallization of the polymer/bio-polymer during composite processing. These influences on the polymer morphology by the nC have been shown to control the overall mechanical behavior of the composite. The work outlined in this talk will highlight some of the interesting interfacial interactions between the various nCs and the polymer during processing of the composite, and the resultant formation of templated interphase morphologies. The eventual influence of these structures on the composite mechanical behavior is also discussed. Deeper fundamental understanding of the interaction between the polymer and nCs is a necessity for the design and fabrication of composite materials. Ultimately, controlling structural registry (i.e., uniformity spanning molecular to macro-scales) for these various nano-composites will lead to materials with mechanical properties which approach the theoretical property expectations.
