WebFeb 16, 2024 · The doping concentration increases as the PPy crystallinity becomes poor in experiment, while the carrier density increases as well. Thus, it can conclude that the transport property change from metallic-like to semiconducting is related to the increase of charge carrier density (corresponding to the gradually decrease of FeCl 3 concentration). Webamorphous and disordered crystalline regions were melt-recrystallized during the heat treatment, which probably resulted in enhanced crystallinity.

"WebCrystalline structures are more organized than amorphous regions and they take up less space. So the more a material crystallizes, the more it shrinks as it cools. Uneven cooling caused by either varying wall thicknesses or poor temperature control in the mold results in different levels of shrinkage in different areas of the part. " - Poor crystallinity
