X-ray diffractograms for a PVA film containing 5% w/w silver nitrate as a function of heating time at 140 °C. From bottom to top, the curves show the film diffractograms before heat curing, after the instrument temperature had reached 140 °C and at 15 min intervals thereafter. The increasing peaks at 38° and 44.5° 2-Theta arise from the creation of silver nanoparticles over time.
