Abstract
The crystal structure and morphology of Nylon 6,6 have been thoroughly investigated during the past sixty years. Three crystalline phases (alpha, beta and gamma) have been reported. Lath shaped single crystals have been obtained by solution crystallization methods using a number of organic solvents. Nylon 6,6 spherulites have also been extensively studied in bulk samples. The motivation of the present work in that the uniqueness of the H-bonding in the Nylon system has led to complicated crystal structures and morphologies. Given the extensive investigations that have been carried out in the past sixty years, solution grown Nylon single crystal and spherulitical morphologies have not been systematically studied. Most of the previous work focuses on relatively large super cooling crystallization and lath shape single crystals are unanimously observed. On the other hand, the structure complexity occurs at the relatively high temperature at which structural transition known as Brill transition occurs. It is thus our intention to complete the Nylon 66 morphological map for different crystallization conditions and investigate Nylon 6,6 single crystals/spherulites structure and morphology at both high and low super cooling temperatures.
