Abstract
Chitosan acetate-ammonium nitrate (NH 4NO 3) films have been prepared by the solution-cast technique. Fourier transform infrared spectroscopy (FTIR) showed that complexation has occurred. FTIR exhibited shifts in amine and carbonyl bands from 1553 to 1520 cm −1 and 1636 to 1617 cm −1. A new peak was also observed at 1746 cm −1. XRD shows that all complexes are amorphous. The highest conductivity at room temperature is 2.53×10 −5 S cm −1 for the film containing 45 wt% NH 4NO 3. The conductivity of the samples is dependent on the number of mobile ions and mobility.
