Thermal conductivity measurements indicated that the thermal coefficient scaled linearly with GNP loading, where a value of 2.0W/m*k was achieved at a loading of 40%. Tensile measurement indicated that the modulus increased, linearly with GNPs loading, while the IZOD impact and toughness after an initial decrease, remained constant for loading up to 50%. The torque required for extrusion increased only by 25% over this range indicating that the compound remained processable despite the high loading content. SAXS showed a large decrease in the amount of lamellar folding relative to the neat PP sample, while WAXS and DSC measurements, indicated a slight increase in the degree of crystallinity . These results are consistent with strong adsorption of the PP chains to the GNP, which, while maintaining crystallinity, disrupts the lamellar structure. Cone calorimetry showed that nanocomposites with 10% loading or higher exhibited a dramatic decrease in heat release and mass loss rates. The time to ignition initially decreased relative to the neat PP, then increased and surpassed it by a factor of 2 at 40%. These results paralleled those from conductivity/frequency measurements indicating that percolation occurred. Hence thermal phonon dissipation was effective for a slowly approaching heat front while contact was required for a rapidly approaching front."},{"label":"dcterms.available","value":"2017-09-20T16:50:06Z"},{"label":"dcterms.contributor","value":"Rafailovich, Miriam H"},{"label":"dcterms.creator","value":"Yang, Kai"},{"label":"dcterms.dateAccepted","value":"2017-09-20T16:50:06Z"},{"label":"dcterms.dateSubmitted","value":"2017-09-20T16:50:06Z"},{"label":"dcterms.description","value":"Department of Materials Science and Engineering."},{"label":"dcterms.extent","value":"136 pg."},{"label":"dcterms.format","value":"Monograph"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/76364"},{"label":"dcterms.issued","value":"2015-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2017-09-20T16:50:06Z (GMT).
