AbstractStructural changes in nylon‐6 film on doping with various concentrations of copper chloride (0.5, 1.25, 2.5, 5, and 12.5 w/w) have been investigated. Methods such as density measurement, analysis of infrared spectra, and wide‐angle X‐ray diffraction analysis have been employed to study these structural changes. It is found that doping up to 1.25 of copper chloride increases the crystallization of nylon‐6 in the α‐crystalline form. Further increase in the dopant concentration, however, gradually changes the crystal structure to hexagonal γ form with reduction in the total crys
