An attenuated total reflection FT-IR spectroscopic study of polyamide 6/clay nanocomposite fibers

摘要

An attenuated total reflection FT-IR spectroscopic study of the hydrogen bonding, molecular orientation, and crystalline phase transitions in polyamide 6 (PA6)/clay nanocomposite (PA6CN) fibers is proposed. The nanoscale dispersed clay layers lowered the degree of order of hydrogen bonding, affected little the hydrogen bonding strength, and increased the degree of orientation of both gamma crystalline and overall domains. A partial gamma to alpha phase transition appeared with time.
