The nano-carbons used in this work are layered carbon nano-chips that exhibit platelet morphology and are able to slide with respect to each other. Both filled and unfilled poly(vinyl alcohol) (PVA) fibers were studied to demonstrate how the presence of this nano-carbon material influences the polymer chain crystal structure and orientation to form highly ordered self-reinforcing interphase structures in the composite. In addition, the effect of these interfacial features on the tensile, dynamic mechanical properties, and rubbery behavior of the composites was also studied. It was found that at significantly low filler loadings of 0.5 wt%, interphase structure and property enhancement is most prevalent in the fibers. Differential scanning calorimetry (DSC), differential mechanical analyzer (DMA), wide-angle x-ray diffraction (WAXD) and small-angle x-ray scattering (SAXS) will be used in the characterization process.
