Effect of nanoparticles and processing conditions on the development of structural hierarchy in injection molded nylon composites

Document Type


Publication Date



Preliminary studies on the basic structure developed in nylon 6 and its blends with nanoparticles are presented. The melting transition and crystallization behavior of compression molded nylon 6 and its nanocomposites are investigated using DSC and WAXD techniques. The structural hierarchy developed along and across the flow direction is also addressed using optical microscopy. Polarized optical microscopy revealed that the presence of nanoparticles causes significant enhancement of the preferential orientation through the thickness direction of the molded parts even at mold temperatures very close to the melting temperature.
