New Findings from Northeastern University in Molecular Engineering Provides New Insights

June 25, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Molecular Engineering. According to news reporting originating in Boston, Massachusetts, by VerticalNews journalists, research stated, "PVA/single-walled nanotube (SWNT) composite fibers are fabricated using a steady shear-flow gel-spinning method. The resultant fibers show excellent tensile strength, modulus, and toughness of 4.9 GPa, 128 GPa, and 202 Jg(-1), respectively."

The news reporters obtained a quote from the research from Northeastern University, "Templated interfacial crystallization of PVA in the vicinity of SWNT is controlled by tailoring the degree of undercooling of PVA during the composite solution preparation. WAXD shows that the templated crystallization behavior of the PVA at the SWNT interfacial region is new. PVA/SWNT fibers that exhibit interfacial structure show a predominant crystallization plane of (001) as compared to the (101) plane seen in PVA/SWNT fibers without a distinct interfacial structure."

According to the news reporters, the research concluded: "This demonstrates that the PVA interfacial region around SWNT has denser crystalline chain-packing."
